# Part I. Tutorial

Welcome to the Postgres Pro Tutorial. The following few chapters are intended to give a simple introduction to Postgres 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 the Postgres 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 reading Part II to gain a more formal knowledge of the SQL language, or Part IV for information about developing applications for Postgres Pro. Those who set up and manage their own server should also read Part III.
