Assignment Information

Section 1: NoSQL (20 marks)

In this assignment, each student will select one NoSQL data store (Key-Value, Graph Databases, Column-based, Document Store, etc.) and a product that implements the selected technology:

1.  Write  a  research  report  on  the  NoSQL  data  store  and  product  (approx.  1000 words). Your report needs to discuss the NoSQL:

•    Data Model and its features

•   Justification for its development (e.g. advantages vs limitations - compared to relational model, application areas, etc.)

In the NoSQL product, you have chosen, discuss the

•   Storage architecture

•   Scalability (horizontal vs vertical scaling)

•   Query capabilities

•   Concurrency control features (ACID vs BASE)

•    Fault tolerance

and present a demo of basic CRUD operations on the selected product. (10 marks)

2.  Present  your  report  to  the  class  (duration:  5-7   minutes  presentation).  Your presentation  should  include  a  demo  of  the  technology  presented  in  use.  For example,a demo of CRUD operations of a NoSQL system showcasing its features. (8 marks)

3.  Contribute  a  summary  and  evaluation  of one  peer  student  presentation  on  a different technology from your presentation.  Include the following  in the  peer- evaluation:

a.  Name of student

b.  Topic of presentation

c.  Summary of technology presented and

d.  An  evaluation of the presentation – what was presented well, what was missed, how to improve etc.(2 marks)

Sample Topic Areas and Technologies:

•    Key-Value: DynamoDB, LevelDB, Riak, Oracle NoSQL, etc.

•   Column-based: BigTable, HBase, Amazon SimpleDB, Hypertable, etc.

•    Document Store: MongoDB, CouchDB, etc.

•   Graph Databases: Neo4J, DEX, GraphBase, GraphChi, etc.

Section 2: Map-Reduce Exercise (Optional – 2 bonus marks)

In this exercise you write a MapReduce job in Java that reads any text input and computes the average length of all words that start with each character.

For any text input, the job should report the average length of words that begin with ‘a’, ‘b’, and so forth.

For example, for input:

Now is not the time

The output would be:

N            3.0

i            2.0

n            3.0

t            3.5

Submission

1.  The Research Report is to be submitted via Canvas - Assignment 3 Written Report. 2.  The report needs to be presented in class in Week 12 lecture or tutorial sessions.

3.  Peer-evaluation  of  student  presentation  submitted  via  Assignment  3  –  Peer Evaluation Canvas Discussion.

4.  The  Map  Reduce  exercise  is  to  be  submitted  via  Canvas  –  Assignment  3 MapReduce  Exercise  (zipped  file  containing  all  Java  files)  and  demonstrated during tutorial sessions (optional).
