Library Management System - Python Project with Source Code

Work on one of the most popular python projects – Library Management System

A library management system keeps track of the books present in the library. It is an important piece of software which is a must at schools and colleges. We will build a library management system using Tkinter to make it interactive.

What is Tkinter?

Python offers various utilities to design the GUI wiz Graphical User Interface, and one such utility is Tkinter which is most commonly used. It is indeed one of the fastest and easiest ways to build GUI applications. Moreover, Tkinter is cross-platform, hence the same code works on macOS, Windows, and Linux.

Library Management System in Python

The library management system in python which we are going to build will look something like this

library management system python

Yes, this is the library management project which we are going to build. I know this may be a long article but be with me as at the end of the article you will be equipped with the knowledge to design and build great applications with decent UI.

Let’s begin!

How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.

In this article, we will be installing OpenJDK on Centos 8.

Best MySQL DigitalOcean Performance – ScaleGrid vs. DigitalOcean Managed Databases

HTML to Markdown

MySQL is the all-time number one open source database in the world, and a staple in RDBMS space. DigitalOcean is quickly building its reputation as the developers cloud by providing an affordable, flexible and easy to use cloud platform for developers to work with. MySQL on DigitalOcean is a natural fit, but what’s the best way to deploy your cloud database? In this post, we are going to compare the top two providers, DigitalOcean Managed Databases for MySQL vs. ScaleGrid MySQL hosting on DigitalOcean.

At a glance – TLDR
ScaleGrid Blog - At a glance overview - 1st pointCompare Throughput
ScaleGrid averages almost 40% higher throughput over DigitalOcean for MySQL, with up to 46% higher throughput in write-intensive workloads. Read now

ScaleGrid Blog - At a glance overview - 2nd pointCompare Latency
On average, ScaleGrid achieves almost 30% lower latency over DigitalOcean for the same deployment configurations. Read now

ScaleGrid Blog - At a glance overview - 3rd pointCompare Pricing
ScaleGrid provides 30% more storage on average vs. DigitalOcean for MySQL at the same affordable price. Read now

MySQL DigitalOcean Performance Benchmark
In this benchmark, we compare equivalent plan sizes between ScaleGrid MySQL on DigitalOcean and DigitalOcean Managed Databases for MySQL. We are going to use a common, popular plan size using the below configurations for this performance benchmark:

Comparison Overview
ScaleGridDigitalOceanInstance TypeMedium: 4 vCPUsMedium: 4 vCPUsMySQL Version8.0.208.0.20RAM8GB8GBSSD140GB115GBDeployment TypeStandaloneStandaloneRegionSF03SF03SupportIncludedBusiness-level support included with account sizes over $500/monthMonthly Price$120$120

As you can see above, ScaleGrid and DigitalOcean offer the same plan configurations across this plan size, apart from SSD where ScaleGrid provides over 20% more storage for the same price.

To ensure the most accurate results in our performance tests, we run the benchmark four times for each comparison to find the average performance across throughput and latency over read-intensive workloads, balanced workloads, and write-intensive workloads.

Throughput
In this benchmark, we measure MySQL throughput in terms of queries per second (QPS) to measure our query efficiency. To quickly summarize the results, we display read-intensive, write-intensive and balanced workload averages below for 150 threads for ScaleGrid vs. DigitalOcean MySQL:

Create a Music Player using Java [Source Code Included]

Java music player is a simple classic mp3 player which has features like playing selected mp3 music files, pausing the music, resuming the music, and stopping the music. The music player is used daily by all types of users. Music helps users to create a fresh mind, inspire life, and also boost the mind of the user.

Java Music Player Functionalities

  • Play the mp3 music.
  • Pause / resume the music.
  • Stop the music.

Project Prerequisites:

  • IDE Used: NetBeans 11.2 (You can use eclipse ide)
  • Java should be installed on the machine.
  • To build an mp3 music player using java we require basic knowledge of java.
  • Abstract Window Toolkit (AWT) & Swing packages are standard graphical user interfaces used to render graphics. By default, these packages are installed by java.
  • Jlayer library is required for performing music functions such as play, pause, resume, stop. Jlayer is an open-source library we need to download from the internet.
