Base comes configured with the full HSQL relational database engine. It's an ideal solution for everyday jobs, and for people requiring an easy-to-understand, simple-to-use system: data is stored right inside the Base file, and you also get native support for dBase flat files. LibreOffice Base provides wizards to help users who are new to database design (or just new to the software) to create tables, queries, forms and reports, and it comes supplied with a set of pre-defined table definitions for tracking assets, customers, sales orders, invoices and many other common and useful items.

Base is much more than a tool that can be used for standalone purposes – it's also perfectly integrated with LibreOffice's other applications. Base can supply address book data for mail merges in Writer using the LDAP protocol, or various address book formats. In addition, Base can be used for creating linked data ranges in Calc files, for data pilot analysis or as the basis for charts.
