7 CVS in Eclipse

8 Definition of Eclipse Eclipse is a universal platform for integrating development tools Extensible architecture based on plug-ins Plug-in development environment Java development tools Eclipse Platform PDE JDT Platform Standard Java2 Virtual Machine Java VM

9 Eclipse Platform Eclipse Platform is the common base Consists of several key components Eclipse Platform Workbench UI SWT JFace Team Help Debug Core Workspace Ant Platform Runtime

10 Eclipse inside structure Eclipse Platform Another Tool Java Development Tools (JDT) Workbench JFace SWT Help Team Your Tool Plug-in Development Environment (PDE) Workspace Debug Platform Runtime Their Tool Eclipse Project

11 Rich Client Platform

12 What is in RCP? While the Eclipse Platform is designed to serve as an open tools platform, it is architected so that its components can be used to build just about any client application. The minimal set of plug-ins needed to build a rich client application is collectively known as the Rich Client Platform. A subset of the full Platform There are other subsets

13 Example RCP apps IBM Workplace Client Technology NASA Space Mission Management BEA Workshop Lotus Notes ustudio

14 IBM Workplace Client Technology Dynamic, user-based provisioning Locked-down desktop Strong security requirements Restricted customizability

15 Maestro NASA Space Mission Management Responsive UI Open Platform for space mission monitoring Bringing together different teams in NASA/JPL

16 RCP of Eclipse Technologies system RCP components (base and optional) by theme: OSGi and Runtime UI SWT, JFace, Workbench, GEF, Forms Deployment JNLP, Update Manager Modeling EMF Tooling (PDE, VE, WTP)

17 Any components of Eclipse could be apply in RCP Eclipse Provides of RCP UI: -Views -Editors -Action sets -Perspectives -Wizards -Preference pages -Commands and Key Bindings -Undo/Redo support -Presentations and Themes

18 SWT - Standard Widget Toolkit Platform-independent native toolkit

19 GEF (Graphical Editor Framework) Draw2D - structured graphics drawing framework Graphical editor framework: MVC architecture Palette and common tools objects

20 EMF (Eclipse Modeling Framework) showing EMF models in JFace viewers enabling command-based editing editing model objects in the Properties page

21 Eclipse Help UI for RCP Application

22 PDE (Plug-in Development Environment) New plug-in project wizard with templates

23 PDE Product Export Product configuration and branding editor Can easily test and export from here

24 BIRT (Business Intelligence and Reporting Tools) Business Intelligence and Reporting Tools based on Eclipse Focused on embedded reporting for Java developers Eclipse Report Designer Web Based Report Designer Custom Report Designer Report Engine Custom Services 1 Report Design Engine 4 Data Transform. Services 2 Generation Services Charting Services Presentation Services 3 HTML PDF Print XML XML Report Design Data Report Document

25 Introduction to ustudio Universal GIS Desktop Application ustudio Team

33 Module Relationship

34 Detailed Relationship

35 Typical ustudio Architecture Web Pages userver(?)? ustudio GeoServer ubase

36 Compare with ESRI Architecture Web Pages ArcIMS ImageServer FeatureServer ArcSDE ArcMap

37 Integration with OpenGIS Specification Ability to directly view WMS Ability to directly edit WFS Ability to search catalogues Ability to integrate standard GIS data Hides complexity of network access

38 Introduction to GridGIS Lreis GridGIS Team

39 Theory -> Practice NOTE: As in the Internet, applications can use capabilities at any level of the stack. Abstractions are provided for convenience.

40 Grid and Web Services Grid GT1 GT2 Started far apart in apps & tech Web Have been converging HTTP WSDL, WS-* OGSI WSDL 2, WSDM? However, despite enthusiasm for OGSI, adoption within Web community turned out to be problematic

41 Grid and Web Services Grid GT1 GT2 Started far apart in apps & tech Web Have been converging HTTP WSDL, WS-* OGSI WSDL 2, WSDM WSRF The definition of WSRF means that Grid and Web communities can move forward on a common base

42 Globus Toolkit and WS-Resource Framework Improved robustness, scalability, performance, usability β β March Q2 Q3 Q WSRF specs 4.0 Numerous new WSRF-based services WSRF; some new functionality; further usability, performance enhancements Q1 05

43 Open Grid Services Architecture Domain-Specific Services Standardization Program Execution Core Services Data Services Open Grid Services Infrastructure Web Services Messaging, Security, Etc.

44 TeraGrid Project supported by NSF

45 TeraGrid Hierarchical Status Monitoring Groups tests into logical sets Supports many levels of detail and summarization Flexible, scalable architecture Very simple reporter API Can use existing test scripts (unit tests, status tools) Hierarchical controllers Several query/display tools

53 OGSA-DAI Service Organization

54 OGSA-DAI OGSA interface for accessing XML and relational data stores Implements the GGF DAIS WG standard (in progress) Client 1a. Request to Registry for sources of data about x 1b. Registry responds with Factory handle 2c. Factory returns handle of GDS to client 3a. Client queries GDS with XPath, SQL, etc DAI Service Group Registry 2a. Request to Factory for access to database Grid Data Service Factory 2b. Factory creates GridDataService to manage access SOAP/HTTP service creation API interactions 3c. Results of query returned to client (or to a 3 rd party) Grid Data Service XML / Relational database 3b. GDS interacts with database

55 Demo of OGSA-DAI Web Service

56 Future Research Direction ustudio: Java Development based on Eclipse platform, reliable stability and more features. Grid GIS : Data Access and Integration on various Geo-Spatial Database. Combination of Grid technology and Eclipse: New plug-in for grid service distribution.
