To understand how the presence of delete instructions affects concurrency control, we must decide when a delete instruction con icts with another instruction Let Ii and Ij be instructions of Ti and Tj , respectively, that appear in schedule S in consecutive order Let Ii = delete(Q) We consider several instructions Ij Ij = read(Q) Ii and Ij con ict If Ii comes before Ij , Tj will have a logical error If Ij comes before Ii , Tj can execute the read operation successfully Ij = write(Q) Ii and Ij con ict If Ii comes before Ij , Tj will have a logical error If Ij comes before Ii , Tj can execute the write operation successfully Ij = delete(Q) Ii and Ij con ict If Ii comes before Ij , Ti will have a logical error If Ij comes before Ii , Ti will have a logical error Ij = insert(Q) Ii and Ij con ict Suppose that data item Q did not exist prior to the execution of Ii and Ij Then, if Ii comes before Ij , a logical error results for Ti If Ij comes before Ii , then no logical error results Likewise, if Q existed

Each type of signal has its own speed and distance limitations The data rate of a signal generally determines the distance it is able to travel The slower the data rate, the longer the distance The rate of a signal is typically measured in baud, representing the number of times per second that the state of a communication line (signal) changes The higher the baud, the faster the data rate Table 4-7 lists the maximum distances achievable, assuming the corresponding data rate (baud) for an EIA/TIA-232 signal Table 4-8 lists the maximum distances achievable for EIA/TIA-449, V35, X21, and EIA-530 signals Table 4-7: Speed and Distance Limits for EIA/TIA-232 Signals

prior to the execution of Ii and Ij , then a logical error results if Ij comes before Ii , but not otherwise We can conclude the following: Under the two-phase locking protocol, an exclusive lock is required on a data item before that item can be deleted Under the timestamp-ordering protocol, a test similar to that for a write must be performed Suppose that transaction Ti issues delete(Q) If TS(Ti ) < R-timestamp(Q), then the value of Q that Ti was to delete has already been read by a transaction Tj with TS(Tj ) > TS(Ti ) Hence, the delete operation is rejected, and Ti is rolled back If TS(Ti ) < W-timestamp(Q), then a transaction Tj with TS(Tj ) > TS(Ti ) has written Q Hence, this delete operation is rejected, and Ti is rolled back Otherwise, the delete is executed

A g o o d database design ensures that users can change the contents o f a database without unexpected side effects For example, with a university database, a user should be able to insert a n e w course without having to simultaneously insert a n e w offering o f the course and a new student enrolled in the course Likewise, when a student is deleted from the database due to graduation, course data should not be inadvertently lost These problems

We have already seen that an insert(Q) operation con icts with a delete(Q) operation Similarly, insert(Q) con icts with a read(Q) operation or a write(Q) operation; no read or write can be performed on a data item before it exists Since an insert(Q) assigns a value to data item Q, an insert is treated similarly to a write for concurrency-control purposes: Under the two-phase locking protocol, if Ti performs an insert(Q) operation, Ti is given an exclusive lock on the newly created data item Q Under the timestamp-ordering protocol, if Ti performs an insert(Q) operation, the values R-timestamp(Q) and W-timestamp(Q) are set to TS(Ti )

Consider transaction T29 that executes the following SQL query on the bank database: select sum(balance) from account where branch-name = Perryridge Transaction T29 requires access to all tuples of the account relation pertaining to the Perryridge branch Let T30 be a transaction that executes the following SQL insertion: insert into account values (A-201, Perryridge , 900) Let S be a schedule involving T29 and T30 We expect there to be potential for a con ict for the following reasons:
