- Describe and give an example of the difference between synchronous and asynchronous data access.
- Answer
- Synchronous is automatic and requires that both ends are available at the same time, such as in order to talk to someone on the phone both people must be able to be on the phone call at the same time to interact; whereas asynchronous is delayed and does not require that both ends be available at the same time, such as in order to leave a voicemail message on someone's phone, the person receiving the message does not need to be available when the person is leaving the message.
- True or False. When an app retrieves data from TinyWebDB, it first requests the data and then it stops whatever it is doing and waits for the data to arrive. Explain.
- Answer
- False, it requests the data, but due to the asynchronous delay, the app will continue until without the retrieved data until it is retrieved, in our case 3 seconds.
- One aspect of abstraction is that it helps to reduce details to focus on what's relevant. How does the use of an external database in this app help reduce detail in the program?
- Answer
- Primarily it makes it simpler in that we don't have to set up a database in our own blocks.
