1. Goal
A training provider sells seats in courses. The booking program needs one service that answers three questions:
- How many seats are free in a course?
- Can we book a given number of seats in a course?
- Which courses of a category still have enough free seats?
2. Open questions
None.
3. Context
- The database table {{P}}COURSE exists in package $TMP. It has these columns: MANDT (client), COURSE_ID (CHAR 10, key), CATEGORY (CHAR 10), TITLE (CHAR 40), CAPACITY (INT4), BOOKED (INT4).
- CAPACITY is the number of seats of the course. BOOKED is the number of seats that are already sold.
- The class {{P}}SEED_COURSES fills the table with example data. It is active.
4. Contract
- Create the class {{P}}COURSE_BOOKING in package $TMP.
- The class is public, final, and has a public constructor without parameters.
- The class has these public types:
- TY_COURSE_ID, type C, length 10.
- TY_CATEGORY, type C, length 10.
- TY_COURSE_INFO, a structure with the components COURSE_ID (type TY_COURSE_ID), TITLE (type C, length 40) and FREE_SEATS (type I).
- TT_COURSE_INFO, a standard table of TY_COURSE_INFO with an empty key.
- The class has these public methods:
- GET_FREE_SEATS, importing IV_COURSE_ID type TY_COURSE_ID, returning RV_FREE_SEATS type I.
- IS_BOOKABLE, importing IV_COURSE_ID type TY_COURSE_ID and IV_SEATS type I, returning RV_BOOKABLE type ABAP_BOOL.
- LIST_BOOKABLE_COURSES, importing IV_CATEGORY type TY_CATEGORY and IV_SEATS type I, returning RT_COURSES type TT_COURSE_INFO.
- Do not add other public methods.
5. Business rules
Free seats
- Read the course with the course ID.
- If the table has no course with this ID, the free seats are 0.
- The free seats are the capacity minus the booked seats.
- If the capacity minus the booked seats is less than 0, the free seats are 0.
GET_FREE_SEATS returns the free seats of the course.
IS_BOOKABLE 5. If IV_SEATS is less than 1, the result is false. 6. If the table has no course with this ID, the result is false. 7. The result is true if IV_SEATS is less than or equal to the free seats of the course. Else the result is false.
LIST_BOOKABLE_COURSES 8. Read all courses with the category IV_CATEGORY. 9. Use only the courses whose free seats are greater than or equal to IV_SEATS. 10. Sort the result in ascending order by COURSE_ID. 11. Each result row has the COURSE_ID, the TITLE and the free seats of the course. 12. If no course matches, the result is empty.
6. Constraints
- Release target: 8.16.
- Coding standards: Clean ABAP. Method length below 40 statements. No global variables. No comment that restates the code.
- Out of scope: do not change the table {{P}}COURSE and the class {{P}}SEED_COURSES.
7. Acceptance
- The class is active and has no syntax error.
- The hidden tests pass.
- Write your own ABAP Unit tests for the class.
