What Is Component-Based. Development? “Component-based development is the process of building systems by combining and integrating pretested and pre-engineered software components. ” Source: Application Development Trends, June 1996

Benefits of CBD w Faster development using pre-built components w Easier to maintain because the effect of change is restricted w Easier to create application variants and upgrades by replacing components w Cheaper development because of many uses of same component w Quality because many users of same component ensure quality

So … What Is a Component? w A component is an independently deliverable package of software services. Component XYZ

Facets of a Component Specification Implementation Executable

Component Models Each facet can be represented by models Specification Model Implementation Model Component XYZ Deployment Package

Specification w Logical Model w Clearly and precisely describes what the component will do for you w Descriptions make up the interface(s) to the component

Implementation w Physical Model w May or may not be the same as the Specification w Receives/returns information through the Specification

Executable Software Modules w Transactional executables (EXE) w Sub-transactional (OBJ/DLL) w Required data storage (DDL)

Another View of CBD w CBD is … n n n a different development method a different development culture a new kind of software market w CBD involves. . . n n n assembling applications from “software parts” building “software parts” trading “software parts”

Our CBD Approach w Includes methods and guidelines w Includes a standard for n n Specifying a component in Advantage Gen Delivering a component built using Advantage Gen w Includes component specific modeling tools

Methods and Guidelines w Route One in Advisor w CBD Express w e. Process w Gen Web w Various White papers

Component Standards w Standards are required for CBD w Three main standards: COM, CORBA, and EJBs w These tend to be. . . n n Language-specific for implementing components Target environment specific Developed with UI-oriented components Component semantics require trial-and-error use w Our CBD Standard n n Based on the Unified Component Model Technology Independent
