postGIS vs. TAB files

[Bart van den Eijnden]

One problem of the TAB support through OGR currently is that the attribute indexes are not being used. So doing queries on large TAB files is not that fast.

Best regards,
Bart

Hi David

We use TAB a lot and do not really see too much difference to Shape. To
me it performs similar to PostGIS. But as Paul says: "but in general
PostGIS is more effective if you want to consolidate management of data
into one place, query/modify the data from multiple applications/
clients, and get better optimization of composite spatial/attribute
queries". TAB is good for "display and query" kind of applications ...

Mit freundlichem Gruss / Best Regards
