then what is the difference between DBMS and a programming language compiler?

1. it has to deal with data stored in hierarchical memory structures

then what is the difference between DBMS and a programming language compiler?

2. it has to support efficient manipulations of data in hierarchical memory structures

3. it needs to translate the input database program into an internal representation
