Qu’est-ce qu’Oracle SQL ?
SQL signifie Structured Query Language : le langage que les développeurs utilisent pour interagir avec les bases de données afin de créer, lire, mettre à jour et supprimer des enregistrements de base de données et gérer d’autres aspects de ces bases de données. L’ANSI a créé la norme pour SQL. De nombreux fournisseurs de bases de données, comme Oracle, développent cette norme pour créer leur propre version du langage. Oracle SQL est conforme aux normes ANSI SQL, avec des fonctionnalités conçues spécifiquement pour le système de gestion de base de données Oracle. Ce SGBDR a été lancé en 1977 en tant que premier système de gestion de bases de données relationnelles disponible dans le commerce et détient la première part de marché mondiale pour les systèmes de gestion de bases de données relationnelles. Oracle SQL étend la norme SQL avec un langage procédural PL/SQL et ajoute la possibilité d’utiliser le langage de programmation Java.
Quels métiers utilisent Oracle SQL ?
Avoir des compétences Oracle SQL peut ajouter de la valeur à de nombreuses carrières. Le plus évident est d’être administrateur de base de données dans des entreprises qui utilisent le système de gestion de base de données Oracle. Mais les dialectes SQL sont assez similaires et la connaissance d’Oracle SQL peut s’appliquer à de nombreux types de bases de données relationnelles et ne vous limite pas à Oracle. Les développeurs de bases de données utilisent également Oracle SQL toute la journée pour créer de nouvelles bases de données et structures de tables. La plupart des applications nécessitent une base de données pour fonctionner, de sorte que les ingénieurs logiciels et les développeurs Web utilisent fréquemment Oracle SQL. Les scientifiques des données doivent accéder aux données pour créer des modèles d’apprentissage automatique et trouver des tendances, et une grande partie de ces données seront stockées dans des bases de données qui nécessitent une connaissance de SQL pour être récupérées et transformées. Les analystes commerciaux utilisent également Oracle SQL pour générer des rapports qui aident les entreprises à passer à l’étape suivante.
Quelles compétences dois-je avoir avant d’apprendre Oracle SQL ?
Il n’y a aucun prérequis pour apprendre Oracle SQL. Oracle SQL a une syntaxe plus simple que de nombreux langages de programmation standard et se lit presque comme l’anglais. La plupart des gens peuvent comprendre ce qu’une requête SQL essaie de faire avant même de connaître le langage. Tout ce dont vous avez besoin est un intérêt pour la langue et un engagement à apprendre. Cela dit, certaines choses pourraient vous aider dans votre formation Oracle SQL si vous les connaissez déjà. Si vous connaissez les feuilles de calcul Excel et comprenez le fonctionnement des colonnes et des lignes, vous pouvez appliquer ces connaissances aux tables de base de données Oracle. Il est également utile de connaître au moins les concepts de fonctionnement d’un système de gestion de base de données relationnelle. De plus, si vous connaissez déjà un langage de programmation, cela vous aidera à apprendre les fonctionnalités étendues d’Oracle telles que PL/SQL.
Nouveau contenu
Vous trouverez des DBA dans presque toutes les organisations/entreprises, pour maintenir la base de données de l’organisation. Devenir DBA dépend totalement de la connaissance que vous avez de l’architecture globale d’Oracle Database. Ce n’est un secret pour personne que la technologie progresse à un rythme rapide. De nouveaux outils sont publiés chaque jour, Oracle met à jour son système et il est crucial de rester au courant des dernières connaissances. Avec ce cours, vous aurez toujours la possibilité de suivre les dernières tendances.

Getting Started to Oracle DBA

What is oracle SQL?
SQL stands for Structured Query Language—the language developers use to interact with databases to create, read, update, and delete database records and manage other aspects of those databases. ANSI created the standard for SQL. Many database vendors, like Oracle, expand on this standard to create their version of the language. Oracle SQL is compliant with ANSI SQL standards, with features designed specifically for the Oracle database management system. This RDBMS was released as the first commercially available relational database management system in 1977 and holds the top market share worldwide for relational database management systems. Oracle SQL extends the SQL standard with a procedural language PL/SQL and adds the ability to use the Java programming language.

Oracle Database Setting Up
oracle dba:
Oracle Database is an enterprise database that can handle online transaction processing needs, as well as data warehousing and workloads for enterprise resource planning (ERP). Oracle DB was designed to be a flexible way to handle large applications and massive amounts of structured data.

What careers use Oracle SQL?
Having Oracle SQL skills can add value to many careers. The most obvious is being a database administrator in enterprises that use the Oracle database management system. But SQL dialects are pretty similar, and knowledge of Oracle SQL can apply to many types of relational databases and doesn't limit you to Oracle. Database developers also use Oracle SQL all day long to create new databases and table structures. Most applications require a database to function, so software engineers and web developers also use Oracle SQL frequently. Data scientists must access data to create machine learning models and find trends, and a lot of this data will get stored in databases that require a knowledge of SQL to retrieve and transform. Business analysts also use Oracle SQL to generate reports that help businesses get to their next stage.

What skills should I have before learning Oracle SQL?
There are no prerequisites to learning Oracle SQL. Oracle SQL has a simpler syntax than many standard programming languages and reads almost like English. Most people can understand what a SQL query is trying to do before they even know the language. All you need is an interest in the language and a commitment to learning. That said, some things could help with your Oracle SQL education if you are already familiar with them. If you are familiar with Excel spreadsheets and understand how columns and rows work, you can apply that knowledge to Oracle database tables. It also helps to know at least the concepts of how a relational database management system works. Also, if you already know a programming language, that will help learn Oracle's extended features like PL/SQL.

It was a great experience learning SQL from someone who has worked on the technology for 12 years. The entire course is well structured so that even a beginner can understand the concepts. It has all the necessary information about different parts of SQL from statements and their variations to the most common functions that are used in Oracle SQL scripts. After taking this course I feel confident that I can pass the Oracle Certification Test.

Oracle Database Administration Tips & Tricks
oracle rac: There are many issues to be controlled by dba during the day for a proactive administration. Here are some of them which should be a routine of dba in the early morning every day.
oracle database administration: If you do not want to live any surprises that will cause downtime by the day, it is better to have a look at these once a month at least.
oracle dba: Queries are the assistants of dba. Every dba has his/her own query scripts that are used for database checks and he/she wants to share them with nobody. I will make an exception for you.
oracle database administration: AWR and ASH are the most used reports whenever a problem occurs on the database. Opatch gives you the patch level of the database. As a dba, you should know how to get them.
oracle database: These are some errors you may come across during the course. I show solutions or workarounds for those errors.
