7 Normalization of Relational Tables 223 Another important consideration in asserting functional dependencies is the minimal i s m o f the L H S It is important to distinguish w h e n one column alone is the determinant versus a combination o f columns A n F D in which the LHS contains more than one column usually represents an M - N relationship For example, the statement, "The order quantity is collected for each product purchased in an order" translates to the F D OrdNo, ProdNo > OrdQty Order quantity depends o n the combination o f order number and product number, not just one o f these columns minimal determinant Part o f the confusion about the minimalism o f the LHS is due to the meaning o f columns in the left-hand versus right-hand side o f a dependency To record that student Social Security number determines city and class, y o u can write either StdSSN > StdCity, StdClass (more compact) or StdSSN > StdCity and StdSSN > StdClass (less compact) If you assume that the e-mail address is also unique for each student, then y o u can write

Summary

Special concurrency-control techniques can be developed for special data structures Often, special techniques are applied in B+ -trees to allow greater concurrency These techniques allow nonserializable access to the B+ -tree, but they ensure that the B+ -tree structure is correct, and ensure that accesses to the database itself are serializable

the determinant (col umn^) appearing on the LHS of a functional de pendency) must not contain extra columns This minimalism re quirement is similar to the minimalism require ment for candidate keys

Figure 4-11: Rollover cable vs straight-through cable You can tell the difference between a rollover cable and a straight-through cable by comparing the two plugs on the ends of the cable If you hold the two plugs side by side and the first wire on the first plug is the same color (typically white) as the last wire on the second plug, that cable is probably a rollover cable A rollover cable connects pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5 Each wire is responsible for carrying a particular signal, based on the type of adapter used (this is discussed in the upcoming sections) There are two groups of signals: signals that are sent and signals that are received, as defined in Table 4-12 Table 4-12: Signals and Functions

cause these F D s imply that the combination o f StdSSN and Email is the determinant Thus, y o u should write F D s so that the LHS does not contain unneeded c o l u m n s The prohibition against unneeded columns for determinants is the same as the prohibition against unneeded columns in candidate keys Both determinants and candidate keys must be minimal

161 Show that the two-phase locking protocol ensures con ict serializability, and that transactions can be serialized according to their lock points 162 Consider the following two transactions: T31 : read(A); read(B); if A = 0 then B := B + 1; write(B) T32 : read(B); read(A); if B = 0 then A := A + 1; write(A) Add lock and unlock instructions to transactions T31 and T32 , so that they observe the two-phase locking protocol Can the execution of these transactions result in a deadlock 163 What bene t does strict two-phase locking provide What disadvantages result 164 What bene t does rigorous two-phase locking provide How does it compare with other forms of two-phase locking 165 Most implementations of database systems use strict two-phase locking Suggest three reasons for the popularity of this protocol 166 Consider a database organized in the form of a rooted tree Suppose that we insert a dummy vertex between each pair of vertices Show that, if we follow the tree protocol on the new tree, we get better concurrency than if we follow the tree protocol on the original tree
