"Although they're much less well known than different types, combinatorial maps are very robust info buildings and will be invaluable in lots of purposes, together with special effects and picture processing. The publication introduces those info buildings, describes algorithms and knowledge constructions linked to them, makes connections to different universal buildings, and demonstrates the way to use those constructions in geometric modeling and picture processing.

This is where all of the information regarding connections is stored. Using a DSN allows you to not worry about the actual definition of the connection string in your application. The details (such as the data-source type and location) are maintained by the ODBC applet on the system you are running your application. When using a DSN, ADO looks up the connection information through the ODBC applet. 1 Installing the DSNs Throughout the rest of this book, I will be using two DSNs. mdb database usually located in the C:\Program Files\Microsoft Visual Studio\VB98 directory when you install Visual Basic.
One of the more flexible features of ADO is that it can offer the developer data providerdefined functions that are not part of the standard ADO specification. For instance, the Microsoft Cursor Service for OLE DB offers dynamic properties that are used to specify how often calculated and aggregate columns are calculated within a data-shaping query. Instead of working with only the lowest common denominator in data-access techniques, ADO allows your application to check for and take advantage of functions that are specific to a particular data provider.
