Visual Basic .NETの基礎から販売管理システム構築まで。SQLの使い方も含まれています。

Dive into Visual Basic .NET development with this comprehensive course! We'll start with the fundamentals, beginning with Visual Basic .NET installation and creating your first menu program. You'll then build a solid foundation in programming concepts like variables, conditional statements, and loops through practical examples.

Next, master SQL database installation and learn the essential SQL basics. This includes creating, viewing, adding, deleting, and updating tables. You'll gain hands-on experience manipulating tables within Visual Basic .NET, exploring both the user-friendly Visual Basic .NET Navigator and developing custom programs for granular table control.

Learn how to integrate tables with common Visual Basic .NET controls like text boxes, combo boxes, list boxes, checkboxes, and radio buttons through detailed examples.

The core of this course focuses on building a sales management system. You'll delve into practical SQL applications using tables like customer, product, sales invoice header, and sales invoice detail. We'll cover essential SQL techniques including joins, aggregations, and updates to manage your sales data effectively.

Develop key components of your sales management system through practical programming exercises. This includes creating programs for:

• Master Data Management: Registering, searching, and managing customer (including categorization), and product data. You'll also learn to update and delete master data.
• Sales Invoice Program: This is a key component, and we'll leverage the previously created customer and product search programs as building blocks. The program will cover adding new invoices, searching existing ones, updating invoice details, and deleting invoices. We separate these operations for data integrity, but the course outlines how to combine them into a single program.
• Payment Voucher Program: Similar to master data management, this program follows a similar workflow, adding new payment vouchers as individual records.
• Reporting & Inquiry Programs: We'll use SQL commands to generate data for reports and inquiries, displaying and printing the results. We'll also introduce Grapecity, a commercial tool, for advanced reporting and printing capabilities.

This course provides a practical, step-by-step approach to building a functional Visual Basic .NET sales management system, equipping you with valuable skills in both front-end development and database management.
