About Project	Project Details	Definition
Project Name	Django Note Taking App	The Django Note Taking App is developed using Python Django, HTML,CSS and JavaScript, This Django Notes A simple web application created with Django, a Python-based web framework, for taking notes.

Django is a web framework built by experienced developers that takes care of a lot of the heavy lifting so you can focus on developing your app instead of reinventing the wheel.
Developer Name	itsourcecode.com	Free projects containing source code in Java, PHP, Python, Django, VB.Net, Visual Basic, C, C++, C#, Javascript, and other languages are available on this website.
IDE Tool (Recommended)	Sublime, Visual Studio, PyCharm	Sublime Text is a source code editor that is available for purchase. It comes with built-in support for a variety of programming and markup languages. Plugins, which are often community-built and maintained under free-software licenses, allow users to extend the functionality of the system. Sublime Text has a Python API to help with plugins.
Project Type	Web Application	A web application, unlike computer-based software programs that operate locally on the device’s operating system, is application software that runs on a web server. The user uses a web browser with an active network connection to access web apps.
Database	SQLite	SQLite is a programming language that is used to create embedded software for devices such as televisions, cell phones, and cameras. It can handle HTTP requests with low to medium traffic. SQLite has the ability to compress files into smaller bundles with less metadata. SQLite is a temporary dataset that is used within an application to process data.
