Question:

An application consists of three transactions T1, T2, and T3 that are defined below:

TI: begin transaction

read(x); read(z); write(x-5); write(z+5);

end transaction

T2: begin transaction

Read(z); write(z-8); read(y); write(y +8);

end transaction

I3: begin transaction

read(x); write(x+4); read(y); write(y-4);

end transaction

Describe how the concurrency of these three transactions can be controlled by using the following:

Same type of locks for both read and write operations
Type-specific locks
Intention-to-write locks
Optimistic concurrency control scheme
Timestamp-based concurrency control scheme
