COMBINE ROUTE WITH AIRLINE



]}

1. Read route_5966 document from Couchbase

2. Parse JSON3. Pull out “airlineid” field4. Read airline_24 document from Couchbase

5. Parse JSON6. Pull out “callsign”7. Display airline name8. Throw away 2 objects


COMBINE ROUTE WITH AIRLINE



]}

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`


UNNEST

RETURN FLIGHTS FOR A PARTICULAR DAY

4. Foreach in “schedule”:a. Does it match requested day?

Y/Nb. Does it match requested day?

Y/Nc. Does it match requested day?

Y/Nd. Does it match requested day?

Y/Ne. Does it match requested day?

Y/Nf. Does it match requested day?

Y/Ng. 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 objectb. Handle errorsc. Manage memory

2. Parse JSON:a. Map transcoderb. Manage versioningc. Handle missing values

3. Read in “schedule” objecta. Instantiate objectb. Handle errorsc. Manage memory


RETURN FLIGHTS FOR A PARTICULAR DAY
