What is a database in MIT App Inventor?
TinyWebDB is an App Inventor component that allows you to store data persistently in a database on the web. Because the data is stored on the web instead of a particular phone, TinyWebDB can be used to facilitate communication between phones and apps (e.g., multi-player games).
What are the components of MIT App Inventor?
There are two main types of components: visible and non-visible. Visible components such as Button, TextBox, Label, etc.
What is the difference between CloudDB and TinyDB?
Whereas TinyDB stores data only on the device running the app, a CloudDB is shared among users on multiple devices running the same app because it stores data online, in the cloud. Access to the web data is asynchronous, which means storing and retrieving data may not happen immediately.
What are the two types of MIT App Inventor?
In MIT App Inventor, users code application behavior using a block-based programming language. There are two types of blocks in App Inventor: built-in blocks and component blocks.
What is the difference between the TinyWebDB and TinyDB?
TinyDB is used to store data persistently on the phone (or whatever Android device on which the app is running). TinyWebDB, on the other hand, allows you to store data in a web database that can be shared amongst phones.
How many types of layout are available in MIT App Inventor?
The choices are: 1 = left aligned, 2 = right aligned, 3 = horizontally centered. Alignment has no effect if the HorizontalArrangement ‘s Width is Automatic . A number that encodes how the contents of the HorizontalArrangement are aligned vertically.
How many blocks are there in App Inventor?
Each of the three major component block types, i.e., events, methods, and properties, have corresponding “any component” blocks.
What is the use of MIT?

How are apps created with App Inventor stored in TinyDB?
Apps created with App Inventor are initialized each time they run. If an app sets the value of a variable and the user then quits the app, the value of that variable will not be remembered the next time the app is run. TinyDB is a persistent data store for the app, that is, the data stored there will be available each time the app is run.
