...CHAPTER 4 RELATIONAL DATABASES SUGGESTED ANSWERS TO DISCUSSION QUESTIONS 4.1 Contrast the logical and the physical view of data and discuss why separate views are necessary in database applications. Describe which perspective is most useful for each of the following employees: a programmer, a manager, and an internal auditor. How will understanding logical data structures assist you when designing and using database systems?</para></question><question id="ch04ques02" label="4.2"> Databases are possible because of their database management system (DBMS). As shown in Figure 4.2, the DBMS is a software program that sits between the actual data stored in the system and the application programs that use the data. As shown in Figure 4.4, this allows users to separate the way they view the data (called the logical view) from the way the data is actually stored (the physical view). The DBMS interprets the users' requests and retrieves, manipulates, or stores the data as needed. The two distinct views separate the applications from the physical information, providing increased flexibility in applications, improved data security, and ease of use. In a database system, the manager will rarely need to understand or be familiar with the physical view of the data. Nor, in most instances, will the internal auditor and the programmer as most everything they do involves the......

...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......

...Assignment: Databases Maurice Eugene Northam III DBM/380 January 12, 2015 Bill Enloe Databases Database Management Systems (DBMS) are mind boggling, mission-discriminating programming systems. Today's DBMS’s epitomize many years of scholastic of a, what's more, mechanical examination and exceptional corporate programming advancement. Database Management Systems were among the soonest broadly conveyed online server systems and, accordingly, have spearheaded configuration arrangements crossing not just information administration, additional system applications, working systems, and organized administrations. The early DBMS’s are among the most powerful programming systems in software engineering, and the thoughts and execution issues spearheaded for DBMS’s are broadly duplicated and reexamined. For various reasons, the least of database systems building design are not as extensively known as they ought to be. First and foremost, the connected database systems group is genuinely little. Since business compels just help a couple of contenders at the top of the line, just a modest bunch of fruitful DBMS’s usage exist. The group of individuals included in outlining and actualizing database systems is tight: numerous went to the same schools, took a shot at the same compelling exploration ventures, and worked together on the same business items. Second, scholastic treatment of database systems frequently disregards building issues. Course reading presentations of database......

...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......
