Index Keyspace (distributed data store)

A keyspace (or key space) in a NoSQL data store is an object that holds together all column families of a design. [1]

Column family

A column family is a database object that contains columns of related data.

Data store

A data store is a repository for persistently storing and managing collections of data which include not just repositories like databases, but also simpler store types such as simple files, emails etc.

Database schema

The database schema of a database system is its structure described in a formal language supported by the database management system (DBMS).

Distributed data store

A distributed data store is a computer network where information is stored on more than one node, often in a replicated fashion.

Entity–relationship model

An entity–relationship model (ER model for short) describes interrelated things of interest in a specific domain of knowledge.

NoSQL

A NoSQL (originally referring to "non SQL" or "non relational") database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases.

Relational database management system

A relational database management system (RDBMS) is a database management system (DBMS) based on the relational model invented by Edgar F. Codd at IBM's San Jose Research Laboratory.

Relational model

The relational model (RM) for database management is an approach to managing data using a structure and language consistent with first-order predicate logic, first described in 1969 by Edgar F. Codd, where all data is represented in terms of tuples, grouped into relations.

Row (database)

In the context of a relational database, a row—also called a tuple—represents a single, implicitly structured data item in a table.

Super column

A super column is a tuple (a pair) with a binary super column name and a value that maps it to many columns.

Twitter

Twitter is an online news and social networking service on which users post and interact with messages known as "tweets".

UTF-8

UTF-8 is a variable width character encoding capable of encoding all 1,112,064 valid code points in Unicode using one to four 8-bit bytes.
