How a Database Organized? Access holds its information in tables. A table is one of a number of “database objects” that are used in Microsoft Access.

Tables Tables are the foundation of an Access database. Access stores data in tables. A table is a set of columns and rows. Each column is called a field. Within a table, each field must be given a name and no two fields can have the same name. Each value in a field represents a single category of data. Each row in a table is called a record. The records consist of ‘fields’, contained in the columns, each holding one piece of data about the record. Fields can contain different data types, such as alphabetical, numerical, date/time, yes/no. MS access
