ah, the good old days of data processing - the days when unix developers worked on unix, windows developers worked on windows, and mainframe developers stuck to the big iron. in those days, each group could gather around its own water cooler and make fun of the developers working on the other platforms.
the unix team would make fun of windows reliability; windows developers would make fun of the mainframes outmoded technology; and the mainframers didnt care because they controlled the companys mission-critical business applications. developers simply never talked to each other. then along came websphere and everything changed.
websphere provides a standards-based application environment in which data and functions can be shared across applications. empowered users access necessary functions and data regardless of the datas location or the applications operating platform. users can enable their crm system to display current order status from the billing system, work-in-progress information from the production control system, or the order history for a particular customer across all divisions and subsidiaries. todays it buzz is about how this form of greater enterprise application integration (eai) can dramatically improve the productivity of an organization by providing universal, secure access to critical business functions and data to end users through simple, familiar interfaces. websphere provides the infrastructure to make eai happen.
websphere and the challenges of greater eai
to successfully implement eai using websphere, however, requires changes in how it has traditionally operated. as usual, making things simpler for end users complicates the work of it. it staff members can no longer operate in their isolated, platform-based silos. suddenly, everyone has to communicate and collaborate. changes to the mainframe database might require changes to the unix applications using the data or to the windows applications displaying it. new application fu... 下一页
