History of Database Technology and Data Models Essay Example for Free

History of Database Technology and Data Models Essay Imagine that you own bank and along with that, you own your bank’s credibility to your 100,000 clients. Just writing down each client’s information in a piece of paper would not be very secure and practical nowadays. That’s how an electronic database system comes in the picture. In this fast growing world, a technology like a database system is very necessary for establishments that hold a huge amount of data. However, the development of the current database technology and database models underwent an intricate process before it comes to a full bloom. In 1964, the word â€Å"database† technically denoted collections of data shared by end-users of time sharing computer systems and was coined by workers in a military information system. In addition, around 1960s, private companies started to own computers because of their increasing storage capabilities. Two data models were introduced: network (CODASYL) and hierarchical (IMS) model. During that time, database management systems were unsystematic. There no actual theoretical model about data organization. There was more emphasis on the processing of the records rather than the overall structure of the database system. During the 1970s, many astonishing breakthroughs on databases were witnessed. It was about the 1970 that E. F. Codd proposed a relational model for databases. The presented a system that separates the logical organization (schema) of a database from the physical storages and since that, it has been a standard in the field of computing. The term Relational Database Management System (RDBMS) was coined during this period. Theories about databases had finally made its way to the mainstream research projects. Two main prototypes for RDBMS were created: Ingres that was developed at UCB and this system used QUEL as query language and System R that was developed at IBM San Jose and this system used SEQUEL as query language. Meanwhile, in 1976, P. Chen suggested the Entity-Relationship (ER) model for database design which was proved to be vital in conceptual data models. This proposal enabled the designers to focus more on the data usage rather than its logical table structure. Commercialization of database systems for businesses began during the 1980s as demands for computers boomed. In addition, Structured Query Language (SQL) became a standard for database systems during these periods. DB2 became IBM’s flagship and development of IBM PC paved the way for more database companies and products like Dbase III and IV, Database Manager, OS/2 and Watcom SQL. The network and hierarchical models for database also started to disappear in the background. When the 1990s came, only a few surviving companies began to offer complex products at higher prices. Developments on database systems were more focused on client tool applications such as PowerBuilder (Sybase), Oracle Developer and VB (Microsoft). Some personal productivity tools related to database management were also created such as Microsoft Access and Excel. Some prototypes of Object Database Management System (ODBMS) also arose in the 1990s. It was also during the 1990s that the World Wide Web appeared. Large investments were made by Internet-related companies on Web and database connectors. Examples of these connectors are Active Server Pages (ASP), Java Servlets, JDBC, ColdFusion, Dream Weaver and Oracle Developer 2000. A solid growth of database applications was still observed in the early 21st century. Three companies continually dominate the database market: Oracle, IBM and Microsoft. In the near future, it is generally seen that databases management will be more sophisticated since huge systems (systems with storage measured in terabytes) are currently existing today. Most of these systems are used by most projects with science databases (genome projects, space exploration data). However, the â€Å"next great thing† on is the usage of XML with Java and other emerging technologies as a way to store data.

Gene Manipulation Essay -- essays research papers fc

Throughout time, man has always questioned science. Man has been curious about life, space, our bodies, and our existence. Man has gone as far as to the moon, and cloning. Everyday there are new developments being researched. Along with these developments come the people’s opinion. Many people question the positive outcomes and negative outcomes of procedures such as gene manipulation, cloning, in vitro fertilization and fetal tissue implants. To this day, scientists are researching and developing ways to â€Å"design† their children by selecting their sex, height, intelligence, and color of eyes. People question the morality of gene manipulation. Is it right to â€Å"design† our children? What are the consequences? The practice of gene manipulation is seen as Frankenstein-ish, but it is solely to benefit all humans with longer and healthier lives.   Ã‚  Ã‚  Ã‚  Ã‚  Gene manipulation is able to screen disorders of the fetus, prevent diseases from occurring to the following generations and allows parents to design their children. Prenatal testing is a very common procedure that is done . Nine out of ten pregnant women submit to some type of prenatal screening. (Golden) Dominant disorders such as Down Syndrome, which is a form of retardation, can be detected from a fetus. Since 1996, gene therapy has been the cure for patients suffering from a genetic disease. This is done by slipping a healthy gene in the cells of one organ of the patient. (Begley) Parents of this fetus can then decide on the procedures that will be done on their baby to cure him/her. Not only will the parents of the baby prepare for the surgeries but they can prepare themselves emotionally. This is helpful because during labor the parents will not be in shock when told that their child has complications. Older pregnant women who usually have more complications during pregnancy benefit from genetic screening. Doctors usually recommend â€Å"more invasive procedures† in which actual fetal cells are collected from the womb’s amniotic fluid or placenta . (Golden) Receiving the results from the tests, she can determine whether it is safe for her to continue with the pregnancy, especially since some tests provide accuracy as high as ninety-nine percent. (Golden) Unfortunately, not all test results come out positive. Approximately ninety-five percent of couples who receive â€Å"bad† news from genetic scr... ...nsequences, especially because of genetic screening. Many people may not be prepared to know nor prepared to want to know about the negative results of the tests. Should we then be ignorant about the situation and pretend not to know? Ignorance is not bliss. The more we know about curing people, the closer we get to improving our society. It may not happen now, but it will real soon.

