This document discusses how CMDB (Configuration Management Database) data and EAM (Enterprise Architecture Management) tools like LeanIX can benefit each other. A CMDB provides a bottom-up inventory of technical components through automatic discovery, while an EAM tool provides a top-down view of the relationships between technology, applications, and business context. By combining data from both, organizations can ensure data quality, get a complete picture of their IT portfolio, and help execute their IT strategy. The document outlines challenges of solely using a CMDB and opportunities of integrating it with LeanIX, such as pre-filling data and regularly updating records.
