Development Efficiency

Application programming interfaces (APIs) and resource dispensers make applications scalable and robust. Resource dispensers are services that manage nondurable shared-state architecture, on behalf of the application components within a process. This way, you don’t have to undertake traditional programming tasks associated with state maintenance.

Component Services works with any application development tool capable of producing COM-based dynamic-link libraries (DLLs). For example, you can use Visual Basic, Visual C++, Visual J++, or any other Microsoft® ActiveX® tool to develop Component Services applications.

Component Services is designed to work with a wide variety of resource managers, including relational database systems, file systems, and document storage systems. Developers and independent software vendors can select from a broad range of resource managers, and can use two or more within a single application.

The Component Services programming model simplifies migration, by making transaction application development easier and faster than traditional programming models allow. For more information about developing Component Services applications, see Data Access and Transactions in this book.
