  3. NinJo architecture EGOWS 2004, Haucke, NinJo frameworks and software development process

  4. NinJo architecture • 3 main tiers : client, server, middleware • client tier: • NinJo client (GUI) • NinJo batch client • server side: data servers and services • event service • authentication service • import (data+products) • export (products) • monitoring and alerting • server side: science modules • OOG (guidance's) : under construction • cell/storm detection (planned) EGOWS 2004, Haucke, NinJo frameworks and software development process

  5. NinJo frameworks overview • NinJo is a building kit and a collection of applications as well • it consists of: • Frameworks on the one hand • Applications : independent windows or integrated components (Layers) on the other hand, with or without GUI (batch) • Applications use the frameworks and must follow unique design rules • Applications are special in respect to their special (main) data type, window layout, event handling and controlling (event based, time controlled,..) • Applications provide Gui components and concrete graphical representations of data • Frameworks itself use NinJo frameworks EGOWS 2004, Haucke, NinJo frameworks and software development process

  6. NinJo frameworks overview • The connection between frameworks, base implementations and runnable applications is the configuration • Configuration (XML) is the construction draft for the building kit • barely imaginable, how many variants of NinJo applications are possible • NinJo is configuration driven: • NinJo can start with one window, containing several maps or with just a window containing a Meteogram, as well as with lots of windows on several displays - only a question of the used configuration EGOWS 2004, Haucke, NinJo frameworks and software development process

  7. NinJo frameworks overview • What do we call a framework in NinJo context? • A separate software module (or sub tier) inside NinJo client • Similar to a software library or API • Consists of interfaces and base classes • Based on other NinJo frameworks and existing JAVA classes • Is used by several applications inside NinJo • Implementation of the frameworks is most generic • They are configurable themselves (even the configuration manager) • How to ensure the usability of the frameworks? • follow the OO design patterns and standards • configurability with XML • template pattern for compatible applications • MVC pattern for PAC agents • backward compatible extensions and changes EGOWS 2004, Haucke, NinJo frameworks and software development process

  8. NinJo frameworks overview • 3 kinds of frameworks • common : used by client and server applications • configuration • error handling and logging • Id (unique identifications for data types, elements ..) • i18n • client access layer (data access) • math (algorithms, projections) • communication • units • concurrency (threads) EGOWS 2004, Haucke, NinJo frameworks and software development process

  9. NinJo frameworks overview • server : only used on server side • basic server implementation • import system • client : only used on client side • PAC (Presentation Abstraction Control: the building kit for client applications) • PAC basic framework • derived : Layer framework • derived : diagram framework • derived : application (Toplevel) framework • GOF (graphical objects factory) : 2d, 3d graphics, several devices • vislib and visualizers : technical visualisation • GUI standard components EGOWS 2004, Haucke, NinJo frameworks and software development process

  10. NinJo client frameworks - new features • PAC (Presentation-Abstraction-Control) • 3 level agent hierarchy • BottomLevel (Layers) • Intermediate level (diagrams, charts, layercontainer) • Toplevel : applications like: Mainwindow, CrossSection, SingleScene • different implementations of each level possible • GUI of the client is composed by the Views of the agent hierarchy recursively • layout management for batch products and printouts • properties and base configuration - see PAC diagram framework • multithreading support (NjJob) • support for creation of Toplevel Agents (= Applications) EGOWS 2004, Haucke, NinJo frameworks and software development process

  11. NinJo client frameworks - new features • client access layer (client/server-communication) • jar file service • data cache • cache API • sharing data between components • faster data access • less memory • configurable • GOF • unified GOF : usage of 2D/3D now transparent • same methods and classes for 2d and 3d • animated canvas for animations • exportable canvas for export of graphic to file formats (PostScript) • overlay functionality added (for the dragging of objects) EGOWS 2004, Haucke, NinJo frameworks and software development process

  12. NinJo client frameworks - new features • GUI • form layout usage (JGoodies) • standard components: • JFontChooser • Input fields • spinner button • ColorChooser • Editing of data • modification • deletion • write back to the server or file system EGOWS 2004, Haucke, NinJo frameworks and software development process

  13. NinJo server frameworks - new features • new: export system • generic • trigger, reader, writer • Zip/Jar as virtual filesystem - useful for • MetObjects server • Configuration server • under construction • NinJo Naming Service • introduction of authentication, authorisation • event service EGOWS 2004, Haucke, NinJo frameworks and software development process

  14. framework changes- avoid migration effort • architectural principle: separation of concerns • change the fwk’s backward compatible • use interfaces for decoupling of objects • “extensions” for PAC • we invented the “extensions” for PAC • editing extension • cross section extension • 3d extension • add new functionality to frameworks without migration effort for the applications • only those applications, which want to contribute to the extension, have to implement something EGOWS 2004, Haucke, NinJo frameworks and software development process

  15. NinJo client applications • What is a “client application” in NinJo? • a collection of classes and configurations • can be aggregated to an existing application (if Bottomlevel or Intermediatelevel) or act as a standalone application (if Toplevel) • can aggregate other components • has an own configuration • can be installed separately • NinJo can start with only one or with more Toplevel application(s) • How to create a “client application” in NinJo? • use the frameworks • derive from basic applications • implement the special part (visualisation, data container classes) • follow the architectural patterns and templates • create a configuration EGOWS 2004, Haucke, NinJo frameworks and software development process

