<hr/><a name="_details"></a><h2>Detailed Description</h2>
<div class="textblock"><p>Dictionary object. </p>
<p>Previous versions of Libgda relied on an XML based file to store dictionary information, such as the database's schema (tables, views, etc) and various other information. The problems were that it was difficult for an application to integrate its own data into the dictionary and that there were some performances problems as the XML file needed to be parsed (and converted into its own in-memory structure) before any data could be read out of it.</p>
<p>The new dictionary now relies on a database structure to store its data (see the database schema section for a detailled description). The actual database can be a single file (using an SQLite database), an entirely in memory database (also using an SQLite database), or a more conventional backend such as a PostgreSQL database for a shared dictionary on a server. </p>
