Preface
In recent years there have been significant advances in the development of high performance personal computer and networks. There is now an identifiable trend in industry toward downsizing that is replacing expensive mainframe computers with more cost-effective networks of personal computer that achieve the same or even better results. This trend has given rise to the architecture of the Client/Server Computing. The term Client/Server was first used in the 1980s in reference to personal computers on a network. The actual Client/Server model started gaining acceptance in the late 1980s. The term Client/Server is used to describe a computing model for the development of computerized systems. This model is based on the distribution of functions between two types of independent and autonomous entities: Server and Client. A Client is any process that request specific services from server processes. A Server is process that provides requested services for Clients. Or in other words, we can say “A client is defined as a requester of services and a server is defined as the provider of services.” A single machine can be both a client and a server depending on the software configuration.

...form. Once the system is done with the coding stage it tests the systems and sees to it that it is working as per the expectations or not. System implantation is one of the most vital phases as in this phase the analyst actually gives the system to the customer and expects for a positive feedback. Finally, the system maintenance is that the analyst needs to maintain the system and see to it that it working within the standards set. He needs to maintain the system by removing the defects of flaws occurred. I think this relates to database development because in 1960 the developers, Elliott and Strachan and Radford developed large scale functional business systems in an age of large scale business conglomerates. Information systems activities revolved around heavy data processing and number crunching routines. The database is also a design lie cycle in my opinion because it is design in different stages in storing data and each of the components in the database might work similar but also in different ways. In requirements analysis, the head topics that I found are: project management tools, five common errors, and business analysts....

...transformation processes. In actual sense, relational database offers a solution to this menace. Data organization, keeping, storage, and retrieval among other essentials can easily be realized by adopting relational data management model. In this kind of model, tables are made use of in such a way that data items are formally described and organized according to their level of relations. The data item contained in a given table represents a relation. I am convinced beyond reasonable doubt that through the use of relational database model, an organization can be able to effectively manage their wide range of information encountered on a daily basis. Relational database model offers a more efficient means of managing data. Some of the huge benefits are discussed as follows. A relational database is a collection of relations or tables. The rows of a table in a relational database are known as tuples and each column of a table is called an attribute. By definition, a relation becomes a set of tuples having the same attributes. Operations, which can be performed on the relations are select, project and join. The join operation combines relations, the select queries are used for data retrieval and the project operation identifies attributes. The information oif the organization can be captured, manipulated, managed, and shared, and the value the database brings to the organization is immense. The advantages of a relational database are that they contribute to sound logical......

Write a paper of no more than 1,500 words in which you respond to the questions designated for both scenarios. Scenario 1: You are a marketing assistant for a consumer electronics company and are in charge of setting up your company’s booth at trade shows. Weeks before a show, you meet with the marketing managers and determine what displays and equipment they want to display. Then, you identify each of the components that need to be shipped and schedule a shipper to deliver them to the trade show site. You then supervise trade show personnel as they set up the booths and equipment. After the show, you supervise packing the booth and all the equipment as well as schedule its shipment back to your home office. When the equipment arrives, you check it into your warehouse to ensure that all pieces of the booth and all the equipment are returned. If there are any problems due to shipping damage or loss, you handle those problems. Your job is important; at a typical show you are responsible for more than a quarter-million dollars of equipment. • In Scenario 1: o You need to track data about booth components, equipment, shippers, and shipment.

...IST 792 paper 2 Database security is a growing concern evidenced by an increase in the number of reported incidencets of loss of unauthorized exposure to sensitive data. As the amount of data collected, retained, and shared electronically expands, so does the need to understand database security. (Murray, 2010) Database security concerns the use of a broad range of information security controls to protect databases (potentially including the data, the database applications or stored functions, the database systems, the database servers and the associated network links) against compromises of their confidentiality, integrity and availability. It involves various types or categories of controls, such as technical, procedural/administrative and physical. Database security is a specialist topic within the broader realms of computer security,information security and risk management. Security risks to database systems include, for example: * Unauthorized or unintended activity or misuse by authorized database users, database administrators, or network/systems managers, or by unauthorized users or hackers (e.g. inappropriate access to sensitive data, metadata or functions within databases, or inappropriate changes to the database programs, structures or security configurations); * Malware infections causing incidents such as unauthorized access, leakage or disclosure of personal or proprietary data, deletion of or damage to the data or programs, interruption or denial......
