Introduction to Database Queries

Por: edX . en: , ,


This course is an introduction to the basic concepts, organization, and implementation models of databases, with an emphasis on the relational model. Among the topics covered are the development of simple queries that retrieve and mutate the data in a database. Data Manipulation Language (DML) is a subset of SQL that is used by database developers to create, maintain, and query facts in the database. Students gain a thorough understanding of the DML syntax and the options available when retrieving facts back from the database. Database development and administration skills are required in most Information Technology, Software Engineering, Cybersecurity, and Computer Science jobs. The course utilizes the open-source relational database MySQL. MySQL and it's open-source fork MariaDB are used in millions of web apps to persist the application data and provide query processing. The applied SQL labs expand on the classroom lectures to provide students with hands-on experience with a relational database management system (RDBMS) and structured query language (SQL).
