A data field that contains unique information for each record?
A data field that contains unique information for each record is often referred to as a primary key in a database. This key ensures that each entry can be distinctly identified, preventing duplicate records and maintaining data integrity. Common examples include Social Security numbers, employee IDs, or unique usernames. By using a primary key, databases can efficiently manage and retrieve data associated with specific records.
Differentiate Between data coupling and control coupling?
Control coupling:Control coupling is one module controlling the flow of another, by passing it information on what to do (e.g., passing a what-to-do flag) Data coupling:Data coupling is when modules share data through, for example, parameters. Each datum is an elementary piece, and these are the only data shared (e.g., passing an integer to a function that computes a square root)
What are hierarchical databases and give me some examples?
A hierarchical database model is a data model in which the data is organized into a tree-like structure. The structure allows representing information using parent/child relationships: each parent can have many children, but each child has only one parent.
What are the differences in data and information?
They are synonyms of each other. There is no difference.
What are the differences between data, information, and knowledge, and how do they relate to each other?
Data refers to raw facts and figures, while information is processed data that has context and meaning. Knowledge is the understanding and application of information. Data is the foundation, information is the interpretation, and knowledge is the utilization of both.
What the differnce between data and information?
Data is stored on a hard drive, information is stored in your brain. But, at times they are used to mean each other.
What are three examples of information?
Three examples of information include weather forecasts, which provide data about expected conditions; financial reports, which detail a company's performance and health; and educational materials, such as textbooks or online courses, that convey knowledge on specific subjects. Each type of information serves to inform decision-making and increase understanding in various contexts.
What are the similarities between data management and information management?
The two are very similar and overlap each other. The difference is that while information is data, data is not necessarily information. Data may be hidden or be in a machine-readable format while information is generally exposed and in a human-readable format.
What contains data about each file in the database and each field within those files?
The data dictionary contains information about each file in the database, including the structure, properties, and location of each file. It also includes information about each field within those files, such as the data type, size, and constraints associated with each field. The data dictionary acts as a centralized repository of metadata that helps in managing and understanding the database schema and data.
