Once a database is part of your IT infrastructure, you need to protect and maintain it. You also have to ensure that it is operating at optimal capacity. This course focuses on the database administrator (DBA), the individual charged with building, maintaining, and backing up the database. Explore key responsibilities and tasks performed by the DBA involving the security, migration, troubleshooting, and configuration of databases. Discover how the role of the DBA compares to that of a database developer. Finally, learn about common maintenance functions performed for a database such as backup and restore, user management, and performance tuning. Upon completion of this course, you'll understand the role of a DBA and how the DBA's day-to-day responsibilities differ from those of a database developer.

Most businesses are unable to function without a database, even if it's just a filing cabinet. With more and more data coming from multiple sources comes an increased demand for secure and well-performing databases with adequate storage. Take this course to get a firm understanding of what exactly data means and why a database management system (DBMS) is so important for data management. Examine the origins of data and how it's stored and manipulated. Discover the different DBMS types. And learn about the roles and responsibilities involved in using a DBMS. Furthermore, find out how a DBMS can contribute to providing sound and reliable data. Navigate the MySQL Workbench to see the capabilities of an RDBMS (relational database management system) firsthand. After taking this course, you'll be able to recognize the features and capabilities of a reliable DBMS.

Because a database is only the storage medium, we need to use a different kind of tool in order to work with that stored data. Take this course to learn how to use structured query language (SQL) to manage data in a relational database management system (RDBMS). Perform create, read, update, and delete (CRUD) operations on data using SQL, to make raw data useful. Examine data definition language (DDL) commands that work with database and table objects. Use SQL to add constraints to data in tables, for example, to specify what kind of data gets stored in which column. And explore the repercussions of constraint violation. After completing this course, you will be able to illustrate how SQL can be used within a database to add and secure tables.

Stored data can be used to derive all kinds of information. And the proper storage and use of data can contribute to better business decisions. Use this course to learn how to use a relational database management system (RDBMS) to retrieve vital information. Explore the purpose of an RDBS. Examine various databases in the marketplace, taking an in-depth look at the history and features of the most popular ones, like Oracle and SQL Server. Work with MySQL Workbench, observing how records relate to tables and how tables are connected. Discover primary database terminology. Learn about organizing data and using normalization to make data retrieval easier. And find out about E.F. Codd's contribution to database evolution. Upon completion, you'll know how to glean new information from data stored in an RDBMS.

The data stored in a database can be used in a variety of ways. Take this course to explore the power of the database as a tool for storing, manipulating, and retrieving data. Use data definition language (DDL) commands to clarify structures like schema, database, and tables. Learn the most important data manipulation language (DML) commands and execute a data query language (DQL) statement. Finally, explore how tables can be combined via joins and subqueries, producing new information from existing data. Upon completion, you will be comfortable using basic commands to set up and work with databases.
