Answer 2

Data record within a table

A row in a relational database when mapped to columnar database would be represented as a data record within a table.

• A row in a relational database is a data record that is contained in a table. Within the same structure, each row, which represents a full record of information about a single item, has different information. Sometimes a row is referred to as a tuple.
• A table of values is what the relational data model depicts (or data table). As a result, each row of the table represents a group of connected data values and often correlates to an entity or connection in the actual world. A row is formally referred to as a tuple.
• Rows are regarded as records with fields in DBMSs. In DBMS, columns that contain a group of characters are referred to as fields. The horizontal arrays of a matrix are also known as rows. The vertical arrays of a matrix are sometimes known as columns.
• All data is stored in tables, which are composed of rows and columns, in a relational database. A unique datatype—such as an integer number, a string of characters (for text), or a date—is allocated to each column in a table, which may have one or more columns. The table's rows each contain a value for a certain column.
