how to create a Professional table in Sql Server database

Hi,

I explain some rules which are support database efficiency.

Do not use system variables names for tables, columns, functions and stored procedure
Use database object in queries (dbo.tablename)
Use appropriate constraints ( Primary key, foreign key, Unique key)
Set proper indexing
Give meaning full name
Separate table it names itself in two ways for Master table and Transaction tables (like mst_Departments, trn_MonthSalary)
Your tables should be normalized
Primary columns must be integer type
