The primary key of an entity set allows us to distinguish among the various entities of the set We need a similar mechanism to distinguish among the various relationships of a relationship set Let R be a relationship set involving entity sets E1 , E2 , , En Let primary-key(Ei ) denote the set of attributes that forms the primary key for entity set Ei Assume for now that the attribute names of all primary keys are unique, and each entity set participates only once in the relationship The composition of the primary key for a relationship set depends on the set of attributes associated with the relationship set R If the relationship set R has no attributes associated with it, then the set of attributes primary-key(E1 ) primary-key(E2 ) primary-key(En ) describes an individual relationship in set R If the relationship set R has attributes a1 , a2 , , am associated with it, then the set of attributes primary-key(E1 ) primary-key(E2 ) primary-key(En ) {a1 , a2 , , am } describes an individual relationship in set R In both of the above cases, the set of attributes primary-key(E1 ) primary-key(E2 ) primary-key(En ) forms a superkey for the relationship set In case the attribute names of primary keys are not unique across entity sets, the attributes are renamed to distinguish them; the name of the entity set combined with the name of the attribute would form a unique name In case an entity set participates more than once in a relationship set (as in the works-for relationship in Section 212), the role name is used instead of the name of the entity set, to form a unique attribute name pdf417 java api The pdf417 decode Open Source Project on Open Hub

The structure of the primary key for the relationship set depends on the mapping cardinality of the relationship set As an illustration, consider the entity sets customer and account, and the relationship set depositor, with attribute access-date, in Section 212 Suppose that the relationship set is many to many Then the primary key of depositor consists of the union of the primary keys of customer and account However, if a customer can have only one account that is, if the depositor relationship is many to one from customer to account then the primary key of depositor is simply the primary key of customer Similarly, if the relationship is many to one from account to customer that is, each account is owned by at most one customer then the primary key of depositor is simply the primary key of account For one-to-one relationships either primary key can be used For nonbinary relationships, if no cardinality constraints are present then the superkey formed as described earlier in this section is the only candidate key, and it is chosen as the primary key The choice of the primary key is more complicated if cardinality constraints are present Since we have not discussed how to specify cardinality constraints on nonbinary relations, we do not discuss this issue further in this chapter We consider the issue in more detail in Section 73 pdf417 java api zxing/PDF417Reader. java at master · zxing/zxing · GitHub

R1 = 4 The notions of an entity set and a relationship set are not precise, and it is possible to de ne a set of entities and the relationships among them in a number of different ways In this section, we examine basic issues in the design of an E-R database schema Section 274 covers the design process in further detail Consider the entity set employee with attributes employee-name and telephone-number It can easily be argued that a telephone is an entity in its own right with attributes telephone-number and location (the of ce where the telephone is located) If we take this point of view, we must rede ne the employee entity set as: The employee entity set with attribute employee-name The telephone entity set with attributes telephone-number and location The relationship set emp-telephone, which denotes the association between employees and the telephones that they have What, then, is the main difference between these two de nitions of an employee Treating a telephone as an attribute telephone-number implies that employees have precisely one telephone number each Treating a telephone as an entity telephone permits employees to have several telephone numbers (including zero) associated with them However, we could instead easily de ne telephone-number as a multivalued attribute to allow multiple telephones per employee The main difference then is that treating a telephone as an entity better models a situation where one may want to keep extra information about a telephone, such as FIGURE 13-10 javascript parse pdf417 PeculiarVentures/js-zxing-pdf417: Javascript port of the ... - GitHub
