A map datum is a reference from which measurements are made.
In geodesy, a geodetic or map datum is a set of reference points on the earth's surface against which position measurements are made, and (often) an associated model of the shape of the earth (reference ellipsoid) to define a geographic coordinate system.
Some examples of geodetic datums are: NAD27, NAD83, ED50 etc...
An map datum can be defined in the Eye4Software Coordinate Calculator or Eye4Software GPS Toolkit using 7 parameters, also called Helmert-7 parameters:

Using the Eye4Software Coordinate Calculator, you can convert coordinates from one map datum to another easily, using the user friendly user interface. This software is shipped with a database containing allmost any map datum, reference ellipsoid and map grid around.
Using the Eye4Software GPS Toolkit which is a GPS SDK (Software Developer Kit), you will be able to add coordinate conversions to your own software, scripts or webpages in the blink of an eye.
The SDK can be used with various programming environments including: Visual Basic, Visual C++, Visual Basic .NET, Visual C# .NET, VB Script, Borland Delphi, Borland C++ Builder, VBA (Access and Excel) and more.
