- 2. Mongo DB isa document oriented database. It is an open source product, developed and supported by a company named 10gen. MongoDB is written in C++. The manufacturing company 10 gen has given the definition of Mongo DB: "Mongo DB is scalable, open source, high performance, document oriented database." - 10 gen MongoDB was designed to work with commodity servers. Now it is used by company of all sizes, across all industry.
- 3. What is mongoDB? Data model: using BSON (binary JSON), developers can easily map to modern object-oriented languages without a complicated ORM layer. ORM: Object Relational Mapping BSON: Binary JSON based on JSON. Lightweight, Traversable, Efficient. MongoDB is a cross-platform, document oriented database that provides, high performance, high availability, and easy scalability. MongoDB works on concept of collection and document.
- 4. Scalable High-PerformanceOpen-source, Document-Oriented database. Built for Speed Rich Document based queries for Easy readability. Full Index Support for High Performance. Replication and Failover for High Availability. Auto Sharding for Easy Scalability. Map / Reduce for Aggregation.
- 5. History of MongoDB Theinitial development of MongoDB began in 2007 when the company was building a platform as a service similar to window azure. "Window azure is a cloud computing platform and infrastructure, created by Microsoft, to build, deploy and manage applications and service through a global network."MongoDB was developed by a New York based organization named 10gen which is now known as MongoDB Inc. It was initially developed as a PAAS (Platform As A Service). Later in 2009, it is introduced in the market as an open source database server that was maintained and supported by MongoDB Inc. The first ready production of MongoDB has been considered from version 1.4 which was released in March 2010. MongoDB2.4.9 was the latest and stable version which was released on January 10, 2014. latest version is 3.6 First of all, we should know what is document oriented database?
- 6. 10gen is thecompany behind MongoDB. Founded in 2007 • Dwight Merriman, Eliot Horowitz • Doubleclick, Oracle, Marklogic, HP Worldwide Expanding Team • 140+ employees • NY, Palo Alto, London, Dublin, Sydney Set the direction & Contribute code to MongoDB Foster Community & ecosystem Provide Commercial services Provide MongoDB Management Services
- 7. Why MongoDB? SQLwas invented in the 70’s to store data. MongoDB stores documents (or) objects. Now-a-days, everyone works with objects (Python/Ruby/Java/etc.) And we need Databases to persist our objects. Then why not store objects directly ? Embedded documents and arrays reduce need for joins. No Joins and No-multi document transactions.
- 8. This may bea very genuine question that - "what was the need of mongodb although there were many databases in action?“ This is a very simple answer: All the modern applications require big data, fast features development, flexible deployment and the older database systems not enough competent, so the mongodb was obviously needed. Purpose to build MongoDB
- 9. Features of MongoDB Theseare some important features of mongoDB. 1. Support ad hoc queries In MongoDB, you can search by field, range query and it also supports regular expression searches. 2. Indexing You can index any field in a document. 3. Replication MongoDB supports Master Slave replication. A master can perform Reads and Writes and a Slave copies data from the master and can only be used for reads or back up (not writes) 4. 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.
- 10. 5. Load balancing Ithas an automatic load balancing configuration because of data placed in shards. 6. Supports map reduce and aggregation tools. 7. Uses JavaScript instead of Procedures. 8. It is a schema-less database written in C++. 9. Provides high performance. 10. Stores files of any size easily without complicating your stack. 11. Easy to administer in the case of failures. 12. It also supports: • JSON data model with dynamic schemas • Auto-sharding for horizontal scalability • Built in replication for high availability 13. Operating System : Cross-Platform Now a day many companies using MongoDB to create new types of applications, improve performance and availability.

- 12. Data as Documents MongoDBstores data in a binary representation called BSON (Binary JSON). The BSON encoding extends the popular JSON (JavaScript Object Notation) representation to include additional types such as int, long, date, floating point, and decimal128. MongoDB documents tend to have all data for a given record in a single document, whereas in a relational database information for a given record is usually spread across many tables. “Data as documents: simpler for developers, faster for users.”
- 13. How does theMongoDB data model stack up to relational databases and key-value stores? Take a look at the chart below: MongoDB scales like crazy. Whether you are sharding to scale data volume, performance or cross-data center operations, you can do it with MongoDB.

- 16. MongoDB CURD operation Fourbasic operation in mongoDB. 1. Create Operations 2. Update Operations 3. Read Operations 4. Delete Operations Create Operations: Create or insert operations add new documents to a collection. If the collection does not currently exist, insert operations will create the collection. MongoDB provides the following methods to insert documents into a collection: db.collection.insertOne( <document>, { name : “ Hyphen ” , Document status : “ pending ” } ) • db.collection.insertMany()
- 17. Update Operations: Update operationsmodify existing documents in a collection. MongoDB provides the following methods to update documents of a collection: db.users.updateMany( collection { age : { $ lt : 18 } } , update filter { $ set : { status : “ reject ” } } update action ) • db.collection.UpdateOne() • db.collection.replace() Read Operations: Read operations retrieves documents from a collection; i.e. queries a collection for documents. MongoDB provides the following methods to read documents from a collection: db.users.find( collection query criteria { age : { $ gt : 18 } } , projection { name: 1 , address : 1 } update action ) . Limit(5)
- 18. Delete Operations: Delete operationsremove documents from a collection. MongoDB provides the following methods to delete documents of a collection: db.users.deleteMany( collection { status : “ reject ”} delete filter ) • db.collection.deleteOne()
