What are commonly used database types? There are a lot of database types. Can you list a list of the top classification of databases commonly found in schools and offices? Any help is appreciated. Hope to see compressed and summarized type as possible.
Take a look at this list of mine :


Employee/ Student Information
Account Receivable/Payable
Attendance Record
Inventory
Class/Task Records


Hope this list helps. For further reference, you can try to look at this : http://www.techyv.com/article/most-used-database
