Human Resources Skills Application
The Human Resources Skills application is a sample application built on the ADO.NET Entity Framework. The application manages information about employee skills. The Visual Studio solution provided for this sample contains projects for both a Windows application and an ASP.NET application. The ASP.NET application uses the EntityDataSource control for data binding.
This sample is available on the Entity Framework Documentation Samples site on MSDN Code Gallery.
A human resources department may need to manage information about employee skills. The Human Resources Skills application helps users find information about the skills of employees or find employees with various skills.
The application specifies employee skills by using entities, and it relates the skills to employees using associations. Skills entities define properties for skill name and description. Another entity contains supplemental information about skills by including the URL for detailed information. An association connects the supplemental information with the skill it describes. References representing people who have worked with employees are also implemented as entities. The references are accessed through an association between employee entities and reference entities.
