Tables and figures are both visual aids that are used to make data and information more accessible and understandable. The primary distinction between tables and figures is how information is displayed. A table is used to display data in a numerical or categorical. It is a structured collection of data that is organized in rows and columns. It is used to compare the two or more sets of data. A figure is a graphical representation of data such as map, graph, image, or illustration. They're especially useful for communicating complex information or data that's delicate to describe verbally. ... Read More

Introduction Functional dependencies and normalization are important concepts in relational database design. A functional dependency occurs when the value of one attribute determines the value of another attribute. Normalization is the process of organizing a database in a way that reduces redundancy and dependency. It is a crucial step in designing an efficient and effective database structure. What are functional dependencies? Functional dependencies are relationships between attributes in a database. They describe how one attribute is dependent on another attribute. For example, consider a database of employee records. The employee's ID number might be functionally dependent on their name because ... Read More

Updated on 10-Jan-2023 17:14:04


Data generalization, also known as data summarization or data compression, is the process of reducing the complexity of large datasets by identifying and representing patterns in the data in a more simplified form. This is typically done in order to make the data more manageable and easier to analyze and interpret. Introduction to Data Generalization Data generalization is a crucial step in the data analysis process, as it allows us to make sense of large and complex datasets by identifying patterns and trends that may not be immediately apparent. By simplifying the data, we can more easily identify relationships, classify ... Read More
