NoSQL is synonymous with Object Oriented Database?

There is a confusion of concepts here in your question. But responding in essence, no, they are not synonyms .

NoSQL refers to databases that use non-relational database technologies, not necessarily object-oriented . NoSQL, by the way, means Not Only SQL . This means that the database in question may (or may not) answer SQL statements. Typically databases respond to sentences in their own format or in other known formats (such as json , for example).

The Wikipedia article in English separates these databases into several taxonomies, the most important being the format as each database stores information:

• As Column
  • Accumulator, Cassandra, HBase
• As Document
  • Clusterpoint, Couchbase, MarkLogic, MongoDB
• As a key-value
  • Dynamo, FoundationDB, MemcacheDB, Redis, Riak, FairCom c-treeACE
• As a Graph
  • Allegro, Neo4J, OrientDB, Virtuoso

An object-oriented database typically holds an object of a known language , such as Zope Object Database that saves objects python , without necessarily having a transliteration of data.

Subtly different, a document-oriented database (which is often confused with an object-oriented database) stores documents in some specific format . For example, MongoDB stores documents in the form bson ("Binary JSON ", or" JSON Binary "), which is a variation of the json . For this case, for a document to become an object, it would have to have a translation (or transliteration of data) of the document into the language object in question.

In addition, there are databases that store key-values, that is, a large associative array where each index stores a complex data structure, and the banks that store columns, which are as documents, but with each column having a value of timestamp itself.
