Polyglot Persistence for Java Developers - Moving Out of the Relational Comfort Zone

Relational databases have long been considered the one true way to persist enterprise data. But today, NoSQL databases are emerging as a viable alternative for many applications. They can simplify the persistence of complex data models and offer significantly better scalability, and performance. But using NoSQL databases is very different than the ACID/SQL/JDBC/JPA world that we have become accustomed to. They have different and unfamiliar APIs and a very different and usually limited transaction model. In this presentation, we describe some popular NoSQL databases – Redis, and MongoDB. You will learn about each database’s data model and Java API. We describe the benefits and drawbacks with using NoSQL databases. Finally, you will learn how the Spring Data project simplifies the development of Java applications that use NoSQL databases.

Case Study: Extending extensible web services using Spring and other goodies

Let’s imagine that you were asked to extend a web service without modifying the original implementation. How would you do that? And, what does it mean for a Web service to be extensible anyway? We answer these and other questions in this presentation where we describe a novel, proxy server-based approach for extending REST and SOAP APIs without having to modify the initial implementation. You will learn about the REST maturity model and what it means for a web service to be extensible. We describe how we built the proxy server using technologies such as the Spring framework, the Roo shell and Spring Data for Redis.
