Learning Outcome 6.2: Describe a database, a database management system, and the relational database model.

Q1: How is a file processing system or spreadsheet different to a database system? What disadvantages does the database approach address.

The tables in relational databases organize data in rows and columns, simplifying data access and manipulation. It is easier for manager to understand the relational model than put all data in one table. Besides, a relational database allows tables to be linked. And the linkage reduces data redundancy and allows data to be organized more logically. In a word, relational database is easier to control, more flexible, and more intuitive than approaches.

A Database Management System or (DBMS) is an essential tool for any organization or company in today’s modern world. A DBMS is “a group of programs that manipulate the database and provide an interface between the database and its users and other application programs” (Stair & Reynolds, 2011, p. 189). So in choosing the right DBMS there are many factoring issues with choosing the right one for the company or organization.

Computer databases are electronic filing system and are usually accessible on a computer network. The benefit of this method is that file access is so easy and quick by using a search process. Faster data access time can increase the productivity of managers and other employees who use data on a regular basis. Another benefit of such a system is that since electronic data is easy to backup in multiple locations, reducing the potential of a permanent data loss. The disadvantages of the electronic file system is that it prone to security since the computers are linked together on a network and hackers can get unauthorised access to your data. Another disadvantage is that it is costly to set up.

Our week 2 lesson stated that there are several steps to the research process, Chamberlain College of Nursing (CCN, 2015). My intent was to follow the instructions to the best of my ability. For some reason, I had varied off course and now I am trying to bounce back.

3. What would you recommend as effective methods for this organisation to store the data, and why? (Give two different options)

This paper will compare and contrast five different database management systems on six criteria. The database management systems (DBMS) that will be discussed are SQL Server 2000, Access, MySQL, DB2, and Oracle. The criteria that will be compared are the systems’ functionality, the requirements that must be met to run the DBMS, the expansion capabilities – if it is able to expand to handle more data over time, the types of companies that typically use each one, the normal usage of the DBMS, and the costs associated with implementing the DBMS.
