<div class="moz-cite-prefix">I don't know all the reasons for Access
Geodatabases but here is what I do know. <br>
<br>
When ArcINFO started turning into the desktop product there was a
move to get things into a "database". ESRI had used INFO/Coverages
for years. I think the quickest way to get to that end was Access.
You could fold all your vector data into Access. It is slow from
ArcGIS. You can't store raster. It has the habit of becoming very
large very quickly and imploding. I think somewhere between 500Mb
and 2 Gb were the problem sizes. They introduced file based
geodatabases which aren't databases and aren't file based - they
are directories and in my opinion are coverages Part II. File
based databases are stable and much easier to work with - and too
proprietary for my tastes now. You can get the data out but it
isn't easy. <br>

I think to hold files in a directory (folder) are a very sheep
price compared to slow performance limited storage to max 2 GB.<br>
<br>
Does anyone know if there may be other problems with MS Access
files? Missed seached data and so on?<br>

Okey. I'm new to database use i GIS and have only used
file database that<br>
ESRI recommend. But if mdb are a propretarian and only
work well with MS<br>
access, how can it then be highly portable?<br>
<br>

I thought of "portable" in the sense of taking a database from
one computer to another. MDB and sqlite are just one file,
Shapefile a couple of files, and PostgreSQL/Postgis is very
complicated to share/take with you or make a security copy.<br>
