Nonrelational databases enforce less strict rules on database design and using them can be beneficial for many use cases. In this video, learn the basics of nonrelational databases.
- [Narrator] Around 2012, a new class of databases came out…with so called Document Databases such as MongoDB,…Couchbase, Redis, that's the key value store,…CouchDB, DynamoDB, that's a key value stores as well,…and Cassandra, and we have a whole set of Relational…Databases which is still centered around Oracle SQL server,…MySQL, SQLite is quite new, and PostgreSQL.…These new document databases had a few large differences…to relational databases.…
Let's look at them.…They are synonymic called NoSQL Databases very often.…So actually they have existed since the 1960s but they…got very popular with so-called Web 2.0.…As most SQL databases are non-relational, they usually also…have no integrity enforcement.…They are also not, by definition, ACID compliant.…And they are often a synonym for document databases, but…there are others like, for instance,…graph databases as well.…
There's schema-less.…This means they have no predefined data structure and they…can basically store arbitrary data.…This also means actually that the schema management moves…
