I am looking for GIS DB, to work with 800 millions of GIS data. I want to make my work more simple easy by doing it in spatial DB. I want to work with Geography and not on Geometry. Please suggest some good and easy to understand the db. I use MAPINFO for mapping.

    Welcome to GIS-SE. As a new user it is recommended to take the tour which will guide you about Q&A here. Please edit your question provide more data on what you are going to perform. What do you mean by working on Geography? What do you need beyond what MapInfo can provide, etc. – dof1985 Jul 27 '16 at 7:10

  • What do you mean by work with 800 millions of GIS data? Millions of what? – nmtoken Jul 27 '16 at 8:07
  • "Simple easy" and 800 million rows are inherently incompatible. As soo as you enter the realm of large data (roughly over 20-40m tows), nothing is easy. – Vince Jul 27 '16 at 12:38

You can use PostgreSQL, MS SQL server Express or Oracle XE. They are all free, but the two latter are restricted in terms of how much data they can work with. 800 million records of some datatype may be too much for them (?). In that case go with PostGreSQL. All 3 of them can be directly accessed from MapInfo.
