Chapter 15 ERP Systems and E-Commerce: Intra- and Inter- Enterprise Modeling Review Questions R1. Explain the three conditions that must be met to satisfy a database orientation. A database orientation requires the following three conditions to be met Data must be stored at their most primitive levels, at least for a defined time period. Data must be stored only once, and such that all authorized decision makers can access the data. Data must be stored so as to allow retrieval in various formats as needed for different purposes. R2. Bolt-on applications and best of breed software are both concepts associated with ERP software. What is the difference between these concepts? Bolt-on applications are non-ERP software programs that can be added to existing ERP software applications to provide additional functionality. Best of breed software is the use of modules from various ERP software packages in conjunction with each other rather than using modules from only a single ERP software package. Some differences are that bolt-on applications are used to provide functionality not typically found in any of the ERP software packages and the bolt-on applications are typically created by non-ERP vendors. R3. What is the difference between intra-enterprise integration and inter-enterprise integration? Intra-enterprise integration refers to integration within a single enterprise and inter-enterprise integration refers to integration of different enterprises. Intra- enterprise integration requires cooperation of different departments or functional areas within an enterprise; whereas inter-enterprise integration requires cooperation among different enterprises.

The systems and activities external partners normally do see are referred to as “front-office” systems and activities. For example, activities and systems used in the sales showroom are front-office dealings because customers see and interact with them. R6. To what extent is B2C e-commerce different from B2C commerce? B2C e-commerce is not significantly different from B2C commerce without electronics, e.g. via catalog mail orders, telephone orders, or customer pickup. In those scenarios a customer inquires (or is informed through a marketing event) about goods or services, the customer places an order for goods or services to be delivered, the enterprise delivers the goods or services to the customer, and the customer renders payment to the enterprise for the goods or services.
