  2. Component Orientation Overview • Introduction to Scripting Languages • Component Software Architecture • Componentware & Object Orientation

  3. Scripting Languages • Scripting is Known as connecting different existing components to achieve a new related task. • Scripts serves as a "glue" allowing existing software (e.g., components) to be incorporated into application configurations.

  4. Scripting Languages • The combined component obtains common specifications from the constituent component. • If the components have similar specifications they can function with no need of additional coding. • This is frequently known as plug-and-play integration. • When they are executed at runtime, it becomes a form late binding.

  5. Scripting Languages • In some cases of large-scale development, a scripts and a lower level programming languages are combined to provide particular strengths. • Also are commonly used for developing graphical user interfaces (GUI’s) • Scripts are usually stored in the form of plain text and interpreted, or compiled when they are invoked. • Some Script Languages are JavaScript language, Visual Basic and TCL shell programming languages.

  6. Component Software Architecture • Software architecture is concerned with the planning and maintenance of system structure. • As an example of a what is considered a good architecture, a system structure should have room for changes in requirements and technologies. • Reusable components can accommodate changes to guarantee the continuous satisfaction during the life cycle of a system.

  7. Component Software Architecture • Software architecture offers the design context within which components are designed and reused. • An important characteristic of software architecture for componentware is the ability to support distributed project teams. • Software architecture contains a system specification that allows parallel, independent development of the system or its components.

  8. Component Software Architecture • Appropriate software architecture identifies computational boundaries that segregate the system into subsystems that can be tested by themselves. • These subsystems can be outsourced to one or more distributed project teams.

  9. Componentware & Object Orientation Componentware have four overlapping principles with object orientation:

  10. Componentware & Object Orientation • Componentware don’t give the same importance to inheritance as object orientation does. • As an alternative, instead of inheriting from other objects, functionality reuse is accomplished by invoking or delegating components.

  11. “Componentware technologies provide sophisticated approaches to software development that challenge outdated assumptions” • “Componentware represents a fundamental change in technology as object orientation did in previous generations” By Raphael Malveau, Thomas J. Mowbray.
