The Road to Data Preparation

Technology   |   Bertrand Cariou   |   May 7, 2021

Over the course of my career, I’ve used my fair share of technologies to clean and transform data. I enjoy coding and love SQL. I built ETL pipelines for 10 years. I still use Excel (and Google Sheets) quite often in my product marketing role at Trifacta. 

When I first discovered data preparation technologies, I had questions. 

Why should I adopt a new approach when there are already plenty of ways to clean and transform data? Is learning a whole new approach worth the time, expense, and effort? Are the old ways tired, and this new way wired?

The answer is an unequivocal yes. This blog is how I got there.

Coding: The Launch Point

I started my career as a software engineer developing a Customer Relationship Management (CRM) application. I developed a data loader to clean, standardize, and migrate customer data to a CRM system. I also created a reporting layer on top of the CRM to monitor user activities.

I know coding.


SQL: The Standard for the Client/Server Era

Back when Relational Database Management Systems (RDBMS) were taking off, SQL became the de facto standard to store and transform data. I have been a Microsoft certified trainer in SQL Server and spent years in SQL consulting. I even wrote a book on Transact SQL. 

I know SQL.


ETL: The Era of the Data Pipeline

I then co-founded the French distributor for Informatica, the ETL market leader. I stayed with Informatica for 15 years, helping it grow into a billion dollar company.  

I know ETL. 


Spreadsheets: The Perennial Workhorse

During my time in product management and product marketing at Informatica, I directed my product’s business unit to adopt a proper Business Intelligence framework and process, which was done manually in Excel (with many macros).

I know Excel.


Data Preparation: A New Standard for a New Era of Analytics

One day in 2010, I discovered Google Refine. It dramatically changed my thinking about transforming data. Not long after, I learned that a new market was forming around this new approach now known as data preparation, and a new company was emerging as a data preparation thought leader. I tried Trifacta products, and I never looked back. I was so sold on the technology that I I joined the company in 2015.

I still use Trifacta on the job nearly every day. Any time I need to clean, combine, or enrich data for my business, I leverage the Trifacta data preparation platform. It dramatically improves my ability to run my marketing campaigns and makes me a better, more efficient product marketer. 

From Tired to Wired: Comparing Data Transformation Technologies 

When it comes to cleaning and transforming data to prepare it for data acquisition, analytics, and machine learning/artificial intelligence initiatives, there’s no question that the old approaches are tired. The Trifacta approach to data preparation is wired.
