Enterprise Architect is available for purchase in four Editions:
- Ultimate
- Unified
- Corporate
- Professional
The functionality for each Edition is described here; the features of and differences between the Editions are listed in the table provided on the Sparx Systems website.
To help you understand the differences between these Editions and the advantages and limitations of each, you can open and use the Trial Edition of Enterprise Architect to mimic any of the Editions.
Edition Comparison
|
Ultimate Edition 
|
The Ultimate edition is designed for power users and those working across multiple domains, providing deep support for Business, for Software Engineering and for Systems Development, seamlessly integrated into a single development environment. It enables you to drill down to the lowest levels of systems design and construction, with SysML and executable code generation for standard and hardware description languages. Business users can leverage BPEL, the Rules Composer and executable UML, in addition to all the advanced features of the other editions of Enterprise Architect. Software developers can integrate their Eclipse and Visual Studio projects with their UML models and leverage the advanced executable code generators to target different domains. The Ultimate edition provides end-to-end traceability throughout a global vision of your enterprise - unifying strategy, business process, interfaces, software, rules, data and fine grained systems; advanced tools, domain-specific technologies, frameworks, integration platforms and a consistent, scalable, and robust interface work in unison to help you deliver on the promise of Model Driven Development. The Ultimate edition incorporates a number of MDG Technologies and Add-Ins; the Ultimate edition and the MDG Technologies are all available in either Fixed License or Floating License form. The Floating License arrangement is particularly useful for companies that manage a central store of license keys, which can be used by different employees over time, temporarily or permanently. The Ultimate edition provides:

Unified Edition 
|
The Unified edition is aimed at software development professionals, business modelers, architects, requirements experts, project managers and others involved in the design and construction of quality software and business services as well as systems engineers working on real-time, embedded and systems solutions. The Unified edition combines advanced features such as generation of executable code from UML models (including support for hardware languages such as Verilog and VHDL), Ada, SysML 1.5, executable SysML Parametric diagrams, BPEL, advanced scripting and a multi-purpose Rules Composer targeting executable code from Business Domain models. This edition bundles licenses for integration products and frameworks such as UAF (UPDM, DoDAF-MODAF), TOGAF and Zachman as well as SysML and DDS, to provide advanced model-driven construction tools to tightly bind your code development in Eclipse or Visual Studio with the UML/SysML models developed in Enterprise Architect. It provides additional features such as:

Corporate Edition 
|
Aimed at larger development teams, the Corporate edition enables you to connect to these DBMS back-ends as the shared repository:
This provides additional scalability and improved concurrency over the shared .eap/.eapx file approach to model sharing. User security, user logins, user groups and user level locking of elements, user/group based security (with locking at diagram and element levels) are also supported. Security comes in two modes: in the first mode, all elements are considered 'writeable' until explicitly locked by a user or group; in the second mode, all elements are considered locked until checked out with a user lock. The Corporate edition forms the base for the Unified and Ultimate editions; like those editions, it is available in either Fixed License or Floating License form. The Floating License arrangement is particularly useful for companies that manage a central store of license keys, which can be used by different employees over time, temporarily or permanently. |

Professional Edition 
|
Aimed at developers and engineers working alone or in small work groups, the Professional edition supports file-based model repositories, unsecured shared repositories and Firebird-based Cloud repositories. This Edition has an ActiveX interface for interrogating Enterprise Architect projects and extracting information. The Professional edition fully supports code import/export and synchronization of model elements with source code; it enables reverse engineering of SQL Server, MS Access, MySQL, PostgreSQL and Oracle databases. Support for MDG Technologies (sold separately) is included with the Professional edition. |
