Objective

Definition

Our objective is to assist an engineer in developing a system based on asoftware system family by offering domain knowledge for reuse.

We provide assistance in developing a system in:

Offering obligatory and optional features of a system family

Automated analysis of systems for identifying requirements

Providing generation rules for realising particular features

Generating realising models upon a feature configuration

Generating code based on these models

Basics - Information Integration Systems (IIS)

Definition

An Information Integration System (IIS) provides a single read-accesspoint to a set of autonomous heterogeneous data sources.

Basics - Software system families

Definition

Software systems that share a particular reference architecture and havecommon and variant features belong to a software system family.

Conclusions

Domain Engineering vs. Application Engineering

Definition

Domain Engineering gathers domain knowledge reusable in any phasewhen engineering an application of a system family.

Feature Modelling

Definition

Feature Models are used to describe commonness and variety of systemsbelonging to a system family.

Conclusions

The framework supports:

MDA-driven Application Engineering + Domain Engineering +Continuous Software Engineering

Main properties:

Feature models specify properties of a system family

Patterns structure reusable domain knowledge

Support of all parts of the engineering (and evolution) process

requirements analysis: feature models & configurationsreverse engineering: system analysis / feature discoveryforward engineering: feature-driven generators (for applying patterns)
