About this course

At the end of this course you will:
You will understand the tasks which need to be considered and completed in order to migrate embedded business logic from thick client applications into OpenROAD Server compliant 4GL Procedures.  Additionally, the provision of the client side JSON-RPC request/response syntax is discussed and demonstrated to facilitate the calling of the appropriate OpenROAD Server based 4GL procedure or 'service'.
 
To be clear - in this course we are providing strategies that you will need to consider when undertaking a migration of this type.  Within your own organisation and application development teams you are likely to have your own processes for completing a task such as this but after watching the lessons within this course you will understand what is required and be able to plan out your own project accordingly.
Course Style:
The course lessons are informational and how to in nature.  For a first sitting, each lesson must be watched in the sequence presented to ensure the process described is understood.  Beyond this please watch the lessons as you wish.
