An attribute identifies a specific piece of information that the driver needs to know before it can make the appropriate data source connection.

LINQ to SQL maps a SQL Server database to a LINQ to SQL object model by either applying attributes or by using an external mapping file. This topic outlines the attribute-based approach. In its most elementary form, LINQ to SQL maps a database to a DataContext , a table to a class, and columns and relationships to properties on those classes. The attribute is generally used to prevent incomplete SQL statements from being processed when the SQL files contain statements referencing a ; which Liquibase treats as the default end delimiter. There is a corresponding rollbackEndDelimiter that applies specifically to rollback for sql and sqlFile Change Type s. So, in other words, this is the data wrangling approach in which the Data Scientist \ Data Wrangler decides to detach (remove) an attribute from the Dataset (such as a SQL table as a data source) on the basis of its rare or non-use for the upcoming data analysis.
