Things to be considered while designing a database

• The number of columns in the table must be reduced as much as can.
• The database must allow future enhancement i.e. any additional data required can be added without much difficulties.
• Instead of adding more columns, it is advisable to have more number of  tables ( even that too for a particular extent, since time for referring more no.of tables equals referring more no.of columns).
• In a developer's perspective, the database must be simple enough in order to make the coding simple. By doing so, the future changes might not have more effect on the code.

PROCESS ???

         Process in general can be understood as the task that is to be carried out to
meet our expectation. A Process needs some methodology to achieve that expectation. Regardless of whomever, achieving the expectation remains same if he or she follows same procedure.

        A process can be understood using the following example.

         Lets assume that you wanna cross a road. In this, crossing the road is our expectation. To meet this expectation we must ensure whether following questions are answered.

• Whether the road is free, else we need traffic police to assist - Ensures the support
• Whether we are going to cross - Ensuring the ability.
• What mode you are selecting either by walk, or you can take a bike - Activities
• How long the road is, How much time we are going to take for this and so on - Measure
• Which method would make you reach faster- optimizing    

     
        By answering all these, we can achieve our expectation and thus the process is done.
