SQL Databases SQL Databases NoSQL Databases Language SQL databases use structured query languages to perform operations, requiring the use of predefined schema to better interact with the data. On the other hand, NoSQL databases use a dynamic schema to query data. Also, some NoSQL databases ...
Each row has a key, so you can also think of this model as a 2d evolution of a key value store. Query languages for wide-column data models are database specific. A popular example is CQL (Cassandra Query Language), which looks similar to SQL, but is a very limited subset. Text Sea...
NoSQL stands for “Not only SQL”. It refers to any “non-relational database”. This implies that a NoSQL database may keep and access data without utilizing SQL or you may mix the flexibility of JSON with the capability of SQL. NoSQL databases are therefore designed to be...
The column families reside in a keyspace. Each keyspace holds an entire NoSQL data store and has a similar role or importance that a schema has for a relational database. But NoSQL data stores have no set structure, so keyspaces represent a schemaless database containing the design of...
