Analyst-Programmer, I teach computer science and programming at all levels.
My teaching method is: simple, effective and very quickly learned by the students.
I take all the time necessary for the student to really understand the course. My goal is to simplify the material as much as possible during the explanation and I always use examples to facilitate understanding.
I never skip topics that I don't understand because during the time the student is learning, I too am learning something new!

Je propose une formation en SQL (requête principalement, moins la construction d'un modèle de donnée).
La formation que je propose s'adresse à tout les niveaus (introduction aux selections, insertions, jointures, ...) ainsi qu'à des utilisateurs plus avancés (fonctions analytiques, ...).
Je propose aussi une formation a tout les langage C , C sharp , java , php
Je suis ouvert également pour des scéances de questions/réponses.

Diplômé ingénieur en informatique depuis 2008 , je travaille à présent en tant qu'analyste fonctionnel sur Bruxelles.
Durant mes études, je me suis principalement intéressé aux développements en C , C++ , JAVA , C sharp ainsi qu'à l'analyse Uml , Merise
Dans mon travail au quotidien, je suis à présent en relation avec des clients et définit les analyses pour une équipe de développement en C sharp.

Much of the world's raw data—from electronic medical records to customer transaction histories—lives in organized collections of tables called relational databases. Being able to wrangle and extract data from these databases using SQL is an essential skill within the data industry and in increasing demand.

In this two-hour introduction to SQL, you'll get to know the theory and the practice through bite-sized videos and interactive exercises where you can put your new-found skills to the test. SQL is an essential language for building and maintaining relational databases, which opens the door to a range of careers in the data industry and beyond. You’ll start this course by covering data organization, tables, and best practices for database construction.

The second half of this course looks at creating SQL queries for selecting data that you need from your database. You’ll have the chance to practice your querying skills before moving on to customizing and saving your results. PostgreSQL and SQL Server are two of the most popular SQL flavors. You’ll finish off this course by looking at the differences, benefits, and applications of each. By the end of the course you’ll have some hands-on experience in learning SQL and the grounding to start applying it on projects or continue your learning in a more specialized direction.

Relational Databases
Before writing any SQL queries, it’s important to understand the underlying data. In this chapter, we’ll discover the role of SQL in creating and querying relational databases. Using a database for a local library, we will explore database and table organization, data types and storage, and best practices for database construction.

Querying
Learn your first SQL keywords for selecting relevant data from database tables! After practicing querying skills in a database of books, you’ll customize query results using aliasing and save them as views so they can be shared. Finally, you’ll explore the differences between SQL flavors and databases such as PostgreSQL and SQL Server.

Le cours SQL (Structured Query Language) est conçu pour enseigner les concepts fondamentaux et avancés de la gestion de bases de données relationnelles afin de maîtriser la création et la gestion de bases de données et d'apprendre à interroger et à manipuler des données à l'aide de SQL.
Nous avons plusieurs chapitres abordés dans ce cours tels que : introduction aux bases de données, SQL de base, manipulation de données, fonctions SQL, jointures, gestion de base de données, SQL avancé et meilleures pratiques.
De plus, les cours sont modifiables en fonction des besoins des participants, l'essentiel étant qu'à la fin, ils soient capables de concevoir, d'interroger et de gérer efficacement des bases de données relationnelles, en utilisant SQL comme principal outil de manipulation de données.
Par ailleurs, ce cours s'adresse aux débutants souhaitant acquérir des compétences en SQL ainsi qu'aux professionnels souhaitant renforcer leurs connaissances.
