What Database Systems are and how they can be improved

Databases are an indispensable asset to every business . They contain valuable company Information which is the life blood of every organization . Without the right information , stored in a manner that is easily accessible by users of an organization , work may easily be hindered leading to huge losses in revenue and valuable resources like time and energy . A database may be defined as a huge collection

of data in the form of rows and columns that ensures that relevant information is well-stored and easily accessible (Whitten , Bentley Dittman 2001

Databases are built based on different technological models . Most databases are however , built based on the relational model , giving rise to Relational Database Management Systems (RDBMS . Other database models include the hierarchical and the network models (Biblio Tech Review 2001 . The relational database model is more common and is based on the use of a group of interrelated columns and rows , in form of a table The database itself is constructed as a collection of tables which consist of rows and columns that store information . The rows are referred to as records and they contain the actual data that constitute the database .

The basic feature of databases is that a single database can only keep details of similar records . This ensures that the data are properly stored and sorted for future reference . There are diverse applications available for designing , implementing and maintaining Databases Examples include Microsoft Access , Oracle Database , Microsoft SQL Server , Informix , Sybase and so on (Biblio Tech Review , 2001

All these software are reliable and come in different versions and grades . The version adopted by a company is usually determined by the size of the organization , the magnitude of information that requires storage , the resources available and the skills available to manage the database infrastructure

As an illustration , my organization uses Oracle and Microsoft Access Databases to store all the information and statistics of the computers on the network for easy allocation , connectivity and statistical purposes . There are also databases created to maintain the mail servers store the details of workers , equipment , and other relevant items on board the sub-marine . This ensures that records are easily located and utilized by multiple users within the organization . This helps to promote accountability within the organization . Structured Query Language (SQL ) is the standard programming language used to access the database and select the required information based on a given criteria at any point in time . Examples of fields contained in the databases include date , category , quantity , and so on . Every single item on the submarine is recorded in the database as...
