Why is MongoDB the best database?
Scalable and Reliable MongoDB is highly scalable, using shards. Horizontal scalability is a big plus in most NoSQL databases. MongoDB is no exception. It is also highly reliable due to its replica sets, and the data is replicated in more nodes asynchronously.
Is Cassandra a document store?
Columnar Databases: HBase and Cassandra is a type of Columnar database. Document Databases: CouchDB and MongoDB is a type of Document Database. Document databases store and retrieve semi-structured data in the format of documents such as XML, JSON, etc. Graph Databases: Polyglot, Neo4J is a type of Graph Database.
What distinguishes MongoDB as the best among databases?
A key benefit of the MongoDB design is that the database is extremely easy to scale. Configuring a sharded cluster allows a portion of the database, called a shard, to also be configured as a replica set. In a sharded cluster, data is distributed across many servers.
Is MongoDB a good choice?
NoSQL databases like MongoDB are a good choice when your data is document-centric and doesn’t fit well into the schema of a relational database, when you need to accommodate massive scale, when you are rapidly prototyping, and a few other use cases.
What is the difference between HBase and MongoDB?
HBase is used to store structured data. MongoDB is used to store any kind of data. It has distributed database. It has decentralized database. HBase is less complex than MongoDB. It is more complex than HBase. Attention reader! Don’t stop learning now.
What is HBase in Hadoop?
1. HBase : This model is used to provide random access to large amount of structured data. It build on the top of the hadoop file system and column-oriented in nature. It used to store the data in HDFS. It is open source database that provide the data replication.
What is MongoDB and how does it work?
MongoDB is a schema-less database and stores data as JSON-like documents (binary JSON). This provides flexibility and agility in the type of records that can be stored, and even the fields can vary from one document to the other.
What are the strengths of HBase?
One of the strengths of HBase is its use of HDFS as the distributed file system. This allows the database to store large data sets, even billions of rows, and provide analysis in a short period.
