Content Introduction· · · · · ·
In-depth learning MongoDB is divided into two parts, corresponding to the scaling MongoDB 50Tips and Tricks for Mongo DB developers Two, which is published by O ' Reilly Company. "In-depth learning MongoDB". The first part comprehensively explains the content of building and using the cluster, not only explains the use of MongoDB from the perspective of application developers, but also introduces the management of the cluster from the aspect of operation and maintenance. The content includes setting up MongoDB clusters through sharding, how shards work, querying and updating data, manipulating, monitoring, and backing up clusters, error handling. The second part introduces the application design, implementation, optimization, data security and management techniques, including the pros and cons of normalization and inverse normalization, and the failure recovery of replication groups.
