With Couchbase 4.0 and N1QL:
SELECT airline.callsign, route.from, route.to
FROM `travel-db` route
JOIN `travel-db` airline ON KEYS route.airlineid
WHERE route.from=`LAX` AND route.to=`SFO`

RETURN FLIGHTS FOR A PARTICULAR DAY
4. Foreach in “schedule”:
a. Does it match requested day? Y/N
b. Does it match requested day? Y/N
c. Does it match requested day? Y/N
d. Does it match requested day? Y/N
e. Does it match requested day? Y/N
f. Does it match requested day? Y/N
g. Does it match requested day? Y/N
5. Display matching day, route and airline
names
6. Throw away objects
For each requested route:
1. Read in “route” document from Couchbase:
a. Instantiate object
b. Handle errors
c. Manage memory
2. Parse JSON:
a. Map transcoder
b. Manage versioning
c. Handle missing values
3. Read in “schedule” object
a. Instantiate object
b. Handle errors
c. Manage memory
