Say No2SQL or NoSQL – MongoDB
One year ago ( or even more ) I found which was called MongoDB. This database concept is designed around “NoSQL”. The first time I saw it i thought: Uh, why the hell should I use it? And even the syntax it is used to get access to the stored data locked weird to me. You access your data like an array ( In general ). And I thought: It must be slow, if you compare MySQL, for example, against MongoDB. The idea was, as every language when you remove int, string and so on, the engine must first find out, which type of data is stored. But after reading a few benchmarks and tutorials about it. I can´t admit, that this database “type”. Is pretty powerful, easy to use and amazingly fast.
But you might still think: Why should I use, learn or even keep an eye on it?
Well, most users forgot, or at least: don’t want to know what happened to the MySQL developers. ( They were bought by SUNSun reviews
/ OracleOracle reviews ) They promised to keep MySQL alive as it is. And want to keep it opensource. But we all know that this is just a promise… The EU still keep an on SUN/ Orcale and MySQL. Cause they fear the same thing as many users fear. I dont think they could “close” MySQL now or later. But they could do other things. Reduce resources, introduce buggy versions. Stopping to work with the community and much more.
But now I don´t fear the death of MySQL, MongoDB is getting better and better. And if MySQL lose users, MongoDB will get more users
