There are various ways you can perform database management. Using SQL and Python is one of the popular methods. SQL, a structured query language, can interact with the database where your data is stored. It is a standard programming language that developers use for relational DBMS. In this article at Hackernoon, Kalebu Jordan shares how to go about database management with SQL and Python.

Database Management Tips

Programmers use the following database management systems:

  • Hierarchical databases
  • Network databases
  • Relational databases
  • Object-oriented databases
  • Graph databases
  • ER model databases
  • Document databases
  • NoSQL databases

If you have worked on Oracle, Sybase, Microsoft SQL Server, Access, and Ingres, you know that SQL is the standard language for their management. You can update or collect information from the database with ease. The question is, how would you connect to the database management system using Python? Let’s find out below:

Path to Connect Database

  • Use CRUD operations for database management, i.e., ‘Create, Read, Update, and Delete’.
  • You would come across Python libraries like SQLite, PyMySQL, python-sql, and myql-connector. SQLite is common in these libraries.

Steps

  • The connect () method would link to an existing SQLite database or create a new one. Ensure that your database name has the .db extension. For instance, Customer.db can be an option.
  • Once connected, build a Cursor object and use its execute method for your SQL commands.
  • When you have new tables for database management, utilize the SQL Statements. The tables will have name and age as columns. Search up your database using DB Browser.
  • The process of inserting the data into the database is the same as creating those tables.
  • Open your database to check the values in each table.
  • Iterate the values in the Customer table.
  • You can easily change the Customer details in the table.
  • You can also add new columns to the table.

It is a brief guide to how you can use SQL and Python for database management. The guide is for beginners. However, developers also need to rehash their memories at times. So, the steps are useful for all levels of programmers.
