Data Quality Analyst

What is a Data Quality Analyst?

Skills That Set Them Apart



Technical: Using computational theories and applications that may include data mining and the use of analytic models, data warehouse set-up, statistics and/or relational algebra, and specific programming languages.



Working with internal and external team members to measure, monitor and improve data quality.



Identifying and reporting on the complex relationships between the technology and information, providing projections and predictions, cost analysis, impact and error detection.

Specialized Training

The Educational Foundation That Sets the Stage



Skills in leveraging the power of data wrangling tools such as Alteryx are essential for a Data Quality Analyst.



Free open source tools are increasing being used to perform data quality analysis. Those include tools such as KNIME, Talend and Pentaho.



Data Quality Analysts should know how to execute complex queries in SQL (structured query language).



What scripting language should a Data Quality Analyst learn? According to one source, JavaScript was cited as the most used scripting language.



Data Quality Analysts are often required to know Python, , as well as Java, Perl and C/C++. Python is relatively easy to learn, and it is supported by an active community. Python has been gaining on R in popularity in recent years, though both of these open-source languages are popular.



Data Quality Analysts may want to add NoSQL such as MongoDB or HBase to their skillset, as these systems work quickly with large volumes of data and are easily scalable for a more customized approach.


Non-traditional Data Corralled with Fuzzy Logic

Unstructured data from reviews, social media comments and email can be a gold mine of information for Data Quality Analysts, but it doesn’t always fit neatly into traditional data tables. That’s why they may need to leverage the capabilities of  ELT.

Data Visualization Tools

Being able to communicate their findings is a key responsibility for Data Quality Analysts, and in order to do so, they need to know which tools will work best for their applications.


Tableau is an essential software package that can present the data and showcase the derived insights. It allows Data Quality Analysts to show the results in a variety of visual formats.


ggplot2 allows Data Quality Analysts to plot trends on a graph with unique color-coding to help distinguish between key points. The findings can then be processed directly as a PDF or object that can be easily disseminated to shareholders.


FusionCharts is a JavaScript-based formatting software that charts both web and mobile platform data into three-dimensional graphs. According to New Gen Apps, more than 80% of Fortune 500 companies use it.
