Python and DB2 App Development: Build a CRUD Application

Db2 is a family of data management products, including database servers, developed by IBM. They initially supported the relational model, but were extended to support object–relational features and non-relational structures like JSON and XML.

Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Its language constructs and object-oriented approach aim to help programmers write clear, logical code for small- and large-scale projects.

Python has a lot of GUI frameworks, but Tkinter is the only framework that’s built into the Python standard library. Tkinter has several strengths. It’s cross-platform, so the same code works on Windows, macOS, and Linux. Visual elements are rendered using native operating system elements, so applications built with Tkinter look like they belong on the platform where they’re run.

For python application to interact with a DB2 database it requires a database connector adaptor called ibm_db

Before you can run SQL statements to create, update, delete, or retrieve data, you must connect to a database. You can use the ibm_db API to connect to a database through either a cataloged or uncataloged connection. To improve performance, you can also create a persistent connection.

In this course we will a build a CRUD application from scratch using Python and IBM DB2 database.
