Have you ever looked at lines of code and wondered, "How on earth do people understand this?" Or maybe you've tried learning Java before and gave up because it felt too complicated? What if I told you that mastering Java doesn't have to be intimidating, boring, or confusing? What if you could go from absolute beginner to confident programmer step-by-step, without feeling lost along the way? In Java Mastery: The Complete Guide to Modern Programming for Beginners by Paul Reigns, you'll discover that Java is not just a programming language - it's your gateway to building apps, games, websites, and even enterprise-level software. But here's the real question... are you ready to unlock that power? Think about it: Have you been searching for a clear, beginner-friendly roadmap to Java programming? Do you wish you could understand coding concepts without getting stuck in complicated jargon? Are you ready to turn your ideas into real-world projects that actually work? This book doesn't just dump code on you - it walks you through the why behind every step. You'll learn how to write your first program, understand core Java fundamentals, work with data, master object-oriented programming, handle errors like a pro, and even explore advanced topics like multithreading, databases, and web development. By the end, you won't just "know" Java - you'll be able to think like a programmer. So, I'll ask you again: Do you want to finally feel confident in your ability to code? Do you want a skill that can open doors to tech jobs, freelancing, and personal projects? Do you want to stop "wanting to learn programming" and start actually doing it? If your answer is "YES" to any of these questions, then this book is for you. Your journey to Java mastery starts here. Every chapter builds on the last, making sure you're never overwhelmed but always challenged to grow. Whether you dream of creating apps, building a career in tech, or simply understanding the technology shaping our world - this is your starting point. Stop wondering. Start coding.

ZERO TO MASTERY: THE COMPLETE GUIDE TO LEARNING MYSQL BASED MULTIFORM PYTHON GUI
In this project, we provide you with the MySQL version of The Oracle Database Sample Schemas that provides a common platform for examples in each release of the Oracle Database. The sample database is also a good database for practicing with SQL, especially MySQL. The detailed description of the database can be found on: http://luna-ext.di.fc.ul.pt/oracle11g/server.112/e10831/diagrams.htm#insertedID0. The four schemas are a set of interlinked schemas. This set of schemas provides a layered approach to complexity: A simple schema Human Resources (HR) is useful for introducing basic topics. An extension to this schema supports Oracle Internet Directory demos; A second schema, Order Entry (OE), is useful for dealing with matters of intermediate complexity. Many data types are available in this schema, including non-scalar data types; The Online Catalog (OC) subschema is a collection of object-relational database objects built inside the OE schema; The Product Media (PM) schema is dedicated to multimedia data types; The Sales History (SH) schema is designed to allow for demos with large amounts of data. An extension to this schema provides support for advanced analytic processing. The HR schema consists of seven tables: regions, countries, locations, departments, employees, jobs, and job_histories. This book only implements HR schema, since the other schemas will be implemented in the next books.
ZERO TO MASTERY: THE COMPLETE GUIDE TO LEARNING SQL SERVER AND DATA SCIENCE WITH PYTHON GUI
In this project, we provide you with a SQL SERVER version of an Oracle sample database named OT which is based on a global fictitious company that sells computer hardware including storage, motherboard, RAM, video card, and CPU. The company maintains the product information such as name, description standard cost, list price, and product line. It also tracks the inventory information for all products including warehouses where products are available. Because the company operates globally, it has warehouses in various locations around the world. The company records all customer information including name, address, and website. Each customer has at least one contact person with detailed information including name, email, and phone. The company also places a credit limit on each customer to limit the amount that customer can owe. Whenever a customer issues a purchase order, a sales order is created in the database with the pending status. When the company ships the order, the order status becomes shipped. In case the customer cancels an order, the order status becomes canceled. In addition to the sales information, the employee data is recorded with some basic information such as name, email, phone, job title, manager, and hire date. In this project, you will write Python script to create every table and insert rows of data into each of them. You will develop GUI with PyQt5 to each table in the database. You will also create GUI to plot: case distribution of order date by year, quarter, month, week, and day; the distribution of amount by year, quarter, month, week, day, and hour; the distribution of bottom 10 sales by product, top 10 sales by product, bottom 10 sales by customer, top 10 sales by customer, bottom 10 sales by category, top 10 sales by category, bottom 10 sales by status, top 10 sales by status, bottom 10 sales by customer city, top 10 sales by customer city, bottom 10 sales by customer state, top 10 sales by customer state, average amount by month with mean and EWM, average amount by every month, amount feature over June 2016, amount feature over 2017, and amount payment in all years.
