Recital implements SQL-92 and most of the SQL-99 standard for SQL, but also provides lower level navigational data access for performing high transaction throughput. It is the choice of the application developer whether to use SQL, navigational data access, or a combination of both depending upon the type of application being developed.
The best way to learn Recital is to build some applications. The developers of Recital have written a book "Recital Essentials" which you can read here.
In this article Barry Mavin, CEO and Chief Software Architect for Recital debunks the myths and misrepresentations surrounding XBase and explains how Recital, an enterprise-class XBase platform, has overcome all the shortfalls and weaknesses of early XBase implementations.

There is a good article here this describes agile software development techniques. This is what we have always been doing but it's nice to see it defined formally.
We use this technique ourselves on our development portal.
