    Another great post! I’m working on migrating my career from a traditional GIS Analyst to become a Database Administrator and the biggest hurdle is the huge learning curve to become a DBA. It’s not that being a DBA is difficult but, there is a very wide spectrum to being a DBA just like in GIS. Some DBA’s are purely administrators, some Developers, some just concentrate on performance tuning however, I feel that to be a good GIS DBA, you really need to be a jack of all trades and have the GIS understanding on top of the DBA skill set. The other thing you will find in the DBA world, is that very few people understand or work with spatial data and certainly not ArcSDE and this is where many traditional DBA’s fall short when it comes to administering geodatabases.

    Justin,
    Here are my quick thoughts:

    1. To be be a spatial database administrator, the preliminary skills set required are relational algebra, SQL , and Computational Geometry on top of GIS. Literally, CS graduates are taught for relational algebra and SQL and later one they cope up with adding spatial skills on top of it.
    2. Without understanding RDBMS and modern database system, its quite weird to stay on top of it and talk about spatial database only. Hence, I strongly recommend geography majors to think seriously about database design by taking course in CS department and information system department. Either database design course or database application course can help to solidify the skills required to be database specialist.
    3.I recommend PostgreSQL/PostGIS and MySQl to understand the broader aspect of the spatial database.
