NoSQL. NoSQL (originally referring to "non- SQL " or "non-relational") [1] is an approach to database design that focuses on providing a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases. Instead of the typical tabular structure of a relational database, NoSQL ...
When choosing availability over consistency, the system will always process the query and try to return the most recent available version of the information, even if it cannot guarantee it is up to date due to network partitioning. In the absence of a partition, both availability and consistency can be satisfied. [9]
cassandra.apache.org. Apache Cassandra is a free and open-source, distributed, wide-column store, NoSQL, database management system designed to handle large amounts of data across multiple commodity servers, providing availability with no single point of failure. Cassandra supports clusters and spanning of multiple data centers [ 2 ] with ...
A document-oriented database is a specialized key-value store, which itself is another NoSQL database category. In a simple key-value store, the document content is opaque. A document-oriented database provides APIs or a query/update language that exposes the ability to query or update based on the internal structure in the document. This ...
Amazon DynamoDB is a fully managed proprietary NoSQL database offered by Amazon.com as part of the Amazon Web Services portfolio. [ 2 ] [ 3 ] DynamoDB offers a fast persistent key–value datastore with built-in support for replication , autoscaling , encryption at rest, and on-demand backup among other features.
Keyspace (distributed data store) A keyspace example with a number of column families. A keyspace (or key space) in a NoSQL data store is an object that holds together all column families of a design. [1][2] It is the outermost grouping of the data in the data store. [3] It resembles the schema concept in Relational database management systems. [4]
ObjectStore is a commercial object database, a specialized type of NoSQL database designed to handle data created by applications that use object-oriented programming techniques, avoiding the object–relational mapping overhead required when using object-oriented data with a relational database. It is inspired by the Statice database ...
