Final answer:
Database reports are used to create summaries, and can include tables, graphs, and charts such as pie charts for showing parts of a whole and bar graphs for comparing quantities.
Step-by-step explanation:
Database reports are valuable tools for interpreting and presenting data effectively. When it comes to providing details about individual records, database reports are utilized to create summaries. However, reports can also include other forms of data presentation such as tables, which organize data in a systematic, linear manner making it easier to find specific data points. Additionally, reports often incorporate graphs and charts which can be instrumental in understanding data relationships and comparisons.
Pie charts are particularly useful for showing parts of a whole by illustrating categories of data as wedges in a circle, representing the percent of individuals or items in each category. On the other hand, bar graphs excel at comparing quantities, such as the population sizes of different countries or the breakdown of groups within a population. Each type of graph and chart plays a unique role in data presentation, depending on the nature and requirements of the information.
