Explanation / Answer

TinyDatabase is a simple SQL similar like interface that specify the data.It also specify which data needed to be refreshed like additional information. It collects data from nodes, filters and combined them if any set of interested data is provided. TinyDB gives the opportunity to queries to execute some command when result is produced.

For example suppose for the university example from a query if a student produced id the instructor will produce the teacher id for respected department.

It also includes the ability to run those queries that project into flash memory in the sensor nodes. For creating table that reside in flash memory , running query that insert into those tables, retrieving from the table and also deleting table can be performed. But at a time only one query can be projected to the buffer, and whenever new query will arrive it will overwrite the data that was previously loaded in the log table. A query that is selected from a flash table and a query that has to write in the same table cannot be performed. The logging of a query needs to be stopped by DB client to gather data from flash tables.