Managerial Accounting Case Essay

In the Seligram case, the existing cost accounting system measured two components of cost: direct labor and burden. All burden cost, which is the overhead, was grouped into a single cost pool and was calculated only by using a burden rate per direct labor dollar. This may cause problems since direct labor and overhead are not consumed by the products in the same proportion. Simply using the same burden rate is obsolescent. First of all, direct labor hours per lot tested had been steadily declining, especially with the increase of dependence on vendor certification. This will result in the change of the burden rate. Besides, this system distorts the price to some extent, making the price for complex parts cheaper while price for elementary testing higher compared with price for outside services. What is more, the consequences brought from the introduction of high -technology components would decrease the direct labor hour. All of this was trending to higher burden rates and overall hi gher rates. Cost allocation based on current burden rate of 145% is calculated within the Exhibit1. Having noticed of the problems of the existing system, the accounting manager proposed a two-burden-pool method to allocate the burden cost. Under the two-burden-pool method, burden cost has been divided into two pools: one is the burden cost related to the administrative and technical functions and the other is test related burden. The former is calculated based on direct labor dollar, the latter one is calculated by using machine hours. This method takes other factors that cause the burden into account, which makes the cost allocation more accurate than the existing method. The result of two-burden-pool is as the follows. The consultant proposed a more detailed cost allocation method, i.e. separate burden centers from each of each test room and common technical and administrative pool so that a three-burden-pool is formed. Under this method, burden cost in test rooms would be allocated on a machine-hour basis, and technical and administrative costs would continue to be charged on a rate per direct labor dollar. This method is more accurate in allocating the burden cost by providing a cost of each product or job. Through this way, ETO could differentiate client and product and calculate the cost more accurately from direct data such as the machine hour to product a certain product, so that they need not to guess the real cost of that product by allocating cost according to estimation. Besides, due the process of automatic, direct labor dollar amount alone could not reflect the real picture of burden cost as before. So it is necessary to take other related factor into account when allocating burden cost and more detailed analysis of the allocation basis is needed. The allocation result of three-burden-pool is listed below: Since the three-burden-pool system is most accurate in allocating burden cost among those three methods, it is preferable. However, it does not mean the three-burden-pool system is perfect. Because this system provides more accurate and detailed information of the production process, it will cost more than the other two methods. In addition, the redesign of the three-burden-pool system could be expensive too due to the complexity of the system. In order to improve this system, ETO needs to pay attention of the relationship of cost and benefit. Besides, ETO could set up a system that is easy and effective to perform to save the cost of implicating three-burden-pool. Besides the consideration of proposed cost allocation methods, Seligram should also arrange the new equipment into an appropriate cost pool which indicates a more reliable estimation. Assuming that new equipment has a separate cost center, all variable cost, fixed cost and depreciation will be reported separately. The burden rate is only based on the machine hours of new equipment which are 400hr (Year1) and 2400hr (Year2-8). Additionally, we use Double-decline method for depreciation. Balance is shown in Exhibit4. The separate burden rate for Year 1 would be much higher than those in the following years due to set up costs (Exhibit 5). Burden rates combined with main testing room are calculated in Exhibit 6. All combined burden rates are much lower than the separate costing rates. We recommend choosing a separate cost center for new equipment, even though the rates are much higher. Due to the current situation that lower costs for more complex components, which is abnormal, separate method would reflect more accurate and reliable costs of new imported machines. Obviously, combined method would influence the presentation of true costs. The costs are reduced by other factors in main testing room. Higher burden rates are more reasonable that these new machines have higher cost in essence and also they are just for testing components from several specific clients. Higher burden rates are more accurate.

