Exercises 11.List significant differrences between a file-processing system and a DBMS.2.What are the advantages and disadvantages of database?3.Explain the difference between physical and logical data independence.Discuss the ANSI-SPARC three-level architecture.4. What is a data model? Discuss the main types of data models.An integrated collection of concepts for describing and manipulating data, relationships between data, and constraints on the data in an organization. (See Section 2.3.)Object-based data models such as the Entity–Relationship model (see Section 2.3.1). Record-based data models such as the relational data model, network data model, and hierarchical data model (see Section 2.3.2). Physical data models describe how data is stored in the computer (see Section 2.3.3).Answer:•Physical data independence is the ability to modify the physical scheme without making itnecessary to rewrite application programs. Such modifications include changing from unblocked to blocked record storage, or from sequential to random access files.•Logical data independence is the ability to modify the conceptual scheme without making itnecessary to rewrite application programs. Such a modification might be adding a field to a record; an application pr ogram’s view hides this change from the program.Exercises 21.The following tables form part of a database held in a relational DBMS:Hotel (hotelNo, hotelName, city)Room (roomNo, hotelNo, type, price)Booking (hotelNo, guestNo, dateFrom, dateTo, roomNo)Guest (guestNo, guestName, guestAddress)where Hotel contains hotel details and hotelNo is the primary key;Room contains room details for each hotel and (roomNo, hotelNo) forms the primary key;Booking contains details of the bookings and (hotelNo, guestNo, dateFrom) forms the primary key;and Guest contains guest details and guestNo is the primary key.Identify the foreign keys in this schema. Explain how the entity and referential integrity rules apply to these relations.For each relation, the primary key must not contain any nulls.Room is related to Hotel through the attribute hotelNo. Therefore, the hotelNo in Room is FK,and should either be null or contain the number of an existing hotel in the Hotel relation. In this case study, it would probably be unacceptable to have a hotelNo in Room with a null value.Booking is related to Hotel through the attribute hotelNo. Therefore, the hotelNo in Booking is FK,and should either be null or contain the number of an existing hotel in the Hotel relation. However, because hotelNo is also part of the primary key, a null value for this attribute would be unacceptable.Similarly for guestNo. Booking is also related to Room through the attribute roomNo,(guestNo,roomNo) in booking is FK reference Room. guestNo in booking is FK reference Guest.Describe the relations that would be produced by the following relational algebra operations:(a)∏hotelNo (σprice> 50 (Room) )This will produce a relation with a single attribute (hotelNo) giving the number of those hotelswith a room price greater than £50.(b)σHotel.hotelNo=Room.hotelNo(Hotel⨯Room)This will produce a join of the Hotel and Room relations containing all the attributes of bothHotel and Room (there will be two copies of the hotelNo attribute). Essentially this willproduce a relation containing all rooms at all hotels.Produce some sample tables for these relations that observe the relational integrity rules. Suggest some enterprise constraints that would be appropriate for this schema.Student should provide some sample tables, observing entity and referential integrity. In particular, ensure the uniqueness for the composite primary keys of the Room and Booking tables.Some enterprise constraints may be:•There can be no two bookings for the same room in the same hotel on the same day.•For the Booking relation, dateFrom must be before dateTo.•Room price must be greater than 0 and less than £200.3.Consider the relational database of Figure 1,employee (person-name, street, city)works (person-name, company-name, salary)company (company-name, city)manages (person-name, manager-name)Figure 1. Relational databasewhere the primary keys are underlined.Give an expression in the relational algebra to express each of the following queries:a.Find the names of all employees who work for First Bank Corporation.b. Find the names, street address, and cities of residence of all employees whowork for First Bank Corporation and earn more than $10,000 per annum.c. Find the names of all employees in this database who live in the same cityas the company for which they work.Answer:a. Πperson-name (σcompany-name = “First Bank Corporation” (works))b. Πperson-name, street, city(σ(company-name = “First Bank Corporation” ∧salary > 10000)works ×employee)e. Πperson-name (employee ×works×company)。
