Chapter 1. DBMS Specifics
You need a database management system to run SQL programs. You can have your own private copy of a DBMS running on your desktop (local) computer, or you can use a shared DBMS over a network. In the latter case, you use your desktop computer to connect to a DBMS server running on another machine. The computer where the DBMS is running is called a host. Because this book is about SQL and not DBMSes, I won't rehash the instructions for installing and configuring database software. This evasion might seem like a brush-off at first glance, but setting up a DBMS varies greatly by vendor, product, version, edition, and operating system. All DBMSes come with extensive installation, administration, reference, and tutorial documentation. (To give you an idea, just the installation manual for Oracle runs over 300 pages.) |