Essay On False Memory - 1409 Words

False Memories are fundamentally, unintended human errors, which results in people having memories of events and situations that did not actually occur. It’s worth noting that in humans there are both true and false memories, these false memories occur when a mental experience is incorrectly taken to be a representation of a past event. For example, when people are asked to describe something that happened at a particular time, people rarely deliver accurate answers. Based on research, in eyewitness testimony, the confidence people show while recalling a memory is not an accurate representation of the truth.

In the first trial, the participants were asked to press the â€Å"start trial† button because a fixation dot would appear in the middle of the screen. The participants were asked to stare at the computer until a sequence of words appeared, with each word was presented for one second. After a full sequence was presented, a set of buttons were shown, each labeled with a word. Some the words were on the list, and some were not. The participant’s task was to click or tap on the buttons to indicate which words were in the sequence. The sequence of words consisted of the actual words shown or related or unrelated words. For example, some trials consisted of all sleep related content to see if the participant would select items that were related or select items that were not in the sequence. After identifying the words that were shown in the sequence, they would receive feedback on the accuracy of their memory.

The Scarlet Letter, By Nathaniel Hawthorne - 1700 Words

Children have sponge-like mindsets that are full of curiosity and through each negative and positive encounter, they are able to learn from their experiences. Through their experiences, they are able to be more perceptive about their surroundings and are more honest than adults because they do not know what they say is either right or wrong. Children differ from adults in their potential for expressing these perceptions because they are not afraid to say or express anything but the truth. The children in Nathaniel Hawthorne’s novel, The Scarlet Letter, are presented as more perceptive and honest than adults due to their actions of perceiving Hester’s scarlet letter, expressing their opinions without knowing if it is right or wrong, and their willingness to ask questions. In the Scarlet Letter, Hester’s daughter, Pearl, has a willingness to ask questions about the scarlet letter on Hesters chest to help her have a better understanding of why her mother wears it. P earl shows how different a childs mind is from an adults since she does not understand the mark on her mother s chest is a punishment. Children are able to be more perceptive and honest than adults because they express their ideas out loud without knowing if it is either correct or incorrect; despite how rude it might be.

