Chapter 20. Distributed Applications with DataSnap

   

---

by Bob Swart

IN THIS CHAPTER

• Introduction to DataSnap

• DataSnap Clients and Servers

• Stateless DataSnap

• Deployment

In this chapter you will learn about DataSnap, the multitier database technology previously called Multitier Database Architecture Services (MIDAS).

Using a multitier database architecture, you can partition applications so that you can access data on a second machine (a database server) without having a full set of database tools on your local machine. It also enables you to centralize business rules and processes and distribute the processing load throughout the network.

The examples in this chapter use DataSnap, which means that you must have a copy of the Enterprise Edition of C++Builder to run the programs in this chapter. Note that you can also use the trial version of C++Builder 6 Enterprise to run the examples in this chapter.
