Backendless can create tables when you store object hierarchies from a client application. Also, we described how to manually create data tables using Backendless Console.
In another post, we described a feature where you can import data to Backendless using CSV files. In that post, we used CSV files that already had the data type defined for each column.
In Java, entity objects are classes that represent data from your table. From an object-oriented perspective, these objects are built to encapsulate your data in the real-world problem domain.
