Introduction
You are on the personal site of Marc
Grange.
Information appearing in these pages concerns all people wanting
to apply and use the techniques of databases. Various examples are
taken from the field of Social Sciences, but the SQL language training
and the databases design method presented hereafter, relate to all
the fields that imply an effective management of data.
Practitioner, developer and teacher, I use and teach databases for
more than 20 years.
Prerequisites
Knowledge on Databases design, the relational data
model and SQL language are essential to follow this presentation.
The reader not having required knowledge, but wishing to approach
these various fields, can refer, in these pages, at the columns

Objective
The aim of this presentation is to show some interesting
applications of Databases in Humanities and Social Sciences. The
use of a data model to structure information, here the relational
model, allows then to work with SQL language for the extraction
and production of relevant information relating to the studied field.
This "generic" approach, which uses the properties of
DBMS (DataBases Management Systems),
avoids the development of specific application software developments.
Four examples, in connexion with Humanities and Social Sciences
, will be successively presented :
|
- In Sociology
|
|
|
- In Demography
|
|
|
- In Psychology
|
|
|
- In Geography
|
|
Each example will be treated according
to the following steps :
-
Presentation of the data connected to the problem
: construction of the data dictionary.
-
Structuring of information : production of the
diagram of data.
-
Presentation of questions representative of
the studied field.
-
Interactive treatement of questions, on a "test"
database, using SQL language.
Practical application
To practically apply and use, on a real system, the
concepts of design and use of
databases (SQL) presented in these pages,
see the functionalities of the IBEasy+
software.
