Building Line-of-Business (LOB) applications, commonly known as "Forms over Data" apps, involves creating user interfaces that allow users to interact with underlying data sources through structured forms. These applications are essential for managing business processes, enabling data entry, validation, and retrieval in a streamlined manner. LOB apps typically focus on CRUD operations (Create, Read, Update, Delete) and are designed to meet specific organizational needs, from customer relationship management to inventory tracking. The goal is to provide intuitive, efficient interfaces that empower users to work with data without requiring technical expertise, while ensuring data integrity and business logic enforcement.
