A business rules engine (BRE) is a software tool that helps businesses automate the process of making decisions. BREs are used in a wide variety of industries, including finance, healthcare, and manufacturing. They can be used to improve efficiency, reduce costs, and increase compliance.
Building a BRE can be a complex and time-consuming process. However, there are a number of resources available to help you get started. Many software vendors offer BREs as a commercial product. There are also a number of open source BREs available.
