Management of Relational and Non-relational Databases

Course

Databases need to be structured properly to enable efficient and effective querying and analysis of data. Build normalized, consistent, and performant relational data models. Use SQL Database Definition Language (DDL) to create the data schemas designed in Postgres and apply SQL Database Manipulation Language (DML) to migrate data from a denormalized schema to a normalized one. Understand the tradeoffs between relational databases and their non-relational counterparts, and justify which one is best for different scenarios. With a radical shift of paradigms, learn about MongoDB and Redis to get an understanding of the differences in behaviors and requirements for non-relational databases.

Find out how to keep consistency amongst your data by adding constraints.

Lesson 6

Performance with Indexes

Maximize your database performance by using indexes when and where appropriate.

Lesson 7

Intro to Non-Relational Databases

With your relational database skills in hand, you’re ready for a look into the other side of data, with non-relational databases.

Lesson 8 • Project

Udiddit, A Social News Aggregator

Investigate a poorly designed database for Udiddit, a social news aggregator. You’ll design a new, normalized and performant database and migrate over data from the previous database.
