It is a personal project. Each student should do it separately and submit one report for the
project.
You should submit a report before the deadline. The report submitted after the deadline will
be zero score.
DO NOT copy ANY words, figures and others from Internet and your classmates.
DBMS can help us to manage data conveniently, and also can improve the efficiency of data
retrieval greatly. Please compare data retrieval implemented by yourself using C/C++, Java or any
other language with DBMS to find the differences.
Suggested Steps:
Find some data for experiments. You can use all films with titles, directors, actors and other
related information. Some other data such as 'Infected cases by COVID-19', 'Stock data', 'Library
data' etc. is also fine. But the size should be reasonably large.
Store the data into a database table. Then use select in SQL to find the films with word "XXX" in
titles, and record the execution time.
Store the data into a file, and then load it into RAM. The data in RAM can be any format you
preferred. Design an algorithm to search "XXX" in titles. Record the execution time of your
algorithm.
Some other comparisons and experiments you would like to do. Such as you can reorganize data
into some other format for faster retrieval. You are recommended to study the mechanism of
DMBS for storing and retrieval
SUGGESTED structure of your report
1. Title
Please give your report a title that can reflect the core point of your work.
2. Introduction
To introduce what you want to prove in the experiments. DO NOT copy any text from Internet.
3. Experimental design
3.1 Experimental data and environments.
Introduce the data, DBMS and the programming language you choose. How you organize the
data.3.2 Experiments
Describe your experiments here. To make sure the experiments should be reasonable and the
comparisons should be fare.
3.3 Experimental results
Show your results in tables and figures, and analysis the differences of different methods.
4. Conclusions
Give your conclusions here. You can also present you options on DBMS.
Several website can give you some ideas to research, but those are only theory description:
1. Advantage of database management system over file system
2. Advantages of Database Management System
3. Characteristics and benefits of a database
......
Basic Requirement
1. Clearly and easy understanding design.
2. You need to show that you really do the experiments by some experimental details and
reasonable analysis.
Bonus
If you can do some of the following functions (but not limit to the following ones), you will win
bonus.
1. High concurrency and transaction management
2. User privileges management
3. Database index and file IO
4. Large data sets (the data is large enough and cannot be stored into RAM)
5. Compare performance of multiple databases with file system over different operation
systems
Submit
Submit a pdf file into sakai website before March. 29th.
