2. Software Product Families, Software Product Lines, and Software Factories 21

3. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 3 Software

   Product Family § A group of related systems or applications sharing a common set of features manufactured from a common set of core assets. § Develop: Manufacturing (several) vs Craftmanship (one) § Reuse: systematic vs opportunistic (copy/paste)

4. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 4 Software

   Product Line Create a collection of similar systems (a family), through an assembly process, from a common set of assets following a common architecture Goal: § productivity, § quality and § evolution capability

   Product Line Create a collection of similar systems (a family), through an assembly process, from a common set of assets following a common architecture

6. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 6 Example

   | FaceView § Face face = new Face(); // … § ClientEngine dataSource = ClientEngine(); dataSource.start(); dataSource.addObserver(face); this.add(face); // … § public interface Face // extend Observer{ // parser // paint }

7. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 7 Software

   Factory A software factory is a software product line supported and configured for a particular domain with tools and processes.

    Factories § Abstraction (Features). hide complexity; emphasize characteristics; features to model to code. § Granularity (Size). Coarse grained components. (more functionality and fewer dependencies) § Specificity (Scope). Separation of commonality (core) and variability (optional).

16. Abstractions

17. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 17 Abstractions

    charts faces client server pushData popData console parser data UI client UI server

18. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 18 Abstractions

    parser charts face client server pushData popData console console data UI client data UI client

19. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 19 Abstractions

    § Face face = new Face (); § ChartView charts = new ChartView(); § ClientEngine engine = new ClientEngine(); § Console console = new Console(); § engine.addObserver(face); § engine.addObserver(charts); § engine.addObserver(console); § engine.start(); § UIClient view = new UIClient (face, chart);

20. Granularity

21. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 21 Granularity

    parser charts face client popData console data UI client

22. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 22 Granularity

    parser charts face client popData console data UI client

23. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 23 Granularity

    parser charts face client popData console data UI client

24. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 24 Granularity

    § Create a Contract public interface FaceInterface extends Observer { // variables ?? // new ?? public void update(Observable observable, Object object); public void paint(); }

25. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 25 Granularity

    § Apply a Contract public class myFace extends JPanel implements FaceInterface { public void update(Observable observable, Object object) { FaceData data = (FaceData)observable.getValue() } public void paint(); // drawHead(); // drawEyes(); // drawMouth(); repaint(); }

26. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 26 Granularity

    § What did you do to use jFreeChart? § What did you do to use javax.json?

27. Specificity

28. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 28 Specificity

    parser charts face client server pushData popData console console data UI client data UI client General vs Particular

29. Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 29 Specificity
