An Ingres table contains columns for each type of data and rows with all the information for each entry in the table. The following table shows data about customers:

Each item in the top row (for example, Name) is the title of a column. Each row under it provides information about one customer.

The user of an application usually needs to access one or more tables to look up information or manipulate the data (that is, add, delete, or change the data). A typical application displays table information and allows the user to choose the kind of data manipulation required.
