Detailed Specification

You are expected to work individually and complete a report that addresses the following tasks. You need to cite all sources you  rely on with in-text style. You may include material discussed in the lectures or labs, but additional credit will be given for independent research. Note: References should be in Harvard format. The word count does NOT include references.

 

 

 

·       Part A (25 Marks)

 

• Task A.1 [mark 10] Explain the main characteristics of Big Data. (Word count: 200 words ±10%)

 

• Task A.2 [mark 15] Compare Hadoop and Relational Database Systems. Give an application scenario that is well suited to Hadoop and explain your reason. (Word count: 300 words ±10%)

 

 

 

·       Part B (30 Marks):   MapReduce Programming

 

Suppose that you have a large student file which cannot be stored in a single machine. Each record of this file contains information: (Student_ID, Student_Name, Sex, Age, Module, Grade, Department).

 

• Task B.1 [mark 15] Please design a MapReduce Algorithm (Pseudo-codes or Java Codes) to output the average grade for each module. The algorithm is expected to be as efficient as possible.

 

• Task B.2 [mark 15] Describe the algorithm designed. You should explain how the input is mapped into (key, value) pairs by the map stage, i.e., specify what is the key and what is the associated value in each pair, and, if needed, how the key(s) and value(s) are computed. Then you should explain how the output (key, value) pairs of the map stage are processed by the reduce stage to

 

get  the  final  answer(s).     You should also analyse the efficiency of the MapReduce algorithm designed. (Word count: 300 words ±10%)

 

• Part C (45 marks): Big Data Project Analysis

The CropY company is a leading provider of precision agriculture service. Precision agriculture is the science of gathering, processing, and analysing temporal, spatial and individual data. It combines other information to support management decisions according to estimated variability for improved resource use efficiency, productivity, quality, profitability.

 

The CropY company is now plan to develop a big data project to meet the following requirements: help worldwide users better understanding the implications of the weather and making contingency plans; buying supplies, such as fertilizer and seeds; as well as maintaining and monitoring the quality of yield, whether livestock or crops; knowing the variety of cultivated plants, conditions of its growth and its needs of seeds; choosing the type of fertilizer and pesticides, understanding their employment conditions and their impact on the climate- soil-plant; recognizing daily water needs for each kind of plant; calculating the median and mean values of yield; studying the conditions of natural environment; estimating the financial revenue and manage the potential risks.

 

• Task C.1 [mark 10]: The volume of big data is expected to be more than 500 Petabytes. The data will come from various sensors, satellites, drones, social media, market data, Online news feed etc. The Figure 1 below shows some example data of CropY Some IT technician plan to build a data warehouse to store data for further data analysis tasks but some others believe data lake is a better choice. Which choice do you prefer? Please justify your choice. (Word count: 300 words ±10%)

 

 

Figure 1. Example Data of CropY Company

 

 

• Task C.2 [mark 10]: The data of CropY company includes a large collection of plants, corps, diseases, symptoms, pests, and relationships between them. The CropY company needs to build a data analytical store which can facilitate queries like: “find all diseases which are directly or indirectly caused by nitrogen

deficiency”. Please recommend a data store and justify your choice. (Word

count: 300 words ±10%)

 

• Task C.3 [mark 15]: Some prediction and analytics services provided by the  CropY company require to response in a few seconds after the arrival of new data. Namely, they are real time or near real time prediction and analytics tasks. Some IT managers suggested a popular distributed processing framework — MapReduce to implement these tasks. Do you agree with that? Please justify your choice. (Word count: 300 words ±10%)

 

• Task C.4 [mark 10]: CropY company decided to move most of applications and services to cloud. These applications and services need to be highly available, scalable, and accessible from worldwide. Note that some data such as price and customer data are confidential. Please design a cloud hosting strategy for this big data project and explain how your design will meet the security, scalability, high availability. (Word count: 300 words ±10%)
