Slides online: “NoSQL takes over! Alternatives for Integration of NoSQL databases” – NoSQL Roadshow Zurich

Posted in Persistence on September 19th, 2013 by Kai Wähner

Slides from my talk at NoSQL Roadshow 2013 in Zurich are online. NoSQL Roadshow is a great event series by Trifork, which offers a lot of NoSQL sessions and events all over the world.

Presentation: “NoSQL takes over! Alternatives for Integration of NoSQL databases”

SQL cannot solve several problems emerging with big data. NoSQL comes to the rescue, but therefore it does not use SQL as its query language or give full ACID guarantees. Thus, in the future you will have to integrate these NoSQL databases as you integrate SQL databases today.

Book Review: “Getting Started with NoSQL” by Gaurav Vaish (Packt Publishing)

Posted in Persistence on April 24th, 2013 by Kai Wähner

Getting Started with NoSQL” is a new book by PACKT PUBLISHING. It gives an introduction to different NoSQL concepts and products. Besides, it explains the differences to SQL databases and when to use which one.

First, the book defines NoSQL and explains what it is and what it is not. Especially, the characteristics and differences compared to SQL are described. The next chapter explains most important NoSQL storage types: Column-oriented databases, document stores, key-value stores, and graph databases. Advantages and disadvantages of these concepts are explained in detail, before comparing most important NoSQL products such as Cassandra, Neo4j, MongoDB or Redis. A case study (which uses MongoDB) concludes the book to show how an implementation with a NoSQL database is different from using a relational database.

Systems Integration in the NoSQL Era with Apache Camel and Talend (MongoDB, Neo4j, HBase, AWS S3, Hazelcast, CouchDB)

Posted in EAI, IT Conferences, Persistence on February 28th, 2013 by Kai Wähner

In February 2013, I was at ApacheCon NA 2013 in Portland, Oregon, USA. It was a small, but great conference. I met so many awesome Apache experts and learned a lot about several Apache projects.

Besides all of the Hadoop related projects, I was especially interested in Apache Syncope, an open source system for managing digital identities in enterprise environments, and Apache Streams, a new Incubator project that aims to develop a scalable server for the publication, aggregation, filtering and re-exposure of enterprise social activities.
