For the past 40 years, the relational database has been the dominant model for persisting data. While SQL databases are not going away anytime soon, the NoSQL ("not only SQL") movement challenges the relational database as the default persistence layer for modern applications.

Learn how you can leverage both relational and NoSQL databases, as well as managed services, to improve your apps and provide compelling systems of engagement. For example, use ElasticSearch to provide full text search, PostGIS in PostgreSQL for geospatial capabilities, Redis for improved performance, or a document database such as CouchDB or MongoDB for a flexible schema.

Applying principles from Domain-Driven Design such as strategic design and bounded contexts, this presentation will help you choose and apply the right data layer for your application's model or models. We will explore relational databases, graph databases, document databases, full text search, caching with key/value stores, polyglot persistence, horizontal scaling, eventual consistency, CQRS, event sourcing, and data layers for microservices.

After attending this webcast, you will be able to answer these questions:

  • What open source NoSQL databases are available to developers today?
  • What type of database or databases should I choose for my application?
  • What is Domain-Driven Design and how can I use it to think about the data layer for my application?
