+# 1. Goal
+Show the air quality of each measuring station. A dashboard and an OData service
+will read the values, so the calculation must be in the database, in a CDS view.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- Table {{P}}STATION (measuring station), package $TMP. Key: STATION_ID (CHAR 10).
+  Fields: STATION_NAME (CHAR 20), LIMIT_PM (DEC 5,1, the permitted fine dust
+  value of the station).
+- Table {{P}}READING (single fine dust reading), package $TMP. Key: STATION_ID
+  (CHAR 10), READING_NO (INT4). Fields: PM_VALUE (DEC 5,1, the measured fine
+  dust value).
+
+# 4. Contract
+- Create the CDS view entity {{P}}I_AIR_QUALITY in package $TMP.
+- Elements, with these names: STATION_ID (key), STATION_NAME, READING_COUNT,
+  AVG_PM, MAX_PM, RATING, DEVIATION.
+- No authorization check (#NOT_REQUIRED).
+
+# 5. Business rules
+1. Show one row for each station that has at least one reading. Do not show a
+   station without readings.
+2. STATION_NAME is the name of the station.
+3. READING_COUNT is the number of readings of the station.
+4. AVG_PM is the average PM_VALUE of the readings of the station, with 1 decimal
+   place.
+5. MAX_PM is the highest PM_VALUE of the station.
+6. RATING is the class of the station:
+   - 'HIGH' if MAX_PM is greater than LIMIT_PM,
+   - 'MEDIUM' if MAX_PM is greater than 80 percent of LIMIT_PM,
+   - 'LOW' in all other cases.
+7. DEVIATION is the distance between MAX_PM and LIMIT_PM, as a positive number.
+
+# 6. Constraints
+- Release target: 8.16.
+- Coding standards: Clean ABAP. No ATC priority 1 or priority 2 findings.
+- Out of scope: do not change {{P}}STATION and {{P}}READING.
+
+# 7. Acceptance
+- The view is active and has no syntax error.
+- The hidden tests pass.
+- Write ABAP Unit tests with CL_CDS_TEST_ENVIRONMENT in a global test class.
