Question;True / False Questions (1 point each)1. 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 ofaccounting 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 toimprove customer service, reduce production time, increase productivity, and improvedecision-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 whileone 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 developedin-house and to commercial software.10.

These are short answer questions that require a few sentencesto one paragraph to fully answer. Each response is worth 15 points.1. How does the database approach solve the problem of data redundancy?2. Define resources, economic events, and agents.3. Define ERP.4. Describe the three-tier client server model.5. What is a ping?6. Explain why accountants are interested in the legal feasibility of a new systems project.7. List three advantages and one disadvantage of commercial software.8.

These are essays and meant to be written in severalparagraphs. Each response is worth 15 points.1. One purpose of a database system is the easy sharing of data. But this ease of sharing canalso jeopardize security. Discuss at least three forms of access control designed to reduce thisrisk.2.
