MongoDB is a document-oriented cross-platform database program. It’s classified as a NoSQL program. It utilizes JSON-like documents with schema, is developed by MongoDB, and licensed under the Server Side Public License.
- Each database comprises of collections complete with documents. Each document varies with a different number of fields. The content and size of each document can vary from one another.
- The rows often referred to as documents in MongoDB don’t need to have a schema structure defined beforehand. Rather, the fields can be developed on the fly.
- The document design is aligned with how developers develop their objects and classes in their different programming languages. Developers often say that their classes aren’t columns or rows but come with a clear structure complete with key-value pairs.
- The data representation available with MongoDB enables users to illustrate hierarchical relationships to reserve arrays and more intricate structures with ease.
- MongoDB environments are scalable
Why Use MongoDB?
There are various reasons why you should consider using MongoDB as seen below.
Its Document Oriented
Seeing that MongoDB is a NoSQL type of database, rather than having data in a comparative type format it reserves the data in documents. This makes MongoDB flexible and versatile to real business world requirements and circumstances.
Ad Hoc Queries
MongoDB supports inquiring by range queries, field, and regular expression searches. Queries can be made to display certain fields with documents.
Indexes can be developed to enhance the performance of searches within MongoDB. Any field within a MongoDB document can easily be indexed.
MongoDB can offer high availability with duplicate sets. A duplicate set comprises of two or more MongoDB occurrences. Every duplicate set member can play the role of secondary or primary duplicate at any time.
The primary duplicate is the major server that collaborates with the client and executed all the write/read operations. Secondary duplicates preserve a replica of the data of the primary with inbuilt duplication. In the even a primary duplication fails, the duplication set switches to the secondary automatically before becoming the primary server.
MongoDB utilizes the approach of sharding to scale horizontally through splitting data across different MongoDB instances. MongoDB can traverse over different servers, duplicating data or balancing data to ensure the system continues running in the event of hardware failure.
