Chapter 14, Problem 5RQ
Explanation of Solution
Stream Processing:
Stream processing is a technology that lets users query continuous data stream and detect conditions within small time period after receiving the data.
- The decision is made to know which data should be stored and which should be discarded.
- In some situations, large volumes of data enter the system, but it is not feasible to store all of the data.
- So as soon as the data enters the system, it should be processed and filtered to detect which data to keep and which data to discard.
Needs of Stream Processing:
- The main reason why the stream processing is needed is because it is a technology that is capable of providing insights faster, often within milliseconds to seconds...

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…

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).

- Consider a system with three smoker processes and one agent process. Each smoker continuously rolls a cigarette and then smokes it. 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. Write a couple of sentences on why these initial conditions are necessary and sufficient. Solution: var a: array [0..2] of semaphore (initial condition =…arrow_forwardLevel-0 Diagram for this: A customer sends in an order form containing details of their order and their membership number. A check is made to verify that they are a member. When their order is verified, a check is made to validate that the items ordered are produced by the company. Next, the valid order is used to update the daily order file, and then used to create a shipping list and invoice, which are sent on to the Order Fulfilment System.arrow_forwardIn this assignment, you will use all of the graphics commands you have learned to create an animated scene. Your program should have a clear theme and tell a story. You may pick any school-appropriate theme that you like.

However, the grader will only perform basic checks against some requirements. If your code passes, you should submit your work, and your teacher will manually grade your submitted work using a rubric.arrow_forward
