Data Profiling Column Functional Dependency T Sql Sqlservercentral

Data Profiling Column Functional Dependency T Sql Sqlservercentral First let’s define functional dependency. determines the extent to which the values in one column (the dependent column) depend on the values in another column or set of columns (the. A functional dependency profile reports the extent to which the values in one column (the dependent column) depend on the values in another column or set of columns (the determinant column). this profile can also help you identify problems in your data such as invalid values.

Assuming, then, that you accept the premise that profiling your data can be a good idea, here is a simple way to carry out basic data profiling on sql server tables. David loshin describes the benefits of the combination of the bottom up aspects of data profiling with a top down analysis phase for establishing criteria for data quality management. I need to do some of the following profiles using t sql queries, i have three tables that i need to profile: are there any basic queries for the following profiles?.

Reports the extent to which the values in one column (the dependent column) depend on the values in another column or set of columns (the determinant column). this profile also helps you identify problems in your data, such as values that are not valid. Sql server 2008 has a new feature in ssis: data profiler. for a given table, data profiler enables us to understand the number of distinct values in each column, and the distribution. To view the data profiles that the data profiling task computes, you send the output to a file, and then you use the data profile viewer. this viewer is a stand alone utility that displays the profile output in both summary and detail format with optional drilldown capability. For the three profile types that are computed against more than one column (candidate key, functional dependency, and value inclusion), the details pane displays violations of the expected relationship.
