===Notes===
A data analyst translates data into insights to improve and refine the (business) processes [1][2][3]. In addition, business decisions will depend on his or her analyses [3].

Responsiblities of a data analyst are: [2]

  * Analyzing data and interpreting results – this involves identifying trends or patterns in data that can help in making informed decisions. 
  * Communicating analysed results to teams through visualizations or written reports.

The data quality analyst’s duties may vary. The specialist may perform the data consumer’s duties, such as data standard definition and documentation, maintain the quality of data before it’s loaded into a data warehouse (which is usually the data custodian’s work) [1].

  * Monitoring and reviewing the quality (accuracy, integrity) of data that users enter into company systems, data that are extracted, transformed and loaded into a data warehouse.
  * Identifying the root cause of data issues and solving them.
  * Measuring and reporting to management on data quality assessment results and ongoing data quality improvement.
