NoSQL Databases MongoDB
What is NoSQL?
NoSQL databases (aka "not only SQL") are non-tabular databases and store data differently than relational tables. NoSQL databases are available a selection of types supported their data model. The foremost types are document, key-value, wide-column, and graph. They provide flexible schemas and scale easily with large amounts of data and high user loads.
What is a NoSQL database?
When people use the term “NoSQL database,” they typically use it to ask any non-relational database. Some say the term “NoSQL” stands for “non SQL” while others say it stands for “not only SQL.” Either way, most agree that NoSQL databases are databases that store data during a format apart from relational tables.
Can MongoDB replace NoSQL?
As we had limitations with Relational Databases for storing and processing the huge volume of social media and web data. NoSQL database was a rescue for large Data. NoSQL database allowed the programme1r to execute the database with ease and efficiency. NoSQL database is of 4 types. NoSQL is capable of handling far more data in terms of both volume and complexity. NoSQL databases are either schema-free or have relaxed schemas. For execution, MongoDB provides aggregation feature to process your data efficiently. We use Map Reduce model for aggregation operations.
A MapReduce could also be a programming model composed of two procedures: Map () and Reduce ().Map () procedure performs filtering and sorting while Reduce () procedure performs a summary operation. MongoDB can run over multiple servers. The data is duplicated to remain the system up and keep its running condition in hardware failure. MongoDB could also be a schema-less database. In MongoDB architecture – there are different documents in one collection. The gathering is schema-less to possess different content, fields, and size comparing another document within an equivalent collection. The features of NoSQL align with the offering of MongoDB. So, NoSQL cannot replace MongoDB or MongoDB cannot replace NoSQL.
NoSQL databases provide a selection of benefits including flexible data models, horizontal scaling, lightning fast queries, and straightforward use for developers. NoSQL databases are available a selection of types including document databases, key-values databases, wide-column stores, and graph databases.
MongoDB is that the world's hottest NoSQL database.
