  5. WSS On­line Plus In­ter­net Front­end


The main challenge facing the Deutsche Börse AG (DB-AG) was the modernization of a host application within a relatively tight timeframe and budget, in order to comply with current customer requirements.

Our expertise with the design and development of individual solutions and our concept based on the orchideo framework of our implementation partner eXXcellent Solutions ensured the customer was convinced of our capabilities. The project, which was commissioned at a fixed price, was completed in line with time, cost, quality and scope requirements.

Technical Framework

In WSS On­line Plus, in­for­ma­ti­on on se­cu­ri­ties from va­rious or­ga­niza­t­i­ons are brought to­ge­ther and made avail­able to the cust­o­m­ers of DB-AG for the pur­po­se of re­se­arch. In the for­mer web-ba­sed so­lu­ti­on, the­re was a lar­ge quan­ti­ty of pre­de­fi­ned se­arch screens, re­sults lists and de­tai­led dia­log screens for the re­se­arch ac­tivi­ties.

New solution requirements

The exis­ting ap­p­li­ca­ti­on of­fe­red only a small num­ber of con­fi­gu­ra­ti­on op­ti­ons. Chan­ges of­ten lead to a lot of im­ple­men­ta­ti­on work. A so­lu­ti­on was the­re­fo­re nee­ded, which enab­led the data mo­del to be ad­jus­ted sim­ply by the spe­cia­list de­part­ments in line with chan­ges made to the de­li­ve­r­ed data. At the same time, cust­o­m­ers of DB-AG should be pro­vi­ded with spe­cia­li­zed views.

Fur­ther­mo­re, cross-sec­tio­nal func­tions were also nee­ded, such as a de­tai­led per­mis­si­ons sys­tem, a bil­ling sys­tem, the asyn­chro­nous de­li­very of re­se­arch re­sults via e-mail and nu­merous va­lue-ad­ded ser­vices. The new ap­p­li­ca­ti­on should also be rea­li­zed as a web ap­p­li­ca­ti­on, in the form of a mo­dern AJAX ap­p­li­ca­ti­on with a cut­ting-edge de­sign.

Ap­proach and be­ne­fits of the new so­lu­ti­on

In or­der to pro­vi­de a fle­xi­ble data mo­del with the abili­ty to make chan­ges ea­si­ly via the spe­cia­list de­part­ment, a mo­del-ba­sed ap­proach was cho­sen. The meta mo­del con­ta­ins all in­for­ma­ti­on for da­ta­ba­se ac­cess, na­vi­ga­ti­on wi­t­hin the data, ru­les for vi­sua­liza­t­i­on and much more. All vi­sua­liza­t­i­on dia­lo­gues were crea­ted in a way that ma­kes use of the in­for­ma­ti­on of the meta mo­del. This re­du­ced the amount of user-spe­ci­fic lo­gic that nee­ded to be im­ple­men­ted.

A de­sign com­po­nent was crea­ted ba­sed on the meta mo­del, which enables the spe­cia­list de­part­ment and the users to de­fi­ne new, spe­cia­li­zed views. The­se can be ad­jus­ted in line with the pro­blem area of the user.

This enables the user to make use of the re­qui­red data much more ef­fec­tive­ly, which is re­flec­ted in the quan­ti­ty-ba­sed bil­ling of the data. For DB-AG, this me­ans si­gni­fi­cant­ly fe­wer ad­just­ments, as no chan­ges to the ap­p­li­ca­ti­on are nee­ded if chan­ges have been made to the de­li­ve­r­ed data struc­tu­res. Most of the fo­re­see­able re­qui­re­ments can be im­ple­men­ted by the spe­cia­list de­part­ment by con­fi­gu­ring the meta mo­del.


  • Heavily used system with up to 2,500 simultaneous users
  • Heterogeneous technology environment (clients and server) with heterogeneous data
  • Resource limits (RAM, CPU) on server side vs. Desktop emulation on the client side

Technologies used

  • IBM WebSphere Application Server
  • IBM DB2
  • eXXcellent orchideo

Where do we go from here?

One re­qui­re­ment of the Deut­sche Bör­se Group is that they are able to fur­ther de­ve­lop the so­lu­ti­on them­sel­ves. This was achie­ved on the one side through the use of the or­chi­deo frame­work, that is ba­sed on com­mon open sour­ce stan­dards. On the other side, the se­pa­ra­ti­on of the meta mo­del and the tech­ni­cal im­ple­men­ta­ti­on mean many sys­tem ad­just­ments can be made wi­thout in-depth tech­ni­cal know­ledge.

EXXETA contribution

  • High level of expertise of EXXETA in relation to the design and development of individual web applications combined with the orchideo Framework of the EXXETA implementation partner, eXXcellent Solutions, which meant the project could be concluded successfully on schedule and within the budget for a fixed price, while taking quality and scope into consideration
  • Implementation based on common open source standards mean the customer can further develop the solution itself


“Host applications can be rejuvenated with modern GUIS for a reasonable price. The professional development of structured solution models (meta model views) is a decisive additional benefit of this provider. The end result is fast, reliable and user-friendly.”
