Project Work for Class XII Informatics Practices (065) - CBSE 2020-2021

  Marks  allotted : 05 Marks A. PROJECT GUIDELINES The aim of the class project is to create tangible and useful IT application. The learner may identify a real-world problem by exploring the environment. e.g. Students can visit shops/business places, communities or other organizations in their localities and enquire about functioning of the organization, and how data are generated, stored, and managed. The learner can take data stored in csv or database file and analyze using Python libraries and generate appropriate charts to visualize. If an organization is maintaining data offline, then the learner should create a database using MySQL and store the data in tables. Data can be imported in Pandas for analysis and visualization. Learners can use Python libraries of their choice to develop software for their school or any other social good. Learners should avoid plagiarism and violation of copyright issues while working on projects. Any resources (data, image etc.) used in t...
