CBSE Class 12 Computer Science Project Work

The class project aims to create tangible and useful IT applications. Exploring the environment may help you identify a real-world problem.

For example, you can visit shops/business places, communities, or other organizations in their localities and inquire about how the organization functions and how data are generated, stored, and managed.

• You can take data stored in CSV or database files, analyze it using Python libraries, and generate appropriate charts to visualize it.
• You can use Python libraries to develop software for your school or any other social good.
• You should be sensitized to avoid plagiarism and violation of copyright issues while working on projects.
• Teachers should take the necessary measures for this. Any resources (data, images, etc.) used in the project must be suitably referenced.
• The project can be done individually or in groups of 2 to 3 students.
• The project should be started at least 6 months before the submission deadline.

CBSE Class 12 Computer Science Exam: Suggested Practical List

Data Handling

• Create a panda’s series from a dictionary of values and an array
• Given a Series, print all elements above the 75th percentile.
• Create a Data Frame for quarterly sales, where each row contains the item category, item name, and expenditure. Group the rows by category and print the total expenditure per category.
• Create a data frame for examination results and display row labels, column labels, data types of each column and the dimensions
• Filter out rows based on different criteria such as duplicate rows.
• Importing and exporting data between pandas and CSV files.

Visualization

• Given the school result data, analyse the students' performance on different parameters, e.g., subject-wise or class-wise.
• For the Data frames created above, analyze and plot appropriate charts with title and legend.
• Take data of your interest from an open source (e.g. data.gov.in), aggregate it, and summarize it. Then, plot it using different plotting functions of the Matplotlib library

Data Management

• Create a student table with the student ID, name, and marks as attributes where the student ID is the primary key.
• Insert the details of a new student in the above table.
• Delete the details of a student in the above table.
• Use the select command to get the details of the students with marks over 80.
• Find the minimum, maximum, sum, and average marks in a student marks table.
• Find the total number of customers from each country in the table (customer ID, customer Name, country) using group by.
• Write a SQL query to order the (student ID, marks) table in descending order of the marks.
