Wassim: You may also consider ContentDataStore tutorial <https://docs.geotools.org/stable/userguide/tutorial/datastore/index.html> which introduces the DataStore API - and importantly the helper classes available to implementers.
The JDBCDataStore builds on this work (isolating most database specific decisions into a dialect class as you have seen). -- Jody Garnett On Thu, May 18, 2023 at 4:32 AM WaZy <snaele...@gmail.com> wrote: > If I follow the "tutorial" written in the text file jdbc-notes.txt will it > help me to achieve what I want ? > > I have also already started to take a look at the code of the PostGIS JDBC > plugin, but I find it a bit hard to understand because there are some > functions where there are details that are not explained.
