To connect an Access database (.accdb file) from a C# application, you need to download and install the 2007 Office System Driver from Microsoft. This will allow you to connect to and query the Access database. A database stores data in an organized, structured format using tables. Tables contain rows and columns to hold related data. The SQL language is used to query and manage databases and tables using commands like SELECT, INSERT, UPDATE, and DELETE.

5. Creating a table
 Table?
 A table is a structure that holds relational data in
rows and columns.
 Rows hold data and columns hold types.
 Column count is constant but row count is
variable.
 Every table stands for an entity. So for each entity
we will need another table.

6. Tree rules in table design
 Divide data into smallest pieces.
 Don’t try to store two different data in one
place.
 Make sure that you will be able to separate
data from another.
