Database 1
Data Manipulation
Prof. dr. Paul M.E. De Bra

Notes:
In this second track of the course Databases 1 we study data manipulation.
With data manipulation we mean all operations on the data in the database. This includes the addition of new information, removal of information and modifications, or updates as we call them. But what we are most concerned with in this course is the retrieval of information. You can study insertions, deletions and updates in the database book, but we are going to concentrate on querying or asking questions to a database.
