What is NoSQL PDF?

NoSQL Database is a non-relational Data Management System, that does not require a fixed schema. It avoids joins, and is easy to scale. The major purpose of using a NoSQL database is for distributed data stores with humongous data storage needs. NoSQL is used for Big data and real-time web apps.

How do I choose a NoSQL database?

Choose NoSQL if you have or need:

  1. Semi-structured or Unstructured data / flexible schema.
  2. Limited pre-defined access paths and query patterns.
  3. No complex queries, stored procedures, or views.
  4. High velocity transactions.
  5. Large volume of data (in Terabyte range) requiring quick and cheap scalability.

How NoSQL is used in big data analytics?

NoSQL allows for high-performance, agile processing of information at massive scale. It stores unstructured data across multiple processing nodes, as well as across multiple servers. As such, the NoSQL distributed database infrastructure has been the solution of choice for some of the largest data warehouses.
