Abstract:
In the last several years, I've taken a different approach to building software applications. Implementing various application concerns(1) generically(2) has enabled me to reuse the implementations across projects.
- (1) concerns: such as forms construction, validation, ui navigation, search, authorization
- (2) generically: in such a fashion that the implementation is decoupled from, or agnostic from the application's domain
Specifically, I have constructed a framework that enables a very high degree of reuse, whereby I reduce application development to little more than defining the domain. Where implementations of the persistence, user interface, and other concerns can be reused across differing applications. In this talk, I will be sharing with you my experiences with this approach, and the results it has yielded. Live demonstrations of the various reusable features will be given.
Outline:
- Introduction (1 min)
- What's wrong with the way we build software applications today? (5 mins)
- The scaffolds we see in rails, grails, etc.. are the beginning (2 mins)
- Decoupling concerns implementations from the domain = Freedom to reuse implementations across applications (1 min)
- How to decouple the model: coupling to the metamodel (5 mins)
- Demonstrating sample applications constructed in this fashion (5 mins)
- Overview of Generic Implementations:
- Generic Create, Read, Update, Delete (2 mins)
- Deployment (5 mins)
- Analysis of the results (5 mins)
- Conclusions/References (1 min)
- Q&A (5 mins)
Language:
English
Level:
Intermediate
Required experience:
Participants should have experience in designing and implementing business software solutions. Code examples will be given using the following specific tool stack: the Java programming language, the Swing GUI Toolkit, the Hibernate O/R Mapping framework, and Java reflection, metadata concepts.
Expected audience:
Please consider attending this session if you are either a developer or manager with interest in exploring ways to improve the current state of software applications development in the areas of: developer productivity, usability, software application maintainability.

This talk is a reflection of Eitan's experiences with this approach of constructing software solutions in a fashion where feature implementations are decoupled from the domain.