Beatles Memorabilia Intellectual Property/Contract

Question: Discuss about theBeatles Memorabilia Intellectual Property/Contract. Answer: Intellectual Property Intellectual property refers to innovation that is brought about by intelligence and creativity of the inventor. They include things such as designs or manuscript that an individual can have right over and can apply for a trademark, copyright, patent, industrial design rights and trade secrets in certain jurisdictions(Rimmer, 2008). The intellectual property concept was actually established by the British statute of Ann (1710) and the statute of monopolies (1624) appears to be origins of patent law and copyright correspondingly. There is an automatic protection of copyright if an authorship original work is fixed in a concrete medium of communication. Fixed means a work is "adequately enduring or steady to allow it to be perceived, duplicated, or else communicated for a time that is more than transitory period. In the case of Bleistein v. Donaldson Lithograph 1903, Justice Holmes stated, the policy judgment that encourages the production of wheat also requires the protection of a lot of chaff while warning against the use of aesthetic criteria(Mark Davison, 2015). Nevertheless, it should be noted that copyright protects duplication of expression of the work itself and not the idea behind it. Since Paul is the owner and manager of Fab Four, he is the original owner of the copyright. Use of the Fab Four video to promote trivia night was an infringement of the copyright since there was no permission from Paul who was the original owner of the video in question. Under federal law, this infringement is considered a crime as copyright itself is a federal law(Jill McKeough, 2004). Paul could have a valid claim if can show that there was access to his work and the video is significantly similar to his. In court, an ordinary observer test is used to decide whether the work in question is similar. In this case, it is clear that Don has infringed the copyright. Don used Pauls work without permission, altered and used it in social media to market his fame and popularity. Don is in violation of production rights because of (the distribution right) distributing the altered video in social network and (the right to create derivative work), the mixed video is derivative of the original Fab Four video. There are six exclusive rights to the copyright owner over the copyrighted work. They are namely: Reproduction right- this gives the owner right to duplicate, copy, transcribe or imitate work in fixed form. Modification right- also derivative works right, is the right to twist the work and come up with a new work. This new work is known as derivative work. Public performance right- this is the right to act, show or transmit to public. Sound recordings do not enjoy this right. Distribution right- it is public distribution of copies through sale or lending Right to distribute copies or phonorecords- copyrighted to the public by any transfer methods. Public display right- transmitting or display to the public in the form of video or televising. In reference to the above copyright owner rights it clear that Don has infringed several of the rights. The derivative works right was infringed by mixing the original video with cats video. He showed the video to the public through social media as his own, which was an infringement of public performance rights. Contract A disclaimer or exoneration of liability is a contractual phrase intended to avoid an individual who engaged the contract from taking legal action and litigating for personal damages. When items are left in cloakroom service free, the one receiving goods must not be negligent and there are no contractual rights according to Griffin's words. She stated that if someone leaves a jacket or a coat on the rack of a crowded restaurant, realistically he/she does so at his/her own risk(Ewan McKendrick, 2015). If the place or restaurant was hired by an organization that the victim works with, then that person can claim for loss or damage to that organization since they are the ones who paid for that place and are therefore in an existing contract with the services offered in that venue. A consumer law specialist Margaret Griffins stated that, When you pay for a service, like a cloakroom service, under consumer law, you enter into a contract with the provider, which means theyre required to take reasonable care of your goods and perform the service with reasonable care and skill. In this case, a person who leaves his belongings can expect them to be properly and safely looked after and cannot be given to someone else with the wrong ticket(John W. Carter, 2007). Though in reality, it is always difficult to determine and prove how the lost item was like, according to Griffins one might have a case for compensation if given the wrong coat or the coat is lost. In some places, disclaimers are put to waive responsibility for lost items. While these disclaimers might once have some legal basis, Silverman Sherliker a senior partner with a law firm stated that, it can be deemed an unfair term to say you accept no liability, under Unfair Contract Terms 1980 legislation. Bob handed over his coat to Ringo, who works in the cloakroom and was issued with a ticket that has a disclaimer in the back. The disclaimer states, We do not take any responsibility or liability for clothing checked in to our cloakroom. The owners of Beatles Memorabilia are not liable for the loss of Bobs coat that he claims to be paid. In the first place, this a free service offered to the customer of and Bob did not pay for it. There is therefore no contract between Beatles Memorabilia and Bob. He will not receive any compensation for his coat. Contract Interchanging goods and services between human have been a continued basic activity between human beings. The essentiality of trade and shopping rely on fundamental dealings and people settled on the basic values in their transactions, which were mostly relied on promises among people. On the other hand, in the modern age, levels of trade have grown, for that reason firms and merchants required obligatory and binding authorities to ensure their dealings. Even in a tiny business people act in accordance with those kinds of authorities and their set procedures. Offers and invitation to treat are the most important examples of dealings, and they have specific procedures to secure transactions among people. A person who makes an offer to another person with an intention to enter into a contract is referred to as offeror. A binding contract comes into existence when the offeree accepts the offer(Eugene Clark, 201). On the other hand, an invitation to treat has a different definition. It m eans inviting a person to make an offer. When a seller displays the price of an item either as a price tag or on a price list board for customers to see it is termed as an invitation to