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

DDLlanguage
database programmer
DML (query)language
then what is the difference between DBMS and a programming language compiler?
1. it has to deal with data stored in hierarchical memory structures
DBMS
file manager
buffermanager
mainmemorybuffers
secondarystorage(disks)
in tables(relations)
databaseadministrator
DDLlanguage
database programmer
DML (query)language
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
DBMS
file manager
buffermanager
mainmemorybuffers
index/file manager
secondarystorage(disks)
in tables(relations)
databaseadministrator
DDLlanguage
database programmer
DML (query)language
then what is the difference between DBMS and a programming language compiler?
3. it needs to translate the input database program into an internal representation

then what is the difference between DBMS and a programming language compiler?
4. it needs to produce efficient internal codes dealing with data in hierarchical memory structure
DBMS

then what is the difference between DBMS and a programming language compiler?
5. it needs to be consistent
DBMS

DDL complier
query execution
engine
transaction manager
concurrency control
lock table
secondarystorage(disks)

then what is the difference between DBMS and a programming language compiler?
6. it needs to be reliable
