Identify trends/patterns. Evaluate alternatives. Support decision making. Assist in corrective action. © 2003, Educational Institute 3 Management Information System—Functions Enables managers to monitor/administer transactions/ activities Provides control over business resources Produces timely/comprehensive reports formatted to managers’ needs Eliminates unnecessary documents Streamlines procedures © 2003, Educational Institute 4 Electronic Data Processing Transforms data into timely, accurate, and useful information by reducing throughput, streamlining output, and minimizing the handling of data. Throughput: the time elapsing between data input and information output, a measure of data processing efficiency Streamlining: only generating output (reports) requested by those who actually use the information © 2003, Educational Institute 5 Bits and Bytes Bit: smallest unit of electronic data (either 0 or 1) Byte: sequence of bits representing a single character and a measurement of memory Kilobyte 1,024 bytes Megabyte 1,048,576 bytes Gigabyte 1,073,741,834 bytes Terabyte approximately 1 trillion bytes © 2003, Educational Institute 6 Database Management Features Files, records, fields Create, access, and merge data files Add, select, and delete data Index, sort, and search data files © 2003, Educational Institute 7 Database Management Hospitality Functions Personnel management Payroll processing Marketing research General ledger accounting Tax reporting Direct mail marketing Sales reporting © 2003, Educational Institute 8 Hierarchical Database Structures Files, records, fields arranged like roots of a tree Precise data searches Comprehensive statistical analyses Rigid perameters Time-consuming to incorporate new data definitions © 2003, Educational Institute 9 Relational Database Structures Files, records, fields formatted as rectangular tables of rows/columns Popular due to simplicity of data arrangement Ease of data manipulation Flexibility of data handling © 2003, Educational Institute 10 Multidimensional Databases Data warehouse: supports organization-wide decision making enabling elaborate queries on large amounts of data requiring extensive searching Data mart: a multidimensional database organized for one department or function Data mining: exploring a database to uncover patterns and relationships Online analytical processing (OLAP): decision support software enabling a user to quickly analyze information summarized into multidimensional views and hierarchies © 2003, Educational Institute 11
