T1 T2 read(X) write(X) read(Z) write(Z) read(X) write(X) read(X) write(X) Commit Commit 1. State whether the aforementioned concurrent schedule is c-serializable 2. Determine the order of execution of operations when the strict two-phase locking a (2PL) is applied please how to do this kind of questions easily I need help?
In a highly concurrent application it could (theoretically) happen that data you've read in the first select is modified before the other selects are executed. If that is a situation that could occur in your application you should use a transaction to wrap your selects
If data is inconsistent there might be chance of money loss ..or data loss in simple terms while retrieving data using queries there might be some errors we get.to avoid all those the data must be in consistent state..

As per your transaction definition , Is select statement also a transaction since it will not change the content of DB.
In a highly concurrent application it could (theoretically) happen that data you've read in the first select is modified before the other selects are executed. If that is a situation that could occur in your application you should use a transaction to wrap your selects
Transaction management and transaction properties or same or different

If data is inconsistent there might be chance of money loss ..or data loss in simple terms while retrieving data using queries there might be some errors we get.to avoid all those the data must be in consistent state..
