Two significant events have happened recently:
- IBM has rationalized its data-related middleware and put it under the heading of "information integration," as part of an "information on demand" strategy.
- The IBM System z9 folks have begun a strong strategy of positioning the System z9 as the premier platform for data serving.
How do the two relate? Or, to put it another way, how can IBM customers leverage both information integration and the System z9's new data-serving capabilities?
IBM's information integration solution set is less about the name and more about what customers can do with IBM's new data-related software architecture.
That architecture consists of individually useful capabilities, as shown below.

Example: Those in WebSphere DataStorage (formerly Ascential) & WebSphere Information Integrator
Combined, these information integration tools, on any platform, can play a key role in business-strategy success, as shown in Table 2. The "VOS" in this Table is a virtual operational store, combining ODS and EII, which acts as a "virtual" enterprise-wide database.

System z9 data serving
System z9's new data-serving capabilities, as announced on 1/24/06, have three components:
DB2 for z/OS improvements, in V8 and the forthcoming "vNext", include:
Of these, perhaps the most important is the support for a "superset" of standard SQL, so that most applications can access DB2 for z/OS (and IMS) or other databases with the same code.
zIIP is a specialty engine for the System z9 that allows outside applications to access mainframe data stores with high performance and the rest of the System z9's virtues. As IBM notes, zIIP allows such non-mainframe applications as ERP, CRM, BI, and data warehousing to access and take advantage of business-critical mainframe data much more easily. This, in turn, gives users a good reason to place more of their data centrally in a common repository, on the mainframe data server.
Other key data-serving features in system z9-109 include:
Marrying the two
The need to unite mainframe data serving and information integration stems from two long-time facts:
Until now, no one could do anything about this, for two reasons:
Thus, the two events cited above are key to marrying information integration and mainframe data serving:
In other words, using IBM's information integration tools and the latest System z9 technology, a user can much more easily "redirect" a business-critical application such as ERP, CRM, or BI to use mainframe as well as non-mainframe data, and store structured, semi-structured, and non-structured data equally on the mainframe or off it.
Fruitful areas to apply system z9 plus information integration
The marriage of information integration and System z9 also offers users the opportunity to employ a mainframe in new ways.
For example, users with mainframe data warehouses can now add semi-structured and unstructured data to these. Thus, the "extended data warehouse" that is often discussed these days will support more current data gathered from a greater array of data sources such as outside the organization on the Web, and BI applications that before could not access the mainframe's data or were forced to copy it frequently to another platform can gain richer insights with higher performance.
As another example, users in such efforts as "master data management" are now seeking to create metadata ("data about data") that establishes the relationships between all copies of related customer, supply-chain vendor, or distributor data. Much of this key data is on the mainframe; therefore, for performance's or simplicity's sake, it makes sense to place the repository of this metadata on the mainframe. The mainframe can therefore potentially be used as the focal point for an effort to rationalize the data architecture of the enterprise, with dramatic effects on IT costs, the ability to gain strategic insights, and react to events rapidly — "information on demand."
Of course, not all difficulties have been swept away. Customers should expect to have to carry out due diligence, formulate a process for incorporating key applications in the mainframe-information-integration marriage, and deal with the gritty details of implementation.
Nevertheless, I conclude that a mainframe-information-integration marriage is now, for the first time, real, and its potential achievable. In turn, that means that the mainframe is of greater strategic importance to the enterprise beyond its own boundaries, as an integral and by no means negligible part of overall IT information efforts. New ways to leverage mainframe data serving using information integration are nice for the customer; but leveraging the mainframe as part of an overall information strategy is even nicer.
