Enterprise Architect (software)

Overview

Systems modeling using UML provides a basis for modeling all aspects of organizational architecture, along with the ability to provide a foundation for designing and implementing new systems or changing existing systems. The aspects that can be covered by this type of modeling range from laying out organizational or systems architectures, business process re-engineering, business analysis, and service-oriented architectures and web modeling, through to application and database design and re-engineering, and development of embedded systems. Along with system modeling, Enterprise Architect covers the core aspects of the application development life-cycle, from requirements management through to design, construction, testing and maintenance phases, with support for traceability, project management and change control of these processes, as well as, facilities for model driven development of application code using an internal integrated-development platform.

The user base ranges from programmers and business analysts through to enterprise architects, in organizations ranging from small developer companies, multi-national corporations and government organizations through to international industry standards bodies. Sparx Systems initially released Enterprise Architect in 2000. Originally designed as a UML modeling tool for modeling UML 1.1, the product has evolved to include other OMG UML specifications 1.3, 2.0, 2.1, 2.3, 2.4.1 and 2.5.

Modeling

Underlying UML modeling are several key aspects that most modeling tools support. The core aspects supported by Enterprise Architect include:

Profiles

Patterns

MOF

OCL

MDA Transforms

Corba IDL

UML Validation can be run against the model.

Requirements management

The common features of Requirements Management supported by Enterprise Architect include customization of how requirements are documented, linking requirements to the design and implementation details, and providing Requirement Traceability through the design and construction phases. These requirements can be subject to change management, workflow processing, baseline comparison and auditing.

Business modeling and analysis

Enterprise Architect supports a number of methods of modeling business processes using UML as the foundation modeling language. The core languages for business modeling and analysis include BPMN and BPEL, with various historic profiles such as the Eriksson-Penker profile. Enterprise Architect also supports the definition of Business Rules with the ability to generate executable code from these rules. Business modeling can be combined with Gap analysis to view potential gaps in proposed solutions.

Simulation

Model simulation is supported for:

Behavioral Diagrams:

State Machines

Interaction (Sequence diagrams)

Activities

Execution flow is defined using Triggers, Guards and Effects. The simulation supports re-runs with alteration to the triggered events and supports viewing variables, the call stack and setting debug markers. There is also support for interaction with emulated User-Interface screens containing common UI fields.

BPMN Diagrams:

Using BPSim - BPMN models can be simulated creating tabulated results for analysis.

SysML Parametric Simulation:

Using Open Modelica, mathematical formulas in SysML Blocks and Parametric Blocks can be simulated for plotting graphs used in analysis.

System development

In line with the Model Driven design principles Enterprise Architect supports MDA transforms of PIM Class structures to PSM Class structures, Round-trip engineering of code for 10 software languages and several key embedded HDL systems languages (Ada, VHDL and Verilog). It also supports code generation from Behavioral models.

Languages supported:

ActionScript

C

C# (for both .NET 1.1 and .NET 2.0)

C++(standard, plus .NET managed C++ extensions)

Delphi

Java (including Java 1.5, Aspects and Generics)

PHP

Python

Visual Basic

Visual Basic .NET

In accordance with Model Driven Development principles, Enterprise Architect provides an Integrated Development Environment that supports code editing (with Syntax highlighting and Intellisense), for Building, Debugging and Code Testing all from within the model. Compilers and interpreters supported:

Microsoft Windows Native C

Microsoft Windows Native C++

Microsoft Windows Visual Basic

Microsoft .NET Family (C#, J#, VB)

Sun Microsystems Java.

PHP

GNU Compilers for C++, C and Ada (GCC & GDB )

Add-ins are available for integration with MS Visual Studio and Eclipse.

Wireframing

Wireframe modeling supports using templates for modeling the appearance of dialogs presented to users when interacting with an application. The supported device dialogs include:

Screen Dialogs

Webpages - to model how the web pages work

Android Phones and Tablets

Apple iPhones and Tablets

Windows 8.1 Phones

Test management

For code based testing there is support for:

xUnit Testing

This involves MDA transformation of Classes to NUnit or Junit Classes with the ability to generate unit tests from the model and automatically record the results against the tested Classes.

Testpoint testing

This is a model based code testing. It is parallel to test contracts defined in ‘Design by Contract’ and it runs using debug definitions.

Both of these methods support the test definitions and test results being logged against related Classes in the model.

Visual execution analysis

Integrated with building and debugging code Enterprise Architect allows the developer to perform abstract analysis of the software using Profiling and Sequence diagram generation:

Sequence diagram generation provides a means to analyze the general process flow and iron out inconsistencies

Profiling summarizes, by thread and routine, the code's general efficiency

System engineering

System Engineering is supported with SysML 1.4 modeling which can be coupled with executable code generation. SysML supports modeling from requirement definition and system composition using SysML Blocks and Parts, through to parametric model simulation. The executable code generation supports embedded HDL system languages (Ada, VHDL and Verilog), or it can be coupled with behavioral code generation of the standard code languages defined above.

Data modeling

Enterprise Architect supports Data Modeling from the Conceptual to Physical levels, Forward and Reverse Engineering of Database Schemas, and MDA transformation of the Logical (platform independent) to Physical DBMS(platform dependant). Diagram types supported include:

DDL notation

ERD notation

IDEF1X notation

Information Engineering notation

om/

Change management

The key facilities supporting change management are:

Auditing

Baseline Difference and Merge

Version Control

The auditing feature supports logging changes to the model. The Baseline Management feature allows snapshots of parts of a model to be created periodically. A baseline can be compared and merged with the current model or a branch of that model. This supports Branching model information to another repository, then adding updates and merging them back.

The Version Control interface supports the major version control applications:

Subversion

CVS

Team Foundation Server

SCC interface to any SCC compatible version control system.

Integration with other tools

Features that support integration with other tools include:

XMI Import/Export: Supports the XMI 1.1, 1.2 and 2.1 specifications (and import of .emx and Rhapsody files)

Open Services for Lifecycle Collaboration (OSLC)

CSV Import/Export

ArchiMate Open Exchange Format Import / Export (from version 13)

Automation interface – supports a comprehensive API interface for use with any COM based language (and Java).

Among the Add-ins available are interfaces to VS .Net and Eclipse, Microsoft Office and DOORS, along with third party add-ins for interfacing with the likes of Jira.