  16. NinJo client applications • client (NinjoMain) configuration example <?xml version="1.0" encoding="UTF-8" ?> <NinJoCfg> <!-- configuration of a toplevel agent --> <sceneControllerRef name="app" hasGUI="true" className="org.ninjoworkstation.client.appl.mainwindow.ControllerImpl" configName="training_workspace_mar_11_2004"/> <!–- optional more toplevel agents --> <sceneControllerRef name="app" hasGUI="true" className="org.ninjoworkstation.client.appl.singlescene.ControllerImpl" configName="empty"/> </NinJoCfg> EGOWS 2004, Haucke, NinJo frameworks and software development process

  24. NinJo - management of work in distributed teams • Tools - Perforce for source and document depot EGOWS 2004, Haucke, NinJo frameworks and software development process

  25. NinJo - management of work in distributed teams • Tools - IDE, e.g. :Eclipse, IntelliJ or Netbeans EGOWS 2004, Haucke, NinJo frameworks and software development process

  26. NinJo - management of work in distributed teams • Tools - Apache Ant • generating of JAVA classes for i18n, configuration and CORBA • supporting the build process • compiling the JAVA classes • creation of JAR - files • generating of installation scripts from templates • generating of run scripts for servers and client from templates • see http://ant.apache.org/ EGOWS 2004, Haucke, NinJo frameworks and software development process

  27. NinJo - management of work in distributed teams • Tools - Bugzilla : Bug tracking system EGOWS 2004, Haucke, NinJo frameworks and software development process

  28. NinJo - management of work in distributed teams • rules • well defined and documented software development process • starting with requirements specification for each component • Design document for each component • review process (and meetings) for documents and code • QM measurements • well defined software architecture , package structure and distribution of work • naming conventions : JAVA packages and Perforce labels • code freeze dates : for frameworks first, for applications later • branching the code lines after a release to ensure bugfixing possibility EGOWS 2004, Haucke, NinJo frameworks and software development process

  29. NinJo - management of work in distributed teams • framework and API development • developed by the best educated team members, supported by consulting • several locations develop frameworks, server or infrastructure components • locations, developing a framework, simultaneously develop at least one application ( to test the framework and to understand the application developers) • framework developers need tight contact to each other • communication • regularly CD meetings : meeting of all local chief designers • report of locations, planning the next steps and discussing / deciding architectural solutions • telephone conferences • emails EGOWS 2004, Haucke, NinJo frameworks and software development process

  30. NinJo - management of work in distributed teams • application development • each location team develops “his” components: • as few interfaces between the locations as possible to let the teams work independently as long as possible • full responsibility on all aspects of a component (e.g. layer), from data import on server side up to the visualisation • JAVA package structure : • if possible, only one team should develop inside one JAVA package • avoid “crossing” development • education • 1 week developers training, prepared by architecture team (CD) and framework developers (once a year) • train the usage of frameworks • train the usage of the tools • remind the software development process and quality standards EGOWS 2004, Haucke, NinJo frameworks and software development process

  31. NinJo Software development process and QM • 4 phases of software development process EGOWS 2004, Haucke, NinJo frameworks and software development process

  32. NinJo Software development process and QM • Quality management starts with the documents: • scheduling of QA tasks, 8 steps/measures • 1. requirements document • 2. test case description • 3. design document • 4. code review • 5. static analysis • 6. performance analysis • 7. test case results • 8. JAVA Help EGOWS 2004, Haucke, NinJo frameworks and software development process

  35. Preparing a release- working steps • code freeze : • each location: • check in the last changes • create the RfA- labels for frameworks and all applications: responsible are the distributed teams • integration phase • integration team: • synchronize the RfA labels in the predefined order • test the correctness of the labels • try the build process • build all client and server applications • create the Release label • Release label available EGOWS 2004, Haucke, NinJo frameworks and software development process

  36. Preparing a release- working steps • Perforce - synchronizing the Release label • Eclipse/IntelliJ/Netbeans..: run Ant script • select the “DVD” target • wait 5 minutes • find on the disc: DVD1 and DVD2 directories, containing: • whole NinJo software for server and client • whole configuration • installation scripts • templates for run scripts • copy the Geo data and (if needed) demo data • copy a JRE (JAVA runtime environment), inclusive extensions (third party Jar-files) • create the DVD images • burn the DVDs EGOWS 2004, Haucke, NinJo frameworks and software development process

  37. Preparing a release- working steps • automated release building with Ant EGOWS 2004, Haucke, NinJo frameworks and software development process

  38. Installing a NinJo release • directly from the DVD • Client • GUI driven : • just input the target directory • input the server name for live server • fully automated installation starts • demo servers • GUI driven : • just input the target directory • fully automated installation starts • for live server installation additionally • some manually configuration needed • configure the data import and delivery EGOWS 2004, Haucke, NinJo frameworks and software development process

  39.
