MySQL Definition

Pronounced Òmy ess cue elÓ (each letter separately) and not "my SEE kwill." MySQL is an open source RDBMS that relies on SQL for processing the data in the database. MySQL provides APIs for the languages C, C++, Eiffel, Java, Perl, PHP and Python.

In addition, OLE DB and ODBC providers exist for MySQL data connection in the Microsoft environment. A MySQL .NET Native Provider is also available, which allows native MySQL to .NET access without the need for OLE DB. MySQL is most commonly used for Web applications and for embedded applications and has become a popular alternative to proprietary database systems because of its speed and reliability. MySQL can run on UNIX, Windows Vista and Mac OS.

SQL Definition

Structured Query Language. Developed by IBM in the mid-1970s as a way to get information into and out of relational database management systems. A fundamental difference between SQL and standard programming languages is that SQL is declarative. You specify what kind of data you want from the database; the RDBMS is responsible for figuring out how to retrieve it. I include a tutorial on SQL in the chapter "Database Management Systems".

Visual Basic Definition

Visual Basic (VB) is a programming environment from Microsoft in which a programmer uses a graphical user interface to choose and modify preselected sections of code written in the BASIC programming language.

Since Visual Basic is easy to learn and fast to write code with, it's sometimes used to prototype an application that will later be written in a more difficult but efficient language. Visual Basic is also widely used to write working programs. Microsoft says that there are at least 3 million developers using Visual Basic.
