Release 10.1A: OpenEdge Getting Started:
Welcome to Release 10

OpenEdge Application Server

The OpenEdge Application Server provides advanced network deployment capabilities to help meet the processing demands of your distributed enterprise applications. Through application partitioning, the Application Server allows you to separate the business logic from the user interface in your network- or processing-intensive applications. There are two editions of the Application Server to cover the range of configurations a business might need: Basic Edition and Enterprise Edition. The components that compose the OpenEdge Application Server include the AppServer and WebSpeed Transaction Server. The AppServer encapsulates 4GL procedures into reusable code, allowing you to move your business logic from clients to faster servers distributed across the network. Features include stateless server technology, message queuing, an integrated NameServer, and support for multiple client platforms and asynchronous client requests. OpenEdge Studio includes development versions of the OpenEdge Application Server.

AppServer

The AppServer allows you to build and deploy complex distributed applications using the Progress 4GL. The AppServer allows you to initiate procedure requests from any location and run those procedures at another location. From OpenEdge, Java, .NET, or Web services clients, you can call and execute 4GL-based remote procedures on an AppServer. The AppServer offers load balancing, message queuing, stateless server technology, Java, .NET, and Web service access to the AppServer through a tool-generated proxy using an object-oriented protocol, and an integrated NameServer that directs client requests to available application brokers.

Clients can communicate with an AppServer over the Internet using an adapter that extends the functionality of a standard Web server. When using this adapter, all requests between a client and an AppServer are transparently encapsulated within HTTP. Tunneling AppServer requests through a Web server using HTTP/S provides the basis for secure, firewall-protected access to the AppServer over the Internet.

WebSpeed Transaction Server

The WebSpeed Transaction Server helps you build complete (D)HTML-based business applications for the Internet and corporate intranets. It includes transaction agents that run your WebSpeed application logic, transaction brokers that manage a pool of transaction agents, a messenger that allows you to distribute your WebSpeed application over a network, and powerful utilities that allow you to scale, define, and administer your WebSpeed Transaction Server. The WebSpeed Transaction Server is designed to allow you to rapidly develop and deploy high transaction processing, Web-based applications.
