  1. Personal Tutor Architecture Review Peter Pratt/Lee Stobie/Defeng Ma/Morag Iannetta/Chris Giles/Frank Bergeret 22/04/2013

  2. Content • Current High Level Architecture • Issues/limitation/areas to be improved • What we have learned since last year • Suggested Architecture for the future • Action for next step

  3. Current Architecture for Personal Tutor System SITS eVision ColdFusion eVision DATABASE (STAR) Staff Inline Frame SITS Inline Frame Student STUDSUP Web proxy Read/Write Read only MyEd

  4. Additional Information for current Architecture • Data: two sets of data: • SITS schema: existing SITS data • STUDSUP schema: any other personal tutor data not from existing SITS • eVision: developed within eVision using SITS technology/processes; read/write to SITS schema, and read data only from STUDSUP • ColdFusion Application: Two interfaces with similar structure/components. User can access directly via URL. Read access to SITS, read/write access to STUDSUP. • Staff interface: for staff user. eVision page via inline frame • Student interface: for student user. eVision page via inline frame • MyEd • Student channel: web proxy for the student

  5. Issues/limitation/areas to be improved • It works now • But • Two applications (SITS, and ColdFusion App) put together via Inline-Frame. • No directly integration between them, and no interaction? • Number of support issues related to the layout (scrollbar etc.) • Difficult to expand for include further application/system/new function? • Need coordinate between the development work in two applications from two teams (SSP, SW DevTeam) • Using both applications require two skillsets for project/maintainance • Notification (email to PT) and done in CF. This could be advantage to do it outside eVision as they could be added into MyEd notification in the future. • Need more tests between two applications • Difficult for automated tests • The current architecture was based on the requirements, what our experience/knowledge with SITS/ColdFusion, and the resources available from IS Apps

  6. What we have learned so far • Using bootstrap framework to developer “facebook” like web applications with ColdFusion application • Bootstrap is adopted in the eVision (e.g. paperless admission) • Fix the issue with conflict between jQuery/Bootstrap within eVision • Student self service project working for the integration between eVision and MyEd • Deeplink into Task and SRL in eVision • SITS StuTalkfuncationality and interface API for integrating with other systems

  7. If we do it again • Given what we have developed until now, and what we have learned so far, will we do it in the same way? • Assumption: • Resource is available • We have time to develop it properly • We can throw the current version away, and build from scratch, thus no migration • The answer is NO, and a better architecture would be like the following

  8. Suggested Architecture for Personal Tutor System SITS eVision eVision DATABASE (STAR) SITS Staff StuTalk STUDSUP Student Web proxy Read/Write Read/Write via StuTalk MyEd

  9. Why it is better? • Data storage: no changes, SITS data in SITS, other data in STUDSUP. • Web proxy into MyEd for eVision (similar as before, but direct to eVision) • Build one application instead two, one design for the personal tutor application • SITS is preferred option (use of SITS data and access/reuse existing processes within SITS) • Use bootstrap framework to build the self contained application within eVision, and access the SITS data and STUDSUP data directly • Potential to use StuTalk within eVision to retrieve/store the data to develop re-usable function/component • Easy integration with other system/application via SOA/StuTalk • Can be extended for future requirements/development

  10. Next Step • Need spend more time to look at using StuTalk to improve the eVision functionality. A project is required. • Need look at what are planned for the future development for the personal tutor and decide whether it is now time to switch to new architecture • Need look at the resource impact on the time, and get people working together • Anything else?
