Object Interconnections Comparing Alternative Client - side Distributed Programming Techniques

This month’s column examines and evaluates various programming techniques for developing distributed applications. Our previous column outlined the requirements for a representative distributed application in the financial services domain. This application enables investment brokers to query the price of a stock, as well as to buy shares of stock. As shown in Figure 1, the quote service that maintains the current stock prices is physically remote from brokers, who work in geographically distributed sites. Therefore, our application must work efficiently, robustly, and securely across various wide area (WAN) and local area (LAN) networks.
