Architecture overview

The architecture of the Brazil Suite is the same as the Infor LN architecture. The guest OS of the suite is Windows or UNIX. The LN Runtime is the portingset, which connects the database to the OS. The LN Platform is the Enterprise Server, which provides the tools that allow the application to send queries to and receive the result from the database. The LN Application is the Brazil Suite.

This diagram shows the platform that the Brazil Suite runs on:

In general, the Infor LN architecture contains these layers:

Layer	Component
Presentation	Infor Windows (WebTop) or Infor web UI
Application	Infor LN Virtual Machine The most important component is the bshell, which works as an interpreter on the Infor LN objects. These Infor LN objects contain the compiled Infor LN 4GL code of the programs. The bshell interprets the 4GL code and can be seen as the engine behind the presentation layer. The bshell sends display information to the presentation layer and receives user response from it. On the other side, it has a connection to the database layer where it sends queries to and receives the results.
Database	Each supported database has a driver. This component, known as the database driver, is the most important part of the database layer. The database driver transforms the Infor LN queries into database-dependent queries and takes care of the communication between database and application layer.
