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