Hi. I am looking for a technological solution of an embedded database with spatial data support to be used within a custom UDIG-based application as a single data storage (of simple features with geometries and other tabular metadata) with an ability for UDIG to work with feature layers through Geotools' DataStore API and having a direct connection to perform arbitrary CRUD operations with attribute data by SQL (preferably even through ORM interface).
From this point of view what is a state of recent development in H2 GeoDB? Base requirements are above; there is a need to query the data sets having 5000 - 25000 features (polygons) in general, of course, as fast as possible (spatial indexing is a MUST). All together I would consider this solution as a lightweight "version" of a File-based Geodatabase from ArcGIS platform (nothing complex beyond basic requirements above, again). Seems this functionality is important for us and in general for open source GIS (similar concept as file-based geodatabase of ArcGIS) in order to handle as spatial as non-spatial data together locally with direct SQL access and other interfaces, instead of old-fashion set of shapefiles with their data type and other constraints, so, we are ready at some point to invest to the development and contribute new features to the community. But, what is a current state of H2 GeoDB and Geotools' H2 DataStore implementation, what are other possible alternatives of an embedded Java SQL database with spatial support? An idea of an "embedded" database is there because we need to provide a solution to be deployed somewhere locally in offline on desktops, shouldn't require any complex configuration, must be simple by nature, better, ifit isjust supplied within a single package (UDIG -based app), etc... So, in ArcGIS I would use some type of geodatabase. What to choose and where to invest in UDIG + GeoTools ecosystem?
