Database Development & Administration with SQL

What is a database? A database is a collection of data stored in a format that makes it secure and easy to retrieve and manage. It is the security and management efficiency that makes database products attractive. There are two kinds of database systems: Relational and NoSQL.
Relational Database Management System(RDBMS) stores data in a database component called Table in ROWS and COLUMNS. One or more tables are usually related together, hence the name relational. Example includes MySQL, SQL Server, Oracle, etc.

NoSQL database systems on the other hand store data in documents not tables, and do not use the SQL language for data administration. Examples include MongoDB, Cassandra, Redis etc.

This course is all about RDBMS and SQL. And we will be using the MySQL RDBMS product. Please note that the SQL language is 95% the same on all RDBMS products, with minor syntactical differences. Meaning that the SQL we will learn with MySQL in this course will be applicable to other RDBMS products like SQL Server, Oracle, PostgreSQL, etc.
