Common API Usage for Java operations mongoDB2.6

For MongoDB, there is not much difference between learning style and learning relational database

Start by learning how to insert, find, Update, remove, and then page, sort, index, and then the master-slave copy, copy set, Shard, and so on

The last is to practice the so-called advanced usage through the various drivers it provides (such as Java, PHP, node. js, and so on)

In addition: There are plsql developer,mysql with respect to Oracle Heidisql

MongoDB is no exception, it has a graphical tool called Mongovue, I use the 1.5.3 cracked version (not every 15 days will have to change the type of registry)

The following illustration shows Java as an example of the common operation of MongoDB API usage
