The Development Process

Development Process

 

To build a Host Integrator application, use the following steps:

  1. Plan your integration project

    To create a good model of a host application you must have a basic understanding of the business problem that you want the model to solve. There are guidelines available to help you plan your project in Planning the Project.

  2. Create and deploy the host application model

    There are a few steps you must follow to create and deploy a model.

    1. Navigate through the host application, identifying the screens and fields that lead to the data that you want to integrate into the new Web or client/server application.

    2. Expose the resulting components as database tables and procedures. A table is a database abstraction with attributes or recordset fields structured in table columns. You can create a procedure that defines how Host Integrator locates, retrieves, updates, inserts, or deletes the data when it fulfills a request through SQL or through another API. If you want to add functionality beyond what is provided in the Design Tool, you can add event handlers that extend or override default model behavior.

    3. Test your model to confirm that it operaties as you expect.

    4. Deploy the model to a folder containing the .model file and any supporting files on the Host Integrator server.

  3. Build a new Web or client/server application

    You can build a new application using these options:

  4. Deploy the application to the enterprise

    In a production environment, the deployed Host Integrator servers provide dynamic load balancing and failover in transaction-intensive environments. Host Integrator supports all mainframe-based security packages and also has its own multi-level security, which can be tied to the security schema of the selected deployment platform (Windows 2000, Windows XP, Windows Server 2003, UNIX, or Linux).
