|
the mode of analysis in which the next step is determined by the results of the
current step of analysis.
|
|
|
The organization of data into a logical tree structure.
|
|
|
Within an enterprise, a network consisting of the same type of servers and
databases.
|
|
|
Hub and Spoke Configuration |
|
A configuration of interconnected systems where a single system (the hub) acts
as the central point for exchanging data with and between the other systems
(spokes).
|
|
|
Data that has been processed in such a way that it can increase the knowledge of
the person who receives it.
|
|
|
Information Systems Architecture |
|
The authoritative definition of the business rules, systems structure, technical framework, and product backbone for business information systems.
|
|
|
a set of values representing a specific property of a data base that ensures that the data contained in the data base in accurate and consistent as possible.
|
|
|
data from different tables mixed into a simple table space where is commonality of physical colocation based on a common key value.
|
|
|
the mode of processing in which the next step of processing depends on the results obtained by the existing step in execution.
|
|
|
an operation that takes two relations as operands and produces a new relation by concatenating the tuples and matching the corresponding columns when a stated condition holds between the two.
|
|
|
is often used to mean any delay or waiting that increases real or perceived response time beyond the response time desired.
|
|
|
After extracting, cleaning and transforming, data must be loaded into the warehouse. Additional preprocessing may still be required: checking integrity constraints; sorting; summarization, aggregation and other computation to build the derived tables stored in the warehouse; building indices and other access paths; and partitionaing to multiple target storage areas. Load utilities can be used for these operations.
|
|
|
the event that occurs when update is done against a data base record and the transaction has not yet reached a commit point.
|
|
|
the automatic recording of data with regard to the access of the data, the updates to the data, etc
|
|
|
a data view or description that does not depend on a physical storage device or a computer program.
|
|
|
Maximum Transaction Arrival Rate (MTAR) |
|
he rate of arrival of transactions at the moment of peak period processing.
|
|
|
The process of consolidating, relating and synchronizing data elements with the same or similar meaning from different systems. Metadata synchronization joins these differing elements together in the data warehouse to allow for easier access.
|
|
|
a language used to specify other languages.
|
|
|
A system of principles, practices, and procedures applied to a specific branch of knowledge.
|
|
|
To be scalable, any particular implementation of the data access environment may incorporate several intermediate distribution tiers in the data warehouse network. These intermediate tiers act as source data warehouses for geographically isolated sharable data that is needed across several business functions.
