Cross-Functional Enterprise Applications Why does company use IT to build cross- functional enterprise systems? IT is used to share information resources and improve the efficiency and effectiveness of business processes, and develop strategic relationships with customers, suppliers, and business partners. What function does company move from? Company moved from functional mainframe- based legacy systems to integrated cross- functional client/server applications.

enterprise application architecture presents an overview of the major cross- functional enterprise applications and their interrelationships. Enterprise Resource Planning (ERP) concentrates on the efficiency of a firm’s internal production, distribution, and financial processes. Customer Relationship Management (CRM) focuses on acquiring and retaining profitable customers via marketing, sales, and service processes. Partner Relationship Management (PRM) aims to acquire and retain partners who can enhance the sale and distribution of a firm’s products and services. Supply Chain Management (SCM) focuses on developing the most efficient and effective sourcing and procurement processes with suppliers for the products and services that a business needs. Knowledge management (KM) applications provide a firm’s employees with tools that support group collaboration and decision support.

Enterprise Application Integration(EIA) How does a business interconnect some of the cross- functional enterprise systems? EAI software is being used by many companies to connect their major e- business applications. Feature of EIA: – It provides middleware that performs data conversion and coordination, application communication and messaging services, and access to the application interfaces involved. – EAI software can integrate a variety of enterprise application clusters by letting them exchange data according to rules derived from the business process models developed by users.

Enterprise application integration software interconnects front-office and back-office applications

how EAI middleware connects several business information systems within a company.

Transaction Processing Systems(TPS) Transaction processing systems play a vital role in supporting the operations of most companies today. Many firms are using the Internet and other networks that tie them electronically to their customers or suppliers for online transaction processing (OLTP). The Transaction Processing Cycle: – Data Entry: To capture of business data. – Transaction Processing: They process data in two basic ways: (1) batch processing, where transaction data are accumulated over a period of time and processed periodically, and (2) real-time processing (also called online processing), where data are processed immediately after a transaction occurs. – Database Maintenance: An organization’s databases must be updated by its transaction processing systems so that they are always correct and up-to-date. – Document and Report Generation: Transaction processing systems produce a variety of documents and reports. – Inquiry Processing: Many transaction processing systems allow you to use the Internet, intranets, extranets, and Web browsers or database management query languages to make inquiries and receive responses concerning the results of transaction processing activity.

Enterprise Collaboration Systems (ECS) ECS are cross-functional information systems that enhance communication, coordination, and collaboration among the members of business teams and workgroups. The goal of enterprise collaboration systems is to enable us to work together more easily and effectively by helping us to: – Communicate: Share information with each other. – Coordinate: Organize our individual work efforts and use of resources. – Collaborate: Work together cooperatively on joint projects and assignments. Tools for Enterprise Collaboration: – Electronic communication tools include , voice mail, faxing, Web publishing, bulletin board systems, paging, and Internet phone systems. – Electronic conferencing tools help people communicate and collaborate as they work together. – Collaborative work management tools help people accomplish or manage group work activities. This category of software includes calendaring and scheduling tools, task and project management, workflow systems, and knowledge management tools.
