Prototyping an ABAP OData Entity Data Model Generator: Preparing EDMX XML

Continued from my previous post "Prototyping an ABAP OData Entity Data Model Generator : Table Relationships" :

I’ll now write about the EDMX/CSDL preparation part and completed prototype program. Finally, we’ll do a few test runs to generate edmx/xml files and see how it looks when imported into Eclipse data-modelling plug-in.

Prototyping an ABAP OData Entity Data Model Generator : Table Relationships

Moving further from first part of this application, explained in my previous post Prototyping an ABAP OData Entity Data Model Generator : Simple Transformation, I’ve now put together some details about the main ABAP executable program.
...Continued from previous post

So we now have the simple transformation program in place and next step is to develop an ABAP executable program that will take header/main database table name as input, fetch details of table meta-data/foreign-key relationships, populate a variable of type structure ZRAM_EDMX_CSDL_SCHEMA using selected data and then finally use "call transformation" to convert data to XML. I'll write about this prototype program....

Prototyping an ABAP OData Entity Data Model Generator : Simple Transformation

As mentioned in my earlier post It's the best of times, I’ve been trying to auto-generate the entity service-data-model XML ( EDMX file ) from exiting SAP database tables and their relationships.

Background:

SAP NetWeaver Gateway Service Builder (transaction SEGW) is a design-time environment to support creation of OData Services. It provides several options to support both, Outside-in and inside-out service Development Approaches:

Netweaver Gateway Services: oData Query Builder - A Prototype

As mentioned in my earlier post It's the best of times, I've put together some technical details of an ABAP BSP application. The application will use the generic "oData Query Builder" that is available as open-source at oData Website.

Summary:

I liked this open source oData Query builder ( see a demo here ) so I embedded this utility into a BSP application to enable simple exploration/testing of SAP Gateway oData Services ( only GET/Query part). Additional changes are made in ABAP BSP application to fetch all the active oData Gateway services with corresponding URLs from the SAP system and populate the endpoint drop-down. Rest of the functionality is pretty much as provided by the oData Query Builder library.

It is the best of times..

..hopefully.

Last month I quit CGI/Logica to start my own SAP Consultancy and solution development company, PragmatiQa Ltd. Obviously it was a difficult decision to quit Logica after nearly 10 years of my association with the company. The reputation, relationships and comfort zone not to mention the job-security, monthly paychecks and the important one - especially for a person with parental responsibility - the flexibility of working from home. Interestingly, you can actually think of quite a few nice words for your day-job, once you start thinking about quitting it :)

But like every software developer who opts for a career in software development for the passion and not merely as a stepping stone for a managerial / leadership positions in a big company or as a starting point of upward organizational hierarchy traversal mechanism :) - I too had a dream of taking the plunge - one fine day.
