Chapter 1 Very Basic... Before venturing into the tasks you want to accomplish with ALLBASE/SQL, we give a bit of thought to some basic ideas, tasks, and concepts: * What is a database? * What is a relational database? * What is SQL? * What is ALLBASE/SQL? * What is a DBEnvironment? * How do I create a DBEnvironment? * How do I create a database? * How do I access a database? * How do I control database access? * Where can I get help with ALLBASE/SQL? SQL stands for Structured Query Language, which is defined by ANSI standards in the United States and by X/OPEN standards in Europe. In addition to standard SQL, ALLBASE/SQL uses some terminology of its own. A prime goal in this chapter is to provide you with a "working vocabulary" in both standard SQL terminology and the additions used by ALLBASE/SQL. If you already have this working vocabulary, skip ahead to the next chapter, "Looking at Data." Then come back here whenever you want to review the basics. You can also refer to the glossary in chapter 6 for definitions of basic terms.
