Should I use NoSQL or SQL?

If your data is very structured and ACID compliance is a must, SQL is a great choice. On the other hand, if your data requirements aren’t clear or if your data is unstructured, NoSQL may be your best bet. The data you store in a NoSQL database does not need a predefined schema like you do for a SQL database.

Is Cassandra a NoSQL?

Apache Cassandra™ is a distributed NoSQL database that delivers continuous availability, high performance, and linear scalability that successful applications require.

Does NoSQL use SQL?

NoSQL databases are scaled by increasing the databases servers in the pool of resources to reduce the load. SQL databases uses SQL ( structured query language ) for defining and manipulating the data, which is very powerful. In NoSQL database, queries are focused on collection of documents.

What is NoSQL and its types?

There are four big NoSQL types: key-value store, document store, column-oriented database, and graph database. Each type solves a problem that can’t be solved with relational databases. Actual implementations are often combinations of these. OrientDB, for example, is a multi-model database, combining NoSQL types.

Will NoSQL replace SQL?

Despite its rising popularity, NoSQL is not a replacement for SQL. It’s an alternative. Some projects are better suited to using an SQL database, while others work well with NoSQL. Some could use both interchangeably.
