agent consolidates different types of collected data. Missing values and incon-
sistencies are checked using information consolidation routines. When needed,
consolidated data is transformed according to the database scheme and finally
stored in the database. Data analysis and reports are generated according to the
stored user's profile using Structure Query Language (SQL).
Implementation of the proposed architecture is based on the Workflow Refer-
ence Model. This model, created by the Workflow Management Coalition (2006),
provides one possible standardization approach for workflow management sys-
tems, ensuring consistent understanding and implementation through the sepa-
ration of organizational structures and resources from application programs (or
code). Thus, project workflows are stored and retrieved separately, enabling cross-
project workflow integration (e.g. from different project data servers).
According to the Workflow Reference Model, the process information is stored
in the Workflow Engine. A relational database management system, accessible
through the Internet, is used as a DyCE workflow engine. IFC 2x process
specifications are used for relational database management schema (IAI, 2001).
Furthermore, layered process and data management known from practice (usual
in Slovenia) is adopted: the project manager defines and is responsible for the
general project workflow, each participating company (contractor) then follows
defined project constraints organizing its internal workflow, and within the
company's workflow each worker has the opportunity to arrange his project's
tasks. Therefore, three role-based management services provide these functional-
ities: General project workflow service, Company workflow service and Personal
