	Calc	A spreadsheet similar to Microsoft Excel and Lotus 1-2-3. Calc can export spreadsheets to the PDF format. (See ooWriter entry, above, for details of PDF). Calc provides a number of features not present in Excel, including a system which automatically defines series for graphing, based on the layout of the user’s data.

Impress lacks ready-made presentation designs but this can be overcome by downloading free templates on-line.[42][43]
	Base	A database management program similar to Microsoft Access. Base allows the creation and manipulation of databases, and the building of forms and reports to provide easy access to data for end-users. As with MS Access, Base can function as a front-end to a number of different database systems, including Access databases (JET), ODBC data sources and MySQL/PostgreSQL. Base became part of the suite starting with version 2.0. Native to the OpenOffice.org suite is an adaptation of HSQL. While Base can be a front-end for any of the databases listed, there is no need to install any of them. Raw SQL code can be entered by those who prefer it, or graphical user interfaces can be used.

It features versatile "connectors" between shapes, which are available in a range of line styles and facilitate building drawings such asflowcharts. It has similar features to desktop-publishing software such as Scribus and Microsoft Publisher. Draw can also export its creations to the PDF format. (See ooWriter entry, above, for details of PDF).
	Math	A tool for creating and editing mathematical formulae, similar to Microsoft Equation Editor. OOo users can embed formulae inside other OpenOffice.org documents, such as those created by Writer. It supports multiple fonts and can export to PDF.
