5. Data is Shared Departures data is public, passengers need to see this information. The departures data may be available on the internet. Data on tickets is not public but it is shared, check in desk, boarding gate, flight crew. Lecture 5: Review5

6. Database A database can be shared. One server holds the data and serves it to many clients. As the data is stored in one place only there can be only one version of the data. Any updates are available to all clients immediately. Lecture 6: Airport Departures6

15. Summary You will build the application on your own. I will show you examples using a different database. You can apply the examples to the Flights database. I will check your work on Thursday. You will need to explain, in English, what your program does. Lecture 5: Review15
