Does SQL Azure have Allure?

Mar 262010

image I love SQL Server 2008 spatial functionality. Not only because it has effectively killed off the middle-man GIS database software, but it even sticks to OGC standards allowing the same data and tables to be used in nearly all GIS software. However I have some reservations about the use of SQL Azure for GIS applications.

FAQ

How is SQL Azure Database different from working with a hoster using SQL Server?

Developers do not have to install, setup, patch or manage any software. High Availability and fault tolerance is built-in and no physical administration of hardware, storage or servers is required.

If you have a good hosting solution then the same benefits apply (well maybe not the “self-healing” also mentioned). The only real difference I can tell is that you pay a lot more, to be able to scale more easily. Its unlikely your Local Planning Mapping system is suddenly going to need to scale up to meet the expectations of millions of new users, no matter how great the system looks.

For a new project I am working for the first time with MapInfo 10 “the world’s premier desktop mapping application.”

In an effort to move away from MapInfo’s .tab files (the shapefile equivalent) I was keen to test out the direct connection to geometry stored in SQL Server 2008. Until version 9.5 data could only be stored and accessed in a relational database using SpatialWare. Again to use ESRI terminology this is the ArcSDE equivalent. Fortunately MapInfo was quick off the mark in removing this barrier.

Access to SQL Server 2008 spatial data is provided by integrating FME functionality directly into the product, and having a “Universal Data” option on the File menu. There is also a tool named Easy Loader that allows loading .tab files into SQL Server as geometry.
