    en.wikipedia.org/wiki/MonetDB

    MonetDB is an open-source column-oriented relational database management system (RDBMS) originally developed at the Centrum Wiskunde & Informatica (CWI) in the Netherlands.It is designed to provide high performance on complex queries against large databases, such as combining tables with hundreds of columns and millions of rows.

    en.wikipedia.org/wiki/Database_model

    A database model is a type of data model that determines the logical structure of a database. It fundamentally determines in which manner data can be stored, organized and manipulated. The most popular example of a database model is the relational model, which uses a table-based format.

    en.wikipedia.org/wiki/Cardinality_(data_modeling)

    In the object-oriented application programming paradigm, which is related to database structure design, UML class diagrams may be used for object modeling. In that case, object relationships are modeled using UML associations, and multiplicity is used on those associations to denote cardinality. Here are some examples: [5]

  9. SciDB - Wikipedia

    en.wikipedia.org/wiki/SciDB

    Stonebraker claims that arrays are 100 times faster in SciDB than in a relational DBMS on a class of problems. [2] It is swapping rows and columns for mathematical arrays that put fewer restrictions on the data and can work in any number of dimensions unlike the conventionally widely used relational database management system model, in which each relation supports only one dimension of records.
