20. Concepts Not everything is what it seems
21. What is a Course?
22. Calculus
23. Calculus Degree Student Teacher
24. Calculus Student Teacher What if the student flunks? Degree
25. Calculus Degree Student Teacher Calculus Execution Period Execution Course ! (e.g. 1st Sem. 11/12) Execution Course ! (e.g. 2st Sem. 11/12)
26. Calculus Degree Student Teacher Calculus Execution Period Execution Course ! (e.g. 1st Sem. 11/12) Execution Course ! (e.g. 2st Sem. 11/12) What if the Degree changes?
27. Calculus Degree Student Teacher Curricular Plan Calculus Execution Course ! (e.g. 2st Sem. 11/12) Curricular Course! (e.g. LEQ2006)
28. Calculus Degree Student Teacher Curricular Plan Calculus Execution Course ! (e.g. 2st Sem. 11/12) Curricular Course! (e.g. LEQ2006) Calculus never changes, why can’t I see from other curricular plans?
29. Calculus Degree Student Teacher Curricular Plan Calculus Execution Course ! (e.g. 2st Sem. 11/12) Curricular Course! (e.g. LEQ2006) Department Calculus Competence Course! Bible page 66
30. Calculus Degree Student Teacher Curricular Plan Calculus Execution Course ! (e.g. 2st Sem. 11/12) Curricular Course! (e.g. LEQ2006) Department Calculus Competence Course! Bible page 66 I want to have a teacher give the same classes to more than one degree.
31. Calculus Degree Student Teacher Curricular Plan Calculus Execution Course ! (e.g. 2st Sem. 11/12) Curricular Course Department Calculus Competence Course! Calculus Calculus Degree Curricular Plan Department
32. Student
33. Student Degree
34. Student Degree The student wants to change degrees
35. Student Degree Enrolment
36. Student Degree Enrolment How many semesters have the student done?
37. Student Degree Enrolment Registration Execution Period Calculus Execution Course !
38. Teacher Calculus Execution Course !
39. Teacher Calculus Execution Course ! Courses have more than one teacher and they have different responsibilities (e.g. hours)
40. Teacher Calculus Execution Course ! Professorship
41. Student Degree Enrolment Teacher Calculus Execution Course ! Professorship
42. Student Degree Enrolment Teacher Calculus Execution Course ! Professorship I have teacher assistants
43. Student Degree Enrolment Teacher Calculus Execution Course ! Professorship
44. Student Degree Enrolment Teacher Calculus Execution Course ! Professorship Who am I?
45. Student Degree Enrolment Teacher Calculus Execution Course ! Professorship Person
46. Student Degree Enrolment Teacher Calculus Execution Course ! Professorship Person Academic admin office needs to access the system
47. Student Degree Enrolment Teacher Calculus Execution Course ! Professorship Person Employee
48. Student Degree Enrolment Teacher Calculus Execution Course ! Professorship Person Employee User Bennu

52. Architecture
53. 12 Years Ago
54. Presentation Tier — Based on Struts Application Tier POJO’s Persistence Tier — Based on OJB XML Configuration Service Manager Services Filters XML! Configuration DTO’s XML! Configuration Data Repository JDBC JSP! Views Actions SQL Statements
55. The 11 “Simple” Steps 1. Create a POJO to represent the domain object; 2. Write the SQL schema to store the domain object; 3. Write the xml configuration to map the POJO against the SQL schema; 4. Write SQL statements for custom reading of the domain object (in case something other than a read by ID or a read all was necessary); 5. Create data transfer objects for passing information to the presentation tier; 6. Write services at the application level for creating, reading, updating and deleting the domain object; 7. Write access control filters to limit who can invoke services; 8. Write service and filter configurations in a xml file; 9. Create JSP views for presenting information to the users; 10. Write Actions to handle user requests; 11. Configure struts xml files to specify the application flow.
56. Presentation Tier — Based on Struts Application Tier Persistence Tier — Fenix Framework Based Service Manager Services Filters XML! Configuration Domain! Objects XML! Configuration Data Repository JDBC JSP! Views Actions DML Configuration
57. This allowed the application to grow
58. User Person
59. • Long compilation times • Large memory requirements • Poor expansibility • Poor encapsulation • It becomes easy to break domain constraints
60. Modularisation
61. Divide and Conquer
62. Persistence Tier — Fenix Framework Based Data Repository Fenix Application Request Controller Module 1 Presentation Tier Application Tier Domain Objects Module 2 Presentation Tier Application Tier Domain Objects ... Module N Presentation Tier Application Tier Domain Objects
63. Fenix Framework Bennu Framework Bennu Core Bennu IO Bennu Scheduler Bennu Portal Bennu Renderers Bennu Spring Bankai Angular Persistence Web Infrastructure Presentation Application Modules FenixEdu (IST) FenixEdu Id Cards FenixEdu Core
64. Domain Modularisation
65. Each module may define its own domain
66. Modular Presentation
67. Per-module presentation layer
68. Bennu Portal More on that later
69. How does this all come together?
