In Section 2.8.2, we apply the two initial database-design phases to our banking- enterprise example. She can also examine the design to remove any redundant features. software tech. The bank maintains a record of each account’s balance, and the most recent date on which the account was accessed by each customer holding the account. • Whether using aggregation (Section 2.7.5) is appropriate; aggregation groups a part of an E-R diagram into a single entity set, allowing us to treat the aggregate entity set as a single unit without concern for the details of its internal structure. The bank also keeps track of the employee’s start date and, thus, length of employment. The interaction between user and bank has been substantially improved by deploying ATMs, phone banking, Internet banking, and more recently, mobile banking. The Enterprise Surveys implemented in European and Central Asian countries are also known as Business Environment and Enterprise Performance Surveys (BEEPS) and are jointly conducted by the World Bank Group, the European Bank for Reconstruction and Development (EBRD), the European Investment Bank (EIB), and the European Commission (EC).

The initial phase of database design, then, is to characterize fully the data needs of the prospective database users. The collection of data, usually referred to as the database, contains information relevant to an enterprise. In a specification of functional requirements, users describe the kinds of operations (or transactions) that will be performed on the data. A fully developed conceptual schema will also indicate the functional requirements of the enterprise. Enterprise Surveys offers an expansive array of economic data on 164,000 firms in 144 countries. In this section, we consider how a database designer may select from the wide range of alternatives. 26. Drawing on the discussions in Section 2.8.2.3, we now present the completed E-R diagram for our example banking enterprise. • works-for, a relationship set between employee entities with role indicators man- ager and worker; the mapping cardinalities express that an employee works for only one manager and that a manager supervises one or more employees. • The customer entity set, with attributes customer-id, customer-name, customer- street; and customer-city. The Bank Account Management System is an application for maintaining a person's account in a bank. • loan-branch, a many-to-one relationship set that indicates in which branch a loan originated. The description that arises from this design phase serves as the basis for specifying the conceptual structure of the database. Additional descriptive features are the multivalued attribute dependent-name, the base attribute start-date, and the derived at- tribute employment-length.

Attributes The E-R Model: Introduction 語意 Unit 6 Database Design … Details of Banking Enterprise Database The major characteristics of the banking enterprise are explained by the following schema and the brief description of each table: The bank is organized into branches. We have presented a brief overview of the database-design process to provide a context for the discussion of the E-R data model. Each BRANCH is located in a particular city and is identified by a unique name. From the characteristics listed in Section 2.8.2.1, we begin to identify entity sets and their attributes: • The branch entity set, with attributes branch-name, branch-city, and assets. E.g. Figure 2.22 depicts the full representation of a conceptual model of a bank, expressed in terms of E-R concepts.
