Longtime readers know that bringing some sense of architectural rigor to ITIL is an ongoing goal of this blog. The CMDB, viewed through an architectural lens, remains an ambiguous and challenged concept. Consider just two recent CMDB discussions:
"There is a very dual role played by the ODS. On the one hand, the ODS is decidedly operational. The ODS provides high response time and high availability and is certainly qualified to act as the basis of mission-critical systems. On the other hand, the ODS has some very clear DSS characteristics. The ODS is integrated, subject oriented and supports some important kinds of decision support...Because of the many roles that an ODS fulfills, it is a complex structure. Its underlying technology is complex. Its design is complex. Monitoring and maintaining the ODS is complex."
