Today I’m going to talk about File Processing Systems V’s Databases. These are just different types of ways of storing data through the use of an information system.
In the beginning, there were file-processing systems. The first business information systems stored information by grouping similar data into separate files. The problems with this were:
- Duplication of data
- Data separated and isolated
- Application program dependant
- incompatible data files
- Difficult to understand
- Difficult to change file structure without modifying all programs that use data in that file
- More error prone when changes made in several different files
This then lead to the Database Approach which is:
A database is a self describing collection of logically related data, organised to meet the information needs of multiple users.
The key advantages of Databases are:
1. Data is integrated and stored centrally
- Management and control
- Easier to understand
- Data duplication is reduced
2. Analysis Capability
- Analyse/Query large volumes of data
- Speed of organising and retrieving data
3. Data is program independent (flexibility to add new applications easily)
Next blog I will discuss with you Database Management Systems. Hope ye have found it helpful thanks for reading!
