Unit III: Database Management

  • Database concepts: introduction to database concepts and its need
  • Relational data model: relationship, attribute, tuple, domain, degree, cardinality, keys (candidate key, primary key, alternate key, foreign key)
  • Structured query language: introduction, data definition language and data manipulation language, data type (char(n), varchar(n), int, float, date), constraints (not null, unique, primary key) , create database, use database, view databases, drop database, view tables, create table, describe table, modify table (add and remove attribute, add and remove primary key), delete table, insert, delete, select, operators (mathematical, relational and logical), aliasing, distinct clause, where clause, in, between, order by, meaning of null, is null, is not null, like, update command, delete command, aggregation functions (max, min, avg, sum, count), group by , having clause, joins: Cartesian product on two tables, equi-join and natural join
  • Python interface with an SQL database: connecting SQL to Python, performing insert, update and delete queries using the cursor, displaying data using fetchone(), fetchall (), rowcount, creating database connectivity applications

5. Practice

6. Suggested Practice List:

Python Programming

  • Read a text file line by line and display each word separated by a #.
  • Read a text file and display the number of vowels/consonants/uppercase/lowercase letters in the file.
  • Delete all lines containing the ‘a’ character in one file and write it to another file.
  • Create a binary file with name and serial number. Search for a given personnel number and display the name, if not found, display the appropriate message.
  • Create a binary file with roll number, name and marks. Enter a personnel number and update the markers.
  • Write a random number generator that generates random numbers between 1 and 6 (simulates a dice).
  • Write a Python program to implement a stack using list.
  • Create a CSV file by entering user ID and password, read and find the password for the given user ID.

Data base management

  • Create a student table and insert data. Implement the following SQL commands on the student table: o ALTER table to add new attributes / modify data type / delete attribute o UPDATE table to modify data o ORDER By to display data in ascending / descending order o DELETE to delete the tuple(s) o GROUP BY and find the min, max, sum, count and average
  • A similar exercise can be framed for other cases.
  • Integrate SQL with Python by importing the appropriate module.

8. Project

The goal of the class project is to create something tangible and useful using Python file management/Python-SQL connectivity. This should be done in groups of two to three students and should be started by the students at least 6 months before the submission deadline. The goal here is to find a real-world problem worth solving.

Students are encouraged to visit local businesses and interview them about the issues they face. For example, if a business is having trouble creating invoices for filing GST claims, students can complete a project that takes the raw data (list of transactions), groups transactions by category, accounts for tax rates of GST and creates invoices in the correct format. Students can be extremely creative here. They can use a wide variety of Python libraries to create user-friendly applications such as games, software for their school, software for their disabled peers, and mobile applications. Of course, to complete some of these projects, additional learning is required. this should be encouraged. Students must be able to teach themselves.

Students should be sensitized to avoid plagiarism and copyright violations when working on projects. Teachers must take the necessary measures for this purpose.
