Structured Query Language, SQL, is the de
facto standard for accessing relational DBs.
– SQL is a high-level language that provide a greater
degree of abstraction than do traditional procedural
languages.
– SQL is designed such that programmers specify what
data is needed.
– SQL is coded without embedded data-navigational
instructions.
• The DBMS analyzes each SQL Statement and
formulates data-navigational instructions
“behind the scenes.”
