Model application architecture the CSDM way.
A free, browser-only canvas for modeling application architecture with ServiceNow's Common Service Data Model. No sign-up; your models stay in your browser.
Five stacked layers, from Infrastructure at the bottom to Business at the top: the Host web-prod-01, the Application checkout-web, the Application Service Checkout — production, the Business Application Checkout and the Business Capability Order Management. Data rises between the layers.

// The same chain, three ways
- A Business Capability, Order Management, is provided by the Business Application Checkout, which uses the Application Service Checkout — production. That service depends on the Application checkout-web, which runs on the Host web-prod-01.Fig. 01The realization chainAllowed relationships only. Every rule cites its source.
- The same chain, with a line drawn straight from the Business Application Checkout to the Host web-prod-01. The editor refuses it: a Business Application is not related directly to a Host in CSDM. The route goes through the Application Service Checkout — production instead.Fig. 02Caught earlyA Business Application is not related directly to a Host in CSDM.
- The same elements read in ArchiMate 3.2: Order Management is a Capability realized by the Application Component Checkout, which is realized by the Application Component Checkout — production. The System Software checkout-web serves it, and the Node web-prod-01 aggregates the system software. Elements take their ArchiMate layer colors; the model itself stays in CSDM.Fig. 03Read it in ArchiMateSame model, read in ArchiMate 3.2: a view-only lens.ArchiMate® is a registered trademark of The Open Group.
