Detailed explanation-1: -A tuple is a single row in a database that contains a single record for such a relation. A row or record is another name for a single item in a table, which is what a triple is. In math, they simply consist of an ordered list of elements and typically represent a set of connected data.
Detailed explanation-2: -They are the same. A row-also called a record or tuple-represents a single, implicitly structured data item in a table.
Detailed explanation-3: -In relational databases, a tuple is one record (one row). The information in a database can be thought of as a spreadsheet, with columns (known as fields or attributes) representing different categories of information, and tuples (rows) representing all the information from each field associated with a single record.
Detailed explanation-4: -Tuple is used to refer to a row in a relational database model.
Detailed explanation-5: -The relational data model represents a table of values (or data table). Each row of the table, therefore, represents a collection of related data values and hence typically corresponds to real world entity or relationship. Formally, a row is called a tuple.
