Teach Yourself e.net - Syspro

Getting Started with e.net solutions
Objectives - In this chapter we will introduce the basic structure of programming with
e.net solutions. We will demonstrate the capabilities of programs that interact with the
e.net solutions framework by using two different models: the Basic model, and the
Abstraction Model. By the end of this chapter you will have created your first program,
sending and receiving information from the SYSPRO application server through the e.net
solutions framework.
3.1. The Structure of Program
Having seen what SYSPRO e.net solutions is comprised of, and how SYSPRO is
accessible to COM and .NET programming through e.net solutions, we now turn our
attention to the concepts of programming that will access the e.net solutions framework.
Development of e.net solutions based applications requires the programmer or
development team to consider questions of programming organization and structure. As
we consider programming with e.net solutions, there are two development models that we
can use to define our development methods and application structure:
• The Basic Model
• The Abstraction Model
3.1.1. The Basic Model
The Basic Model is centered around the e.net solutions COM interface. As such it requires
that an application will, for each interaction with SYSPRO, call a method, a business
object if required, and pass/receive parameters or data as XML strings. The Basic Model,
while simple, enables rapid development of rich and fully functional applications.
Understanding of the Basic Model provides the foundation for developers that wish to
structure their application using the The Abstraction Model.
As with any application development, developers need to have a clear understanding of
their business's or customer's requirements in order to design an application that will
provide the required functionality. If this objective is clear, the basic structuring and
functionality of an e.net solutions application is easily described using Unified Modeling
Language (UML) Sequence-Diagramming.
The application shown in Figure 3.1, “Basic Program Structure” [3–3] illustrates the use
of the e.net solutions framework and business object components to create an application
