That progressed into Sybase and Microsoft SQL Server. I have cut my teeth on relational databases however; the one size fits all no longer applies anymore. Those previous … More Neo4j Database – Part 01 – Foundation
In the previous blog I discussed transactions. In this blog I want to highlight the scalability and high availability features available in Redis. RDBMS’s are designed to run on big boxes. Scaling is done virtually by throwing more hardware at the server. This is in complete contract to NoSQL databases which are designed to be … More Redis Database – Part 08 – Scalability and High Availability
In the previous blog I highlighted the scalability and high availability features available in Redis. In this blog I will show how a demo application uses Redis to cache searches sent to Twitter. The code can be found on Github here. Demo Application In this last post I thought I would show one of the … More Redis Database – Part 09 – Twitter Redis Caching
In the last blog I discussed how we can apply filters to our data. In this blog I will discuss how we deal with transactions. Transactions If you come from a relational database background you will be very familiar with transactions.
