GetData is not working. Why is this? The purpose of the DataService class is to simplify database operations in an application. It allows for creating, reading, updating, and deleting data (CRUD operations). The class hides the details of database management, so developers don’t have to write SQL queries directly. It provides error handling to ensure that database operations are performed safely and reliably. The unified interface aids in the maintainability and extensibility of the application. Overall, the DataService class makes data management more efficient and structured in applications.