treat. For there to exist a contract, the offer must be accepted and both parties should agree to the terms and conditions of the contract. Silence can never be considered as acceptance of the offer. The T-shirts cannot be sold to Barbara at $13.00 each. A price tag cannot be a contract if the price displayed by the seller is mistake. This is only considered as inviting a customer to make an offer and the seller does not necessarily need to accept the offer. A contract can only be formed when the seller accepts payment made by a buyer(Contrac, 2011). After this payment is made and accepted the seller is no longer obliged to make the buyer to pay any balance between the advertised price and the real price. For an online transaction, it might be more complicated. Andrew Barrows described an invitation to treat as "...an expression of willingness to negotiate. A person making an invitation to treat does not intend to be bound as soon as it is accepted by the person to whom the statement is addressed." Real offers can be accepted in formation of a contract while an invitation to treat is a representation that might not be accepted. A contract is deemed to be legally binding if a voluntary agreement is formed when an offerer makes an offer and the offeree accepts it. However, even if invitation to treat cant be accepted it should not be ignored since it can have some effects on the offer(S. A. Christensen, 2009). In case a person makes an offer while responding to an invitation to treat the offer may assume the provisions of an invitation to treat unless the person making an offer generates different terms. The t-shirts sold in the store are only unique to the store and there the store can set its price, as it considers profitable since no competitor has the kind of product. Ringo was directed to sell the t-shirts at price of $30.00, which were originally $45.00 each. Barbara believed that the price of the t-shirts was $13.00 as indicated white board. However, this price came as a result of misunderstanding between the manager and Ringo. Therefore when Barbara goes ahead to pay for five t-shirts $13.00 each it is obvious that her offer will be turned down. Either the seller can offer to sell the t-shirts at the original price of $45.00 or the discounted price of $30 since Barbara was not aware of any price before other than then one on the white board. Contract There are three basic features required for existence of a legally enforceable contract. There must be a contractual issue and acceptance of an offer. This implies that both parties entering into a contract agree to its terms and conditions, Both parties must show an intent to form a legally binding contract and Contract must be in support of consideration (an exchange of value). Already Joe owes the store a bill worth $180.00. When he offers the box of figurines to pay for his bill, it was accepted even without knowing what is inside. Regardless of what could be in the box after checking it Joe was not to be asked for any further payment. Yes. There existed a valid contract with Joe. A valid contract exists when an offer is made and accepted(Gillies, 2004). Since the offer that Joe made was accepted and his box of figurines accepted a deal was sealed hence a valid contract. All the basic features of a legal binding contract were honored in sealing this deal. Once an offer has been rejected, it ceases to exist. Rita made a counter offer by rejecting the earlier price quoted by the offerror and proposed a new price of $4500.00. It therefore means that there is no contract formed between the two. Counter offer refers to contract made to respond to another offer. Making counter offer means that there is an automatic rejection of the asking offer, which under terms of counter offer requires acceptance, or otherwise there is no contract existing. This implies that the original offer has been rejected and the game is tossed back to the offerror leaving him with only three choices. (1) To expressly accept the offer by replying or through implication (i.e. by not replying), (2) give another counter offer in response to the one the offeree made, or (3) expressly reject the offer. Note that no binding contract is creatable unless one party accepts the offer by another party. If there is a change of mind by offeree and tries to agree with the terms of the original offer a new offer will be formed in contractual terms. If Rita replied, by stating that she agreed to the asking price there was no contract and this cant restore the original offer. This became a new offer, which is not been accepted to. Usually when both sides makes offer and counter offer it brings confusion among them because they may not understand when the acceptance or rejection is made. An offer or counter offer can be revoked any time by one party before acceptance is made, according to the general rule(Australia, 2014). There can be no legal binding until an offer or counter offer is accepted and this is where complication lies in most cases. The law says there has been meeting of the minds when acceptance occurs and is communicated to the offeror. In Ritas case, she was offered the figurines at a price $5000. She rejected this offer by making a counter offer to buy the items at a price of $4500. Up to this stage, there is no legal binding contract as the buyer and the seller have different minds on the price of figurines. In the following morning, it is communicated to Rita that she can have the figurines at $4500 although she does not read the message up to 9.45am. The point is that acceptance of the counter offer that Rita made in response to the asking price has been communicated. After this communication, there is a legal binding since there exist consensus of minds(Contrac, 2011). A contract becomes binding when acceptance has been communicated to the offeror. About the same time (9.00 am) that acceptance message was sent to Rita, she also sent a message to revoke her counter offer and accept the prior offer of $5000 which the seller had revoked by accepting to the counter offer. This message is received at 9.30 am and seen at 10.00am. According to the electronic records the $4500 deal was fully communicated and was earlier acceptable to both parties. Ritas acceptance of $5000 was made at the same time with acceptance of $4500 but was seen later. At the same time, she had asked for cancellation of her counter offer, which could not be made before acceptance since the communication was late. My opinion is, Rita has made a new offer of $5000 that has been communicated to the seller but has not been accepted yet. There is no legal binding contract on the transaction. So the figurines have not been sold to Rita because there is no agreed price among the two. The $4500 that could have been binding was canceled by the new Ritas offer of agreeing to the original price, which the seller himself had changed mind on. References Australia, L. S. o. W., 2014.
