Chapter 12, Problem 1RQ
Explanation of Solution
Evolution from centralized
During the year 1970s, the centralized DBMS was implemented and the use of centralized DBMS stores the corporate data in single central site and providing the data access to dumb the terminals.
It worked well to fill the corporations structured information requirements, but it little drop at time of rapidly moving events needs quicker reply times and similarly rapid access to information.
At this time, the distributed database design is started with impact of internet. The success of internet and mobile technologies will increase use of the distributed database.
- The database management system supports the database distributed over the numerous different sites.
- Distributed DBMS manages the storage and processing of logically associated data across the connected systems wherein both “data” and “processing functions” are distributed between various sites.
In any case, distributed database are possible to identify the development of future database, mostly for particular mobile applications. This is specially needed because centralized database management is subject to such as high costs, reliability issues, scalability issues, performance degradation, and organization rigidity.

Write the KeanStudent class. The UML diagram of the class is represented below:
KeanStudent
- fullName: String
- keanID: int
-keanEmailAddress: String
cellPhoneNumber: String
+ numberOfStudent: int
+ KeanStudent()
+ KeanStudent(fullName: String, keanID: int, keanEmailAddress: String, cellPhoneNumber: String)
+getFullName(): String
+setFullName(newFullName: String): void
+getKeanIDO): int
+getKeanEmailAddress(): String
+getCellPhoneNumber(): String
+ setCellPhoneNumber(newCellPhoneNumber: String): void
+toString(): String
1. Implement the KeanStudent class strictly according to its UML one-to-one (do not include anything extra, do not miss any data
fields or methods)
2. Implement a StudentTest class to test the class KeanStudent you just created.
• Create two KeanStudent objects using a no-args constructor and one from the constructor with all fields.
o Print the contents of both objects.
。 Print numberOfStudent.
3. Add comments to your program (mark where data fields, constructors,…
MGMT SS STATS, an umbrella body that facilitates and serves various Social SecurityOrganizations/Departments within the Caribbean territories, stoodpoised to meet the needs of its stakeholders by launching an onlinedatabase at www.SSDCI.gov. The database will provide membersand the public access to the complete set of services that can (also)be initiated face-to-face, and it will provide managed, private, secure access to a repository ofpublic and/or personal information. Ideally, the database will have basic details of pensionplans recorded in the registry, member plan statistics, and cash inflows and outflows frompension funds.For example, insured persons accumulate contributions. Records for these persons will includeinformation on the insured persons able to acquire various benefits once work is interrupteddue to sickness, death, retirement, and maternity or employment injury. They will also includeinformation on pensions such as invalidity, disability, and survivors that stem from…

- (3e) Test-and-Set. The Test-and-Set instruction is used in hardware to achieve synchronization. It can be defined in the following way: function Test-and-Set (var target: boolean): boolean; begin Test-and-Set:= target; target := true; end; Now show how the Test-and-Set instruction can be used to protect a critical region and hence achieve mutual exclusion (do not worry about satisfying the bounded waiting condition).

But to roll and smoke a cigarette, the smoker needs three ingredients: tobacco, paper and matches. One of the smoker processes has paper, another has tobacco and the third has the matches. The agent has an infinite supply of all three materials. The agent places two of the ingredients on the table. The smoker who has the remaining ingredient then makes and smokes a cigarette, signaling the agent on completion. The agent then puts out another two of the three ingredients, and the cycle repeats. Given below is a solution to the Cigarette-Smokers Problem. Give initial conditions for the semaphores as well as plausible values for the variables i & j and r & s, such that the agent and smokers are synchronized.
