MongoDB is a cross-platform document-oriented database that uses JSON-like documents with dynamic schemas, making it easier and faster to integrate data compared to traditional relational databases. It is developed by MongoDB Inc. and is open-source. MongoDB supports features like ad hoc queries, indexing, replication for high availability, automatic load balancing, and horizontal scalability. It is a popular choice for storing large datasets and powering modern applications.

- 2. By , Kowndinya Mannepalli MongoDB is a cross-platform document- oriented database. Classified as a NoSQL database, MongoDB eschews the traditional table-based relational database structure in favour of JSON-like documents with dynamic schemas (MongoDB calls the format BSON), making the integration of data in certain types of applications easier and faster. MongoDB is developed by MongoDB Inc. and is published as free and open-source software under a combination of the GNU Affero General Public License and the Apache License. As of July 2015, MongoDB is the fourth most popular type of database management system, and the most popular for document stores Key points of MongoDB Develop Faster Deploy Easier Scale Bigger
- 3. By , Kowndinya Mannepalli Main purpose to build MongoDB: Scalability Performance High Availability Scaling from single server deployments to large, complex multi-site architectures.
- 4. By , Kowndinya Mannepalli Main features Ad hoc queries MongoDB supports field, range queries, regular expression searches. Queries can return specific fields of documents and also include user-defined JavaScript functions. Indexing You can index any field in a document. Support ad hoc queries In MongoDB, you can search by field, range query and it also supports regular expression searches. Replication MongoDB supports Master Slave replication Duplication of data MongoDB can run over multiple servers. The data is duplicated to keep the system up and also keep its running condition in case of hardware failure. Load balancing It has an automatic load balancing configuration because of data placed in shards. • Supports map reduce and aggregation tools. • Uses JavaScript instead of Procedures. • It is a schema-less database written in C++. • Provides high performance. • Stores files of any size easily without complicating your stack. • Easy to administer in the case of failures.
- 5. By , Kowndinya Mannepalli • A NoSQL database provides a mechanism for storage and retrieval of data which is modelled in means other than the tabular relations used in relational databases. • NoSQL Database is used to refer a non-SQL or non relational database. • It is generally used to store big data and real-time web applications. Advantages • It supports query language. • It provides fast performance. • It provides horizontal scalability.
- 6. By , Kowndinya Mannepalli NoSQL database can be classified as 4 basic types: • Key value store NoSQL database • Document store NoSQL database • Column store NoSQL database • Graph base NoSQL database There are many NoSQL databases. MongoDB, Cassandra, CouchBD, Hypertable, Redis, Riak, Neo4j, HBASE, Couchbase, MemcacheDB, Voldemort, RevenDB etc. are the examples of NoSQL databases.
