(computer science) The way that the physical properties of a medium are used to represent data. The manner in which data is expressed symbolically by binary digits in a computer.
Representation of data refers to the way information is structured and displayed in a format that can be easily understood and processed by machines or humans. This can include using tables, charts, graphs, or other visual aids to present data in a meaningful way for analysis and decision-making.
A schema separates the physical aspect of data storagefrom the logical aspects of data representation.
Data refinement is the process of transforming a set of abstract data items into a more detailed and concrete representation. It involves refining the initial data specification by adding more specific details or attributes to meet the requirements of a system or application. This helps in creating a more accurate and detailed representation of the data that can be used effectively in software development or data analysis.
External representation of data refers to how information is presented or encoded in a format that can be accessed or understood by users or systems outside of its original source. This can include visual representations, such as graphs, charts, or tables, as well as file formats, such as PDFs or spreadsheets, that allow for sharing and manipulation of the data.
A logical unit of data is a virtual representation of data while a physical unit of data is the actual storage of data on a physical device. The logical unit of data is how data is organized and manipulated from a software perspective, while the physical unit of data is how data is stored on hardware such as disks or memory.
One-to-many relationships. In the table representation, the many-side entity will have repeated data related to the one-side entity, causing redundancy. By normalizing the tables, this redundancy can be reduced.
What is the visual representation of worksheet data?
The term for a visual representation of data is a data visualization.
A chart is a visual representation of data in Excel.
Data is information that is interpreted by a collection (Representation) of explanatory words or symbols. A simple explanation is a 60mph sign at the side of the road. The figure 60 is the data while the sign embossed with 60 is the representation informing you of that which you need to know. Traffic lights are a representation that tells you by the data of different colours what you you need to know. @ is a representation of the data "at"

A chart is a graphical representation of data, in which the data is represented by symbols, such as:bars in a bar chartlines in a line chartslices in a pie chart
Data representation is defined as the various methods that that used to show information. Various mediums like computers are used to represent data.
