How to use SQL functions

SQL is a programming language for managing databases. In other words, various SQL commands help you perform actions on the data you store in relational database management systems. In this SQL course, I will explain the meaning of a database, a potential candidate to store data (Oracle), and the format of a relational system. By format, I mean the way information is stored. In most cases, the table structure is followed by putting data into rows and columns. 

Additionally, this SQL course is a great option for beginners since I will explain the SQL basics and common uses. Therefore, it is not necessary for you to have any prior knowledge of SQL or relational databases. All of these concepts are going to be explained in this course on SQL fundamentals and database management!

What is SQL?

Structured Query Language (or SQL for short) is the standard language for manipulating databases in various database management systems. In this SQL course, we will use SQL for controlling data in a database. However, you can use SQL in other fields, such as data science, web development, etc. 

An important term in this topic is a query, which can be regarded as one of the SQL fundamentals. By definition, a query refers to an instruction that requires the database management system to perform a specific function. For instance, you can send a query for deleting or adding a record. 

What is a relational database? 

A relational database is a collection of data that is divided into several parts. As I have mentioned, a relational database contains data in tables. Hence, many people use relational database management systems to maintain datasets. 

Each row in a table is a record with a unique ID referred to as the key. The columns of the table contain attributes of the data. It is common that every record has values for every attribute. This makes it easy to establish relationships between different data. 

What will you find in this SQL online course? 

In this SQL course, I will begin by explaining the main concepts related to databases. For instance, I will discuss the meaning of a database, Oracle, table, relational database, entity-relationship logic in databases, etc. Additionally, this SQL online course will review SQL: the programming language for controlling the content stored in databases. 

Furthermore, I will provide you the steps for installing a VirtualBox since the installation of Oracle might cause some issues for users. After learning the SQL basics, you will be introduced to a topic that might be more interesting: SQL statements, table descriptions, the SELECT statement, aliasing the columns, the DISTINCT keyword, and other important principles. 

After the explanations on SQL fundamentals, I will start discussing the WHERE clause, comparison, and logical operators. This SQL course will examine many more functions, operators, and actions that you can use on your database. Therefore, start learning with me in this SQL online tutorial to have access to the principles of SQL and database management anytime.
