Welcome to thePostgres Pro Tutorial. The following few chapters are intended to give a simple introduction toPostgres Pro, relational database concepts, and the SQL language to those who are new to any one of these aspects. We only assume some general knowledge about how to use computers. No particular Unix or programming experience is required. This part is mainly intended to give you some hands-on experience with important aspects of thePostgres Pro system. It makes no attempt to be a complete or thorough treatment of the topics it covers.

After you have worked through this tutorial you might want to move on to readingPart II to gain a more formal knowledge of the SQL language, orPart IV for information about developing applications forPostgres Pro. When learning SQL, you can use the demo database described inAppendix M. Those who set up and manage their own server should also readPart III.
