The size estimate of the result of a selection operation depends on the selection predicate We rst consider a single equality predicate, then a single comparison predicate, and nally combinations of predicates A = a (r): If we assume uniform distribution of values (that is, each value appears with equal probability), the selection result can be estimated to have nr /V (A, r) tuples, assuming that the value a appears in attribute A of some record of r The assumption that the value a in the selection appears in some record is generally true, and cost estimates often make it implicitly However, it is often not realistic to assume that each value appears with equal probability The branch-name attribute in the account relation is an example where the assumption is not valid There is one tuple in the account relation for each account It is reasonable to expect that the large branches have more accounts than smaller branches Therefore, certain branch-name values appear with greater probability than do others Despite the fact that the uniform-

As another example of an entity set that can be modeled as a weak entity set, consider offerings of a course at a university The same course may be offered in different semesters, and within a semester there may be several sections for the same course Thus we can create a weak entity set course-offering, existence dependent on course; different offerings of the same course are identi ed by a semester and a sectionnumber, which form a discriminator but not a primary key

Now that you understand how to cable up the appliances, let s talk about how failover works: how the appliances communicate with each other, how they discover problems, and when failover occurs

Although the basic E-R concepts can model most database features, some aspects of a database may be more aptly expressed by certain extensions to the basic E-R model In this section, we discuss the extended E-R features of specialization, generalization, higher- and lower-level entity sets, attribute inheritance, and aggregation

As I mentioned earlier in the Failover Cabling section, the failover link is either the serial cable used on the PIXs or an Ethernet cable with LBF The failover link is used to communicate the following information between the paired appliances: The state of the appliances: active or standby If the appliances are PIXs, their power status Failover hello messages Network link status of the appliances interfaces Exchange of MAC addresses used on the appliance interfaces Configuration of the active unit synchronized with the standby unit

An entity set may include subgroupings of entities that are distinct in some way from other entities in the set For instance, a subset of entities within an entity set may have attributes that are not shared by all the entities in the entity set The E-R model provides a means for representing these distinctive entity groupings Consider an entity set person, with attributes name, street, and city A person may be further classi ed as one of the following: customer employee Each of these person types is described by a set of attributes that includes all the attributes of entity set person plus possibly additional attributes For example, customer entities may be described further by the attribute customer-id, whereas employee entities may be described further by the attributes employee-id and salary The process of designating subgroupings within an entity set is called specialization The specialization of person allows us to distinguish among persons according to whether they are employees or customers As another example, suppose the bank wishes to divide accounts into two categories, checking account and savings account Savings accounts need a minimum balance, but the bank may set interest rates differently for different customers, offering better rates to favored customers Checking accounts have a xed interest rate, but offer an overdraft facility; the overdraft amount on a checking account must be recorded The bank could then create two specializations of account, namely savings-account and checking-account As we saw earlier, account entities are described by the attributes account-number and balance The entity set savings-account would have all the attributes of account and an additional attribute interest-rate The entity set checkingaccount would have all the attributes of account, and an additional attribute overdraftamount
