What IBM Rational Software Architect Designer is
IBM Rational Software Architect Designer uses graphical models to help teams understand, discuss, and communicate software designs. IBM describes support for preserving design intent and institutional knowledge, along with auditable evidence of policy conformance. Version 10.0 supports Java 17 modeling and transformations, including generating Java code from UML class diagrams. It also supports OpenAPI 3.0 enhancements for modeling endpoints and schemas and for generating or reverse engineering specification files. Rational SOMA 2.9 guidance covers service identification, specification, SOA realization, and service representation harvesting. A Deployment Planning extension provides topology templates and deployment models for deployment specifications. Integrations listed for version 10.0 include Jira, IBM Engineering Workflow Management, eGIT, ClearTeam Explorer, and WebSphere Portal Server tooling. The software supports Linux, Mac OS, and Windows, and works with Eclipse 4.23 or Vanilla Eclipse Workbench. Version 10.0 requires IBM Installation Manager 1.10.1.0 or later and 10 GB of disk space. Pricing is available from IBM on request.
