NoSQL-Database is something quite new. I heard the first time about it a couple months ago and even read an interesting article about the topic which was in truth too complicated for me.
But recently I run into the question who a web shop like Amazon is storing its data. Surprisingly this is no secret and Amazon has published a description about their technology and you can even download an API to connect to the database and you can create your own DynamoDB on the Amazon cloud.
Here is a short summary about the concept in German. I had no time to translate it into English so far. Hope it is correct from a technical point of view!
I have a new hobby. In March I had an accident while jogging in the wood and had to go to hospital for a medical treatment. Since then I had to reduce my sportive activities which was not easy a the beginning.
Meanwhiles it is better and I am even happy because I spend more time with my kids again. But I also have a new hobby. Together with a friend we have rented a small room in the next building and do painting there.
This is a funny hobby. I was quite a good painter in school and even won once a school championship. But since then I lever practiced it. But my friend has this hobby since more than ten years, so once a month we meet in our room and drink beer and paint.
This is one of the good paintings I have done so far. Its not easy!
