Lecturer at the University Institute of Technology University of Paris 13, when the price of
Databases I was given , I had to search through the voluminous literature on Databases
an appropriate course material. The literature on properly designing databases, using the entity-relationship model, are not so numerous and often date from the time Merise

. In addition to the design, I wanted to address the relational algebra and SQL, and finally triggers. Each of these parts should be punctuated with workouts in the form of tutorials or practical work. So I started writing a custom course material, which, Revision revision, this book became
published in the collection Info + Editions Ellipses as the Databases - from modeling to SQL
. This book of 255 pages consists of 5 chapters described below.

Introduction to Databases -

The objective of this short chapter is to introduce the issue of databases: definition of the concept of databases, models of databases, management systems Databases (DBMS).

Design of databases: the entity-relationship model - This chapter explains how properly design a database. After describing the components of the entity-relationship model, the notion of type-association is detailed, then a range of methodological rules it is useful to apply to obtain a well-trained model is then presented. The problem of standardization-type-type entities and associations are then addressed before discussing the appropriateness of type-n-ary associations. relational data model - This chapter begins with a presentation of the relational model, then describes the way to spend an entity-relationship model a relational model. The theory of normalization, which is a valuable tool to flush out the redundancy in the databases is then presented in detail. The last chapter discusses the relational algebra which is the formalism supporting the query language SQL. Language SQL - This chapter is entirely devoted to the SQL language that is considered the language of standardized access to relational databases. The creation and manipulation of the structure of the database are processed first. SQL commands to insert, delete and modify data then discussed. Then, two sections are devoted entirely to the command to query a database. The last section focuses on the description of some particular objects. SQL Programming -
The purpose of this chapter is to present how to combine basic SQL commands with a programming language. The first objective is the implementation of complex functionality in the DBMS with the user functions. These functions are then used to implement complex and dynamic behavior by using the mechanism triggers, making the current database.

The second objective is the interaction between a program and DBMS addressed by describing how to embed SQL commands in a program written in C.
