COndirional logic applied to the resules of the first SQL statements determines which subsequent SQL statements are executed. If there SQL statements and conditional logic are written into a stored procedure, In The Server, All of the Work Is Done The Consults Do Not Have. The result
2. Normalized database, if not, the database will have lots of redundant data.3. Over-normalize has no good for performance issue If a database is over-normalized, ie the database is defined with numerous small, interrelated tables, database performance is reduced. This is because when teh database processes the data in numerous, small and interrelated tables, it has to combine the related data, which results in an increase in teh database's workload. in these situations, denormalizing the database slighly to simplify complex processes Can IMPROVE Performance.
