Sequence diagrams are a very effective way of modeling an object oriented system. Unfortunately, most UML based modeling tools only offer primitive support for sequence diagrams. EventStudio provides advanced constructs for sequence diagram based object modeling. EventStudio supports generation of message sequence charts (MSCs) and call flow diagrams used in telecom and embedded system development. Process workflow generation is supported for business process re-engineering applications.
When modeling with EventStudio, developers describe the interactions in the system in terms of a simple declarative modeling language. EventStudio then analyzes the model for design errors, inconsistent operations, resource leaks and invalid timer operations. Once the design issues have been addressed, EventStudio automatically generates sequence diagrams and collaboration diagrams.

EventStudio allows the developers to explore a large number of success and failure scenarios without the overhead of individually documenting each scenario. The developers define a base scenario and then define other scenarios by just specifying the differences with the base scenario. EventStudio manages the scenario definitions and generates the documents by merging the base scenario with the specified differences for each scenario.

EventStudio automatically handles diagram layout, formatting, scaling and page breaks for sequence diagrams and collaboration diagrams generated in the Adobe PDF and Microsoft Word Picture (EMF) formats. This allows the developers to focus on system architecture and design, without getting bogged down by document layout issues.

EventStudio has been designed to handle diagram generation for systems with a large number of interacting objects. For greater modularity, objects in the system can be classified into groups and sub-groups. This classification is used to generate diagrams that focus on a particular aspect of the system.

QuickUML is a software design tool that tightly integrates a core set of UML models with code generation for several languages. An entire project is presented through a tabbed window that includes use cases, class models, object models, dictionary and code and saved as an XML file. Use cases document user interactions with the system and link to models, code, foreign files or other use cases. Class models may contain classes, interfaces, components, packages and other objects. Sequence diagrams illustrate how objects interact with emphasis on the order in which things occur. QuickUML contains advanced features for multiple language projects, design namespaces, UML stereotype extensions, flexible color support, custom detail fields and automated generation of class models from the dictionary. An integrated code manager enables the designer to navigate through code files linked to use cases and diagram objects.

QuickCRC is a tool for responsibility driven design of object-oriented software using CRC cards. CRC cards are used to discover and document classes, responsibilities, attributes and collaborations between classes. Design scenarios can be identified and simulated. Complex designs can be partitioned into multiple diagrams with easy navigation through a contents view. The inheritance graph automatically shows the class structure of the evolving design. The user can assign the attribute access of each card responsibility and the tool presents an attribute access graph.
