Chapter 14, "Client/Server with dbExpress." I'll include an overview of the TDataSet class, an in-depth analysis of the TField components, and the use of data-aware controls. Chapter 14 follows up by providing information about more advanced database programming topics, particularly client/server programming with the use of the dbExpress library (and the InterBase Express components).
Finally, notice that almost everything discussed in this chapter is cross-platform. In particular, the examples can be ported to CLX and to Linux by recompiling and referring to CDS files in the proper folders.
