Enterprise Systems Architecture

Figure 18-1 shows the software systems of a highly integrated enterprise and their interactions with external software systems belonging to partners, customers, and service providers. Highly integrated enterprises use many kinds of software, including the following.

  • Enterprise resource planning (ERP)

    ERP systems typically include functionality for running the internal functions of the business in areas such as finance, human resources, manufacturing, and logistics.

  • Customer relationship management (CRM)

    CRM systems collectively are those responsible for marketing, sales, and service—every business aspect that touches the customer.

  • Data warehouse

    Data warehouse systems are repositories for the business information created by the various other systems in the enterprise. For example, sales data from the ERP system, component cost data from supply chain systems, and customer data from CRM systems may be collected together and used for decision making. Data warehouse systems have arisen for two main reasons. First, the various source systems typically are not designed to retain such information indefinitely. Second, by combining information from disparate systems, new correlations can be discovered.

  • Data mining

    Data mining refers to the practice of searching through large volumes of information (typically stored in data warehouses) to answer complex questions and to discover unexpected patterns in data.

  • Online analytical processing (OLAP)

    OLAP is closely related to a combination of data warehousing and data mining but has come to be used in those cases in which the data is represented in a multidimensional way to enable fast, interactive queries about the business.

  • Supply chain management (SCM)

    Supply chain management goes beyond the functionality of the manufacturing requirements planning modules of ERP systems to fully manage scheduling and acquisition of production material.

  • Sales force automation (SFA)

    Sales force automation includes lead tracking, forecasting, compensation, and other activities related to the sales force.

  • Maintenance, repair, and operations (MRO) procurement

    MRO systems are responsible for supplies not needed for product manufacturing. These may include anything from office supplies to plant repair parts. Buy-side Internet commerce systems help to solve these problems.

  • E-business

    These are the Internet-based systems this book is about: content management, catalogs, and transaction processing. E-business necessarily overlaps or connects with many other areas of enterprise software.
