For an instructor lead, in-depth look at learning SQL click below.
Structured Query Language (SQL) is a specialized programming language designed for managing and manipulating databases. It forms the backbone of any effective data governance strategy and plays a vital role in ensuring data compliance. SQL does this by providing powerful querying capabilities, enabling the implementation of security measures, and aiding in the process of data cleaning.
The Power of SQL in Data Querying
The first attribute of SQL that makes it effective in data governance and compliance is its powerful ability to query large data sets. With the appropriate SQL commands, you can easily filter, sort, and analyze data to make it compliant with specific regulations. Additionally, SQL queries allow for data auditing which is a crucial aspect of data governance.
