It is becoming less possible for developers of integrated software solutions to quickly, efficiently, and inexpensively develop all of the functions and modules desire by actual users in the industries. The requirements can be achieved by reusing existing software components. The principle of component software is already changing the software development concept. The proposed tool provides a programming environment for ERP development in 3-tier solution. It provides the entire system implementation cycle with tools for modeling, programming in the 4GL language, definition of data and table structures, and the design of graphical user interfaces. As a supplement to the development tool, SEA+ delivers a template library for the design and manufacturing and components that can be incorporated into custom functions.
