A database is an organized collection of data and programs used to manage that data, known as a database management system. Access 2007 databases use the .ACCDB file extension and most modern database management systems store and manage information using the relational database model, where data is organized into tables. Common database objects in Access 2007 include tables to store data, queries to extract and filter data, forms for data entry and display, reports to print data, macros to automate tasks, and modules to add custom programming logic.
