Case Study

Information subsystem for electric distribution remote control (IPS SDU)
Electric Utility of Belgrade

Starting from consulting services for Electric Utility of Belgrade Diginaut’s engagement outgrow expectations and become the largest installation of any ZORA system.

Decision for using, at that time fresh, third version of ZORA was made after accepting CIM model and IEC 61968 standards as framework.

Project specification described 1270 classes/documents and 7 user groups. Maximum number of forms for data presentation was estimating 9800! Clients request was to integrate, enhance or replace existing applications with the new system. It was decided to create IPSSDU prototype using ZORA 3 tools. Later system will be tested and fine-tuned during data migration using dynamic model driven environment (ZORA MDE).

In less than two months since completion of UML model, first version of IPS SDU prototype system was activated. UML model was adapted to current user needs and number of document was reduced to 680.

IPS SDU continuously works since 2002 without single unplanned stop.

User resistance for changes and new work environment at the beginning slowly changed to active participation in system development and integration with other systems.

Integration with applications for network presentation and monitoring was achieved by using ZORA web services and ZORA object instances (ZORA Entity Instance).

Most of the work on these tasks was done by three Diginaut engineers and several engineers from Electric Utility of Belgrade. ZORA MDE architecture has shown its potential and efficiency and gained considering trust by our clients and especially by us.

IPS SDU with its scale and with many innovations built into it, has improved ZORA environment. Development is continuing toward further integration with other systems.

AD Center (ADC)
Information system for advertising departments of printed and electronic media

During work on outsourcing project for our client, Diginaut created application for page layout of ads in the newspapers. Process of planning, analyzing and management of ad space was found very interesting testing ground for ZORA 2 as well as potential market for future products.

AD Center (ADC) project was started. It was not as interesting as target for modeling and automatic generation of system tiers, as its dynamic nature was appealing to MDE, runtime customizations and context based data presentation.

Decision to start the project was correct. Several user groups (environments) were created for ad reception, finance, design, prepress, agents, key accounts and managers. Data in these groups is presented and processed according to the needs of that group. Runtime analyzing of object relational database was especially successful part of the project. Users were very satisfied and soon ZORA 3 version of ADC was introduced.

Dozens of specific views and analysis per user groups allows good financial and organizational control of sales. Active components were adapted to the user environments allowing moving through data hierarchy from page layout to financial reporting.

ADC initiated development of online data processing components that can adapt data presentation to the user group they are activated in.

Object database architecture has shown that unavoidable redundancy was compensated by better control of many types of services (small, blocked, color ads, insertations, radio or TV commercials, etc) and easier reporting.
