Hi @vikramboorl
In Simple Model Category in CMDB is used to define the type of product.
For example, Computer, Server, Network Gear, Printer are model categories. A Model is a specific product under that category, like Dell Latitude 5420 under Computer. A CI is the actual item in your environment, like LAP-001, and an Asset is used for financial tracking of that same item.
In short: Model Category = product type, Model = specific product, CI = actual device, Asset = financial record.
