Operational Data: Data quality is one of the key features of enterprise data management. The data obtained from the operational system is low quality data because of the following reasons: Obtaining the data from outside the organization. Redundant storage of data and inconsistent metadata. Problems while entering data due to poor interfaces, manual mistypes of data. The poor quality of the data is not recognized by the organization itself is an issue. Data warehouse: Data warehouse contains the collection of data that are used for decision making and business intelligence. It is a unique kind of database so it focuses on business intelligence, time variant data, and external data. It is a subject-oriented, integrated, time-variant, and non-updateable data.

We want to get an idea of how many tickets we have and what our issues are. Print the ticket ID number, ticket description, ticket priority, ticket status, and, if the information is available, employee first name assigned to it for our records. Include all tickets regardless of whether they have been assigned to an employee or not. Sort it alphabetically by ticket status, and then numerically by ticket ID, with the lower ticket IDs on top.

Figure 1 shows an ASM chart representing the operation of a controller. Stateassignments for each state are indicated in square brackets for [Q1, Q0].Using the ASM design technique:(a) Produce a State Transition Table from the ASM Chart in Figure 1.(b) Extract minimised Boolean expressions from your state transition tablefor Q1, Q0, DISPATCH and REJECT.
