The database approach to data management is sometimes called the flat file approach.2. A lockout is a software control that prevents multiple users from simultaneous access to data.3. According to the REA philosophy, information systems should support only the needs of accounting professionals.4. Modern managers need both financial and nonfinancial information that traditional GAAP-based accounting systems are incapable of providing.5. The primary goal of installing an ERP system is achieving business process reengineering to improve customer service, reduce production time, increase productivity, and improve decision-making.6. Organizations using ERP systems employ an internal control tool called a role.7. The network paradox is that networks exist to provide user access to shared resources while one of its most important objectives is to control access.8. The rules that make it possible for users of networks to communicate are called protocols.9. All of the steps in the Systems Development Life Cycle apply to software that is developed in-house and to commercial software.10. A qualified opinion on management?s assessment of internal controls over the financial reporting system necessitates a qualified opinion on the financial statements?Multiple Choice Questions (2 points each)1. Which of the following is not a problem usually associated with the flat-file approach to data management?a.data redundancyb.restricting access to data to the primary userc.data storaged.currency of information2.

Auditors of ERP systemsa.need not worry about segregation of duties.b.may feel that the data warehouse is too clean and free from errors.c.find independent verification easy.d.need not worry about system access since the ERP determines it.14. Legacy systems area.old manual systems that are still in place.b.flat file mainframe systems developed before client-server computing became standard.c.stable database systems after debugging.d.advanced systems without a data warehouse.15.
