Relational Data Base Management Systems (RDBMS) are database management systems that maintain data records and indices in tables. Relationships may be created and maintained across and among the data and tables. In a relational database, relationships between data items are expressed by means of tables.

In SQL Server, there are two kinds of indexes – clustered and non-clustered. Clustered Indexes require that the data in the table is physically sorted in the order of the index.

Using a delegate allows the programmer to encapsulate a reference to a method inside a delegate object.
