Robyn,
Putting your company's data in a database is a long-term committment. Aside
from technical and financial considerations, think about:
- How long is this vendor going to be around?
- How easy is it to hire people who are experienced in this database?
- How many books, web sites, discussion lists, training classes, etc.
are available for this database?
