Data Warehousing
The Challenge: How to validate requirements before implementation
Depending on your definition of a failure, data warehouses have a significant to alarmingly
high failure rate. Data mart models can improve your odds, but not as much as you might hope.
In many cases, problems occur because the requirements change during implementation. In
others, the initial request is incomplete or inadequate, but this is not discovered until
after the implementation, when users start working with the warehoused data.
These issues are not unique to data warehousing, but they are exacerbated by the typically
long implementation cycle. One of the major factors affecting the length of implementation can
be integration with mainframe legacy data.
Prototyping is an approach often taken in other software development areas. What is needed
is a way of quickly prototyping your data warehouse or data mart. In this way you can validate
the requirements before you start your implementation.
This is exactly the opportunity that Arbutus LegacyLink™ presents!
The Solution
Arbutus specializes in accessing non-relational
legacy mainframe and AS/400 data. Arbutus
Integrate is
middleware specifically tailored
to move that data directly to a Windows environment. The solution
is simple, powerful, timely and cost effective.
Arbutus reads virtually any mainframe directly
and presents it as a virtual relational database, almost indistinguishable from a data mart.
This virtual database is instantly accessible by any Windows based application, without any of
the complexities you would typically encounter.
This means that you can prototype much of your data mart very quickly. Not only can you
validate the request, but you can work with the system for a period of time to discover any
additional requirements or to monitor query patterns.
In addition to accessing the data, Arbutus offers semantic
and transformation layers that allow the
implementation of virtually any data interface or business rule. You are not limited to merely
exposing the data, but can dynamically fit it to your needs.
Call Arbutus today, and let us show you how easy it is.
