Just a general question. If you have an application with different
data types where it might be better to use one database over another,
are there issues with having multiple databases used by the
application?
No, you can usuially have multiple databases open at once.
You can have multiple instances of the same database or
different database types.
However the data types are rarely ta reason to use different databases.
More typically would be different performance requirements or security
issues. For example it's common to hold some data in an LDAP structure
for speed of access (at the expense of flexibility) and the rest of the
data in an RDBMS such as MySql. But using say MySQL and Oracle together
would normally only be done because they were pre-existing datastores
from another project.
Thanks! I was more thinking of something like a CMS where user login
information and admin functions might be in a SQLite database and then
some larger backend big data stuff in MongoDB or similar. Just wasn't
sure if there was a basic flaw to the idea that I wasn't aware of.
Seems like a good idea. Right tool for right purpose.
