There is a saying in the database industry - GIGO. It stands for garbage in Garbage out. The point of a database is to maintain data in a way that it has a use. For example, in a business a database might be used for inventory. What good would it be if the database didn't contain the right information on quantity and price. Also when you sell something you would like to have its quantity decremented in the database. If this didn't happen reliably you have a big problem. There are other factors in data quality that might be associated with the precision of the data. For example you might have a piece of data stored as an integer, but find out later that you actual need floating point for more precision in your queries.
Database is defines as a collection related records/data. When the data in the database is grouped based on some classification it is called database clustering.
A relational database stores data in the form of TABLES.
No. A table is the primary object used within a database to store data. A typical database will consist of many tables.
Data anamaly means same type of data present in database as a duplication.So while updating or modifying the information in the database we gets the problem of data inconsistency to solve this problem we need to remove the duplicated data
The data should not be redundant and should be validated. The data or records should be interrelated.
The data type of a field determines the kind of data it can contain. For example, a field with a data type of "Text" can contain letters and numbers, while a field with a data type of "Number" can only contain numerical values. The data type is set when designing the database schema.
Data dependency in DBMS refers to the relationship between different data elements within a database. There are three main types: functional dependency (one attribute determines another), partial dependency (part of a composite key determines other attributes), and transitive dependency (dependency between non-key attributes). Understanding data dependencies is crucial for database normalization and maintaining data integrity.
Field characteristics in a database are used to define the properties and constraints of a specific field, such as data type, length, and validation rules. They help ensure data integrity, accuracy, and consistency within the database by specifying how data should be stored and validated. These characteristics help to maintain the quality and reliability of the data stored in the database.
Data integrity is crucial for a database because it ensures that the data stored is accurate, consistent, and reliable. It helps maintain the quality of the database and ensures that decisions made based on the data are valid and trustworthy. Without data integrity, there is a risk of errors, inconsistencies, and unreliable information, which can lead to incorrect analysis and decision-making.
A special database of cleansed data is often referred to as a data warehouse. It is a centralized repository that stores structured and processed data from different sources, making it easier for users to analyze and make informed decisions based on high-quality data.

A database is a collection of data. Data represents items that are stored within the database.
How do you validate and retrieve data from database?" How do you validate and retrieve data from database?"
The factors that determine the database you search include the type of information or data you are looking for, the relevance of the database to your topic or research, the quality and reliability of the database, and whether the database covers the specific subject area or discipline you are interested in.
We would use in rather than on. Data is stored in a database, not on a database. Data is entered into a database not onto a database.
