These supporting products and utilities must be developed and
designed to evolve with the current priorities and technical solutions avail-
able. Data and data services can be modified and enhanced in a modular
manner such that, as new technologies and products emerge, segments
can be swapped in and out as warranted by the business.
Products and tools provide the following execution services for EDM:
process execution, data identification, data sourcing, data extraction, data
storage, data transport, data acquisition, data control, and data services
management.
EDM BENEFITS
The benefits of EDM are both tangible and intangible. The quality of data
distributed by the EDM is consistently accurate, timely, and synchronized.
Access to this data is transparent to the end user and applications. The
iterative methodology and data reuse approach fosters quicker deliver-
ables by a reduction in the development cycle through the recurring use of
the single logical data resources and processes.
Among the intangible benefits of EDM is that it provides a common
source of information to be used by the corporation in processing its oper-
ations and making business decisions. The synergism attained by having
all functions access and retain information in a common data store
improves decision-making processes and allows the system to be more
responsive to the needs of the business.
EDM reduces:
• Code and data redundancy. This is managed at the data level, eliminat-
ing application re-creation of like elements and fields.
• The effect of input data. This is controlled from operational data sourc-
es with single update for all data stores and subsequent use functions.
• Processing requirements. This is needed only once because not all ap-
plications and users repeat data development and extract processes.
Conversely, EDM provides:
• Consistency of data names and definitions. It ensures that a common el-
ement is available for all applications and end users.
• Enhanced data integrity and currency. This ensures consistency in ac-
cessing a single data element or field.
• More timely data delivery. This ensures the downloading of this com-
mon element is provided as part of EDM to the application or end user.
• Improved quality of information available to the business. This ensures
consistency in meaning, updates, delivery, and contents of data.
• Improved quality and performance in accessing business. This ensures
consistency in access, catalog, and extract of data to end users.
