2 Definition It is a database platform used to create Database for.Net languages. It is based on Microsoft SQL Server It is a database platform used to create Database for.Net languages. It is based on Microsoft SQL Server 2005.

3 Database A file structured for the repository of data. Organized for easy retrieval, sorting, grouping, relating to other data, etc. Excel is also a flat database but lakes relations SQL is RDMS (Relational Database Management System) A file structured for the repository of data. Organized for easy retrieval, sorting, grouping, relating to other data, etc. Excel is also a flat database but lakes relations SQL is RDMS (Relational Database Management System)

4 RDMS Data is organized into tables that can be related together, thus reducing redundancy and increasing the integrity of data.

5 Normalization The process of determining what information belongs in which table to minimize redundancy and increase integrity.

6 Data Integrity Keeping a data Valid or Correct

7 Key and Identity Column Primary Key: A field or combination of fields that makes a given row unique in the database. A way of differentiating each row in a table when all other field might be duplicated in other rows in the same table. Key relates two tables to each other. Foreign keys relate one or more rows in one table to a record in another table that shares the same value in its primary key. Foreign key constraints enforce “Referential Integrity” Identity Column is an attribute that will automatically increment a field of data in each successive row added to the database. Typically used on primary key field to make them unique. Primary Key: A field or combination of fields that makes a given row unique in the database.
