Storing Organizational Information - Database
As I said in previous entry, information are everywhere in an organization. So, it means that there must be one storage that used to store that info. The answer is......
DATABASE
There are 3 types model of database which is
- hierarchical database model
- network database model
- relational database model
The function for this 3 model is same - to store the info but the difference is the way the info is stored and each one of the model are suitable for particular types of information.
There are 2 elements of information that stored in the database which is, entity and attributes. Primary keys and foreign keys identify the various entity classes (tables) in the database
5 database advantages from business perspective....
flexibility
scalability & performance
information integrity
information security
and lastly..........reduce info redundancy
