Hash
Data allocated in an algorithmically randomized fashion in an attempt to evenly distribute data and smooth access patterns.

Hierarchical Relationships
Any dimension's members may be organized based on parent- child relationships, typically where a parent member represents the consolidation of the members which are its children. The result is a hierarchy, and the parent/child relationships are hierarchical relationships.

High Availability
A protocol and associated execution that ensures a certain relative degree of computing-system operational continuity in any downtime event.

High-level Enterprise Model
A formal, high-level description in business terms of the information needed and used to manage the entire business, understood by business users and IS personnel.

Historical Database
A database that provides an historical perspective on the data.

HOLAP (Hybrid OLAP)
A product that can provide multidimensional analysis simultaneously of data stored in a multidimensional database and in an RDBMS. Becoming a popular architecture for server OLAP.

Horizontal Partitioning
Horizontal partitioning divides a single logical table into multiple physical tables based on the rows. All columns generally appear in the new tables, but each new table contains a subset of the original table's rows. The resultant tables may contain either discrete or overlapping subsets of the original table's data. Horizontal partitioning is employed when there is a regular need to access or to isolate a readily identifiable subset of the "parent" table's rows. This technique may be effective to meet security, distribution, and performance optimization needs.

Host-Driven
A processing method in which the host computer controls the session. A host-driven session typically includes terminal emulation, front ending or client/server types of connections. The host determines what is displayed on the desktop, receives user input from the desktop, and determines how the application responds to the input.

Householding
A methodology of consolidating names and addresses. Today, householding refers to any grouping of information about a given person, family, household or company

Hyper Text Markup Langage (HTML)
HTML, or Hyper Text Markup Language, a subset of SGML, provides a tag set used to create an HTML document. The tags or elements tell the browser how to display the information. The tags are used to "mark," in a hierarchical format, the different components of the document. If you are going to create your own Web pages, you will need to gain an understanding of the workings of HTML.

Hypercube
An OLAP product that stores all data in a single cube which has all the application dimensions applied to it.
