While the systems of both companies had their similarities, their implementations differed greatly. Intentia's M3 system was centered around a server-side Java business logic tier, which was accessed by a number of different client applications. Intentia's client user interfaces (UIs) had progressed over the years, starting with a MicroFocus Cobol/C++ rich client, progressing through Active Server Pages (ASP) and JavaServer Pages (JSP) based thin client solutions to an AJAX/JSP based thin client portal, known as the Workplace Foundation. The Lawson S3 application suite is a mix of Java-based and 4th Generation Language (4GL)-based solutions, but is evolving to pure Java-based in a similar overall fashion. Between the two companies, a number of different client technologies were being utilized, ranging from the Workplace Foundation web portal to a C# based mobile sales rich client.
