**6. Enterprise domains and aspects of the knowledge**

Having defined Knowledge-Based Enterprise architecture independently from the products the enterprise produces, the following knowledge management modeling approach is concerned with the identification of the types and actual content of the enterprise knowledge.


Table 1. Enterprise domains and aspects of the Enterprise knowledge

The investigations in knowledge management area are closely related with developments in the area of enterprise architecture (EA) frameworks (J.Schekkerman, 2003), enterprise modelling (EM) frameworks (Zachman, Sowa, 1992); (Maes et al., 2000); (Ulrich, 2002) and languages (Vernadat, 2002).

B. Iyer, R. Gottlieb decomposition of enterprise architecture (Iyer, Gottlieb, 2004) identifies four domains: business process domain, information/knowledge domain, infrastructure domain and organization domain.

Enterprise modelling (EM) and Enterprise architecture (EA) frameworks underlies our theoretical findings. In the contemporary EM and EA methods the three basic aspects of the enterprise knowledge *business strategy; business; information systems and technologies)* are separated, and used to construct layered architecture. The analysis of the EM methods is presented in (Gudas, Brundzaite, 2006).
