DATAREADER Meaning and
Definition
-
A DataReader is a component or object in computer programming that allows read-only access to a database's data in a forward-only, stream-based manner. It is typically used to retrieve and process large amounts of data efficiently.
Specifically, a DataReader is used in conjunction with a connected database connection, such as in ADO.NET (ActiveX Data Objects for .NET). It is designed to provide a high-performance method of accessing and processing data without the need to load the entire data set into memory.
When retrieving data from a database, the DataReader provides a forward-only, sequential access to the result set. It reads one record at a time, allowing the developer to process the data in a more efficient manner, reducing memory footprint and improving performance. The DataReader is optimized for scenarios where the data is not modified at the client-side and only read operations are required.
The DataReader provides methods to access individual columns in each record and retrieve their values. This allows developers to perform actions such as iterating through each record, retrieving specific data based on column name or index, and converting the data to appropriate data types for further processing.
In summary, a DataReader is a specialized object used in database programming to efficiently retrieve large amounts of data in a forward-only, stream-based manner. It offers improved performance and reduced memory usage by providing read-only access to the data without loading the entire result set into memory.

Etymology of DATAREADER
The word "datareader" is composed of two parts: "data" and "reader".
The term "data" stems from the Latin word "datum", which means "something given or granted". It entered the English language in the mid-17th century, evolving from its Latin roots.
The word "reader" originated from the Old English word "rǣdere", which means "one who reads". Over time, it developed into the modern English term "reader", referring to a person who reads or peruses written works.
Therefore, the etymology of "datareader" can be understood as a combination of "data", denoting information or facts, and "reader", referring to a person or thing that reads or accesses that information. In the context of computer programming, a "datareader" is an object that reads data from a data source, such as a database.
