Explanation / Answer
Answer:
First order predictive knowledge.
To improve predictive knowledge 'First order predictive logic' is used but for a good database design it is never used in business as it deal with certainty and uncertainty based on data stored/historical data.It is used in artificial intelligence to improve predictive accuracy.
Tables in design are constructed properly and efficiently:
Of cource for any database design it is important to design and construct the table properly.The complete structure should be clear at the time of desgning and most importantly the way we can modify and change schema based on future requirement.Suppose if you have a relation database with five fields and in future if you need to add one more fields then how it will effect the other data stored in table.
Logic is used in arranging the management system:
It is also the most important part of database designing.How one table is related with other (e.g. - with the help of foreign key) and what fields should be in common to access the data.How the logic of join can be implemented to fetch the data.Of cource the primary key should be decided very carefully.
Restrict use of the database system.
Database design never restrict the use of database system however it has restriction over how it is used.
