I quote for you 

 

 

To implement a database solution according to OGC standard the developers have to deal with:

  • Data types. There needs to be data types to store the GIS information.

  • Operations. There must be functions to support the management of GIS objects.

  • The ability to input and output GIS data. To make systems interoperable, OGC has specified how contents of GIS objects are represented in binary and text format.

  • Indexing of spatial data. To use the different operators, some means of indexing of GIS data is needed.

  • There is also a need for GIS metadata management and for using different coordinate systems.

 

PostGIS already support OGC standard
