  1. Client Technologies Robert Gaul Eric Berryman Kunal Shroff

  2. Overview • Goals • Technologies • Control System Studio • Web Applications • APIs • XAL R. Gaul, Controls Database Collaboration, 18 Nov 2011

  3. Goals • Determine if the tools currently in use are the correct tools for the job • If not… then what are? • Standardize the chosen client-side tools between collaborators R. Gaul, Controls Database Collaboration, 18 Nov 2011

  4. In Use - Control System Studio • Currently using CSS for OPI screens and a handful of plugins (DataBrowser, Logbook) • Pros • Having a standard suite of tools readily available • Interconnectivity between plugins • Cons • Performance issues due to CSS being built on top of Eclipse • Steep learning curve for plugin development (easy to develop OPI screens though) • Need to leverage CSS expert knowledge R. Gaul, Controls Database Collaboration, 18 Nov 2011

  5. In Use - Control System Studio [2] R. Gaul, Controls Database Collaboration, 18 Nov 2011

  6. In Use – Web Applications • CakePHP • Pros • Resources are available within various FRIB/NSCL departments • PHP code can get very messy, this framework cleans things up a lot • Cons • Not the most friendly framework when using a web service as its data source • Workarounds can lead to bloated code • Google Widget Toolkit • Pros • Lots of ready to use widgets • Friendly with web services • Cons • Poor GUI development tools (GWT Designer) • No support for things such as multi-page web sites • Perhaps a java based framework would integrate easier in the larger picture of applications/services? A special thanks to Mengxuan Zhao for GWT information R. Gaul, Controls Database Collaboration, 18 Nov 2011

  7. In Use – Web Applications [2] R. Gaul, Controls Database Collaboration, 18 Nov 2011

  8. In Use –APIs • Each service we develop will also have an API associated with it • Java • Python • PHP • Others as requirements are defined • Pros • APIs can be thrown into applications for immediate use • A better interface for test driven development • Cons • A lot more initial overhead • Integration concerns R. Gaul, Controls Database Collaboration, 18 Nov 2011

  9. XAL • Physics modeling and computation front-end • Pros • Not tied to an IDE (such as Eclipse) • Easy to use for physicists • Cons • No interconnectivity between instances • Performance issues • Take advantage of the underlying data structures, models, and computational tools but use CSS as the front-end * A special thanks to Paul Chu for the information on this slide R. Gaul, Controls Database Collaboration, 18 Nov 2011

  10. Next Steps • Come to an agreement • Is what we have a good solution? What is the better route to go? • Discuss the chosen technologies thoroughly with programmers to hash out the technical details R. Gaul, Controls Database Collaboration, 18 Nov 2011
