Now, lets join me!!
For this time, I will comment about chapter 7..what is the interesting part of this chapter??
That is DATABASE.. what is the use of database??database is a place that information is saved..by having database, the information can be protect and it will help us to find the data..
However, we have to make sure that the information is not redundant, if not there will have a problem to us to identify the information...
In database, there is a column and raw to differentiated between ENTITY and ATTRIBUTES..In order to manage and organize various entity classes, there must have a PRIMARY KEY..that is a field ( group or fields ) that uniquely identifies a given entity in a table..
Having a database, it will give an advantages to the user, such as increased flexibility, increased information security, reduced information redundancy and many more..
Now, I aware t\hat database is a system that provided to us to make an information more accurate and complete...
That's all...we will meet again...
