3

What are the ways in which information is classified in terms of structure? Explain with examples

Information is classified into three types, based on how ordered and organized it is. Facts and data that are reasonably ordered, can be broken down into component parts, and organized into hierarchies are called structured information. For example, a credit card company maintains customer records in a structured format with elements such as last name, first name, street address, phone number, and email address.
Information that has no inherent structure or order is called unstructured information. For example, a manila folder in which educational certificates, employment records, bills, warranties, and medical prescriptions are stored.
The information category that falls between structured and unstructured information is called semi-structured information. It includes facts and data that show at least some structure, such as web pages and documents, which bear creation dates, titles, and authors.

Explain, with an example, how data might be aggregated and analyzed to create information and knowledge

The term data refers to individual facts or pieces of information and information refers to data or facts that are assembled and analyzed to add meaning and usefulness. For example, a single high-temperature reading of an incoming patient at Patient First, a 24-hour walk-in clinic in Laurel, Maryland, is one piece of data. But entered into the patient records information system, and combined with the patient's other symptoms and previous medical records, it becomes far more valuable as a diagnostic tool. Even more value can be obtained from this one temperature reading by aggregating it with the data from other patients entering the clinic that week. Tables and charts constructed from these data, analyzed by geographic region, may indicate a flu epidemic or the first signs of a pandemic emergency. As information from many clinics, emergency rooms, and doctors' offices pours in and the public health staff at the Centers for Disease Control in Atlanta analyzes maps, patient diagnoses, and many other facts, a pattern may emerge that warrants swift action.
Information can be further refined, analyzed, and combined to make it even more useful, and extremely valuable. No clear dividing lines separate these categories, and people often use the terms interchangeably. They blend together and form a continuum as more meaning and usefulness are created through analysis and skillful combination of many sources of data and human insight.

Briefly describe the function of an application program in a database system

The application program is responsible for creating and processing forms. The application displays the form to the user, allows the user to complete the data entry, evaluates the form to determine which data management tasks need to be performed, and transmits the appropriate requests to the DBMS. The application creates and transmits queries. The queries are requests for data that are created in a language like SQL, and transmitted to the DBMS to have the requested data returned to the application program. The application also creates and processes reports. The query to retrieve the necessary data for the report is sent to the DBMS. When the DBMS returns the needed data, the application manipulates it as necessary to create the requested report. The application program also applies application logic to control the manipulation of data in accordance with the business rules. Finally, the application program is responsible for providing control. Control must be exercised to allow the users to make choices for functions and tasks as appropriate for their jobs. Also, control must be exercised to manage the activities of the DBMS.
