Modeling Application Usage Visually

Scott Barber
Scott Barber is the CTO of PerfTestPlus, Inc. and Co-Founder of the Workshop on Performance and Reliability (WOPR). Scott’s particular specialties are testing and analyzing performance for complex systems, developing customized testing methodologies, group facilitation and authoring instructional materials.

ABSTRACT
Modeling application usage is more than just parsing log files and calculating page frequencies. Whether we are analyzing navigation path effectiveness, planning for scenario testing, documenting performance test workload models or mapping services or objects to user activity having a single, intuitive picture to reference makes the job easier.

In this session, we’ll explore a highly adaptable method for visualizing application usage and how to use this model to improve cross-functional team communication without requiring team members to invest time learning some new fad of a modeling language that they’ll probably never use again. This method references UCMLâ„¢ which has been described as "what collaboration diagrams should have been." Read the rest of this entry »

Ruby Sig: How To Design A Domain Specific Language
Google engEDU
1 hr 3 min – Oct 5, 2006

Google Tech Talks
October 5, 2006

David Pollak has been developing commercial software for 28 years. He founded Athena Design and wrote Mesa, the first real-time spreadsheet. David wrote Integer, the first online, collaborative spreadsheet. Since 2000, David has been developing domain specific languages for security and general web development.

ABSTRACT
David will describe a framework for developing DSLs which includes:

* Identifying the constituents in a development project;
* Determining the costs and benefits of a DSL for a particular constituency vs. hand-coding functionality for that constituency based on interviews and specs;
* Identifying the ‘thought leader’ in a given constituency and interviewing him or her to determine the semantics of the domain;
* Determining syntax of the DSL;
* Mocking up the DSL and ‘test driving’ it with the thought leader;
* Finding appropriate integration points for the DSL into the application;
* Defining the process by with the Domain Experts will update code in the DSL (e.g., they have a web page where they can change tax calculation rules vs. they make a change to particular Ruby files as part of a development/staging/production cycle.); and
* Iterate over the semantics, syntax, and process to fully integrate Domain Experts into the development process. Read the rest of this entry »
