Questions tagged [multivalue]

The term "multivalue" refers to a nested data structure where a data column in a database table can contain multiple levels of nested columns.

In some databases, such as the namesake MultiValue database, an example of which is UniVerse, a number of top-level columns can be associated with each other, so that the data in, for example column 1, sub-column 2 has a direct relationship with the data in column 2, sub-column 2.

An example structure could look as follows:

Column one being order numbers, column 2 being order dates and column 3 being part numbers:


Column 1: 00001]00002]00003
Column 2: 26/07/12]27/07/12]28/07/12
Column 3: P123^P124]P125]P126

Multivalue data structures can often lead to excellent performance, one of the reasons being that they eliminate the need for resource consuming table joins.

Apart from the original MultiValue Databases, other examples which use multivalued data structures are many of the NoSQL databases and many Business Intelligence and Reporting tools.
