EATSv5 is constructed as an Eclipse RCP product. The initial build for EATSv5_2020 was accomplished by generally following the narrative1See Annotated Vogella Tutorial provided in the Vogella tutorial Eclipse RCP (Rich Client Platform) – Tutorial.
EATSv5 is an Eclipse application which operates as a plug-in in an Eclipse RT (Equinox) virtual machine environment. Eclipse RT is a Java framework suitable to support either or both development and production operation. It supports deployment of the same application to Windows, Unix, Linus, Mac and Android operating systems via substitution and packaging of libraries which map standard JVM to OS and hardware specific code layers. Eclipse also supports integration of desktop and web-based interaction from a single deployed instance.
