How is MongoDB better than other SQL databases?

Question

Now and days, there are so many android applications in the market.
Can someone has experience on those applications in the context of databases ?

Answer 1

MongoDB allows a highly flexible and scalable document structure. For e.g. one data document in MongoDB can have five columns and the other one in the same collection can have ten columns. Also, MongoDB database are faster as compared to SQL databases due to efficient indexing and storage techniques.

Answer 2

MongoDB is not exactly "better" than other DBs in any sense. It totally depends on your requirement.

MongoDB offers a JSON based document storage, which can be highly unstructured. i.e every document in a collection ( akin to row in a table) can have its own structure. So for highly unstructured data it is great, but managing such data also has problems.
