3. What will we learn?

4. Database Prehistory Data entry Storage and retrieval Query processing
Sorting

5. Early Automation
Data management and application code were all tangled together
Hard to modify
Hard to generalize
Many competing approaches
Data manipulation code written at very low levels of abstraction

6. Our Hero --- E. F. Codd
Edgar F. "Ted" Codd ( August 23, April 18, 2003) was a British computer scientist who invented relational databases while working for IBM.
He was born in Portland, Dorset, studied maths
and chemistry at Oxford. He was a pilot in the
Royal Air Force during WWII. In 1948 he joined IBM
in New York as a mathematical programmer. He fled
the USA to Canada during the McCarthy period.
Later, he returned to the USA to earn a doctorate in CS
from the University of Michigan in Ann Arbor. He then
joined IBM research in San Jose.
His 1970 paper “A Relational Model of Data for
Large Shared Data Banks” changed everything.
In the mid 1990’s he coined the term OLAP.

7. Database Management Systems (DBMSs)
Database abstractions
allow this interface to
be cleanly defined and
this allows applications
and data management
systems to be
implemented
separately.

9. What is a database system?
A database is a large, integrated collection of data
A database contains a model of something!
A database management system (DBMS) is a software system designed to store, manage and facilitate access to the database

10. What does a database system do?
Manages Very Large Amounts of Data
Supports efficient access to Very Large Amounts of Data
Supports concurrent access to Very Large Amounts of Data
Supports secure, atomic access to Very Large Amounts of Data

11. What this course is about
According to Ullman, there are three aspects to studying databases:
Modelling and design of databases
Programming
DBMS implementation
This course addresses 1 and 2
