An introduction to the field of computerized accounting information systems in organizations: basic transaction processing, record updating and maintenance, and financial and managerial reporting functions. Concentrates on the scope of accounting information systems in organizations; impacts of computerized accounting information systems on the role of the professional accountants; design issues for accounting information systems: security, accuracy, integrity, recovery, and operational control issues relating to accounting information systems; and impacts of computerized accounting information systems on the auditing processes in organizations. Prerequisites: ACCTG 311, 322, MIS 311. Credit may be granted for only one of ACCTG 437 or MIS 437.
Fall Term 2020An examination of the development of electronic commerce in business across a number of different sectors. Using a process modelling approach, traditional vs. electronic business transactions are discussed in business-to-business and business-to-consumer modes; strategies for e-commerce are developed with a focus on the appropriate technical architecture to support business in an electronic marketplace. In particular, requirements of payment systems, and issues of security and privacy are discussed as key considerations in implementation. The course uses software development tools in the implementation of these electronic commerce strategies. Prerequisite: MIS 311.
