Wat is data scrubben en waarom heb je het nodig?

If there’s one thing businesses have a lot of, it’s data, which is why data scrubbing has become such a vital practice. Your budget? Data. Your product inventory? Data. Your marketing metrics? You guessed it—data.

With so much data floating around your company, it takes a rigorous effort to keep it all accurate and organized. But, inconsistencies and inaccuracies can still pop up even when you go out of your way to manage your data efficiently. So, when that happens, what do you do?

Het antwoord is gegevens scrubben. Je gegevens scrubben is de beste manier om ze in topvorm te krijgen. Maar wat is datascrubben? Het antwoord is dat het het proces is van het opschonen van je gegevens. Lees verder voor meer informatie.

An introduction to data scrubbing

First, let’s take a look at the basics of data scrubbing and define what it means to scrub your data.

Wat is gegevens scrubben?

Data scrubbing is een proces waarbij je door de gegevens van je bedrijf gaat en rigoureus fouten wijzigt of verwijdert wanneer je ze vindt. Deze fouten kunnen te maken hebben met onnauwkeurigheid, inconsistentie, duplicatie of iets anders.

Gegevens scrubben vs. gegevens opschonen

Misschien heb je de term "gegevens opschonen" wel eens eerder gehoord. Als dat zo is, vraag je je misschien af of dat hetzelfde is als gegevens opschonen. Het antwoord is ongeveer hetzelfde.

Bij het opschonen van gegevens doorloop je je gegevens en herstel je alle duidelijke fouten die je ziet. Klinkt als gegevens opschonen, toch? Het verschil is echter dat gegevens opschonen veel meer inhoudt. Wanneer je je gegevens scrubt, ga je uiterst grondig te werk en zoek je doelbewust naar zelfs de kleinste fouten en verwijder je deze.

Op die manier is data scrubbing een vorm van data cleaning, maar het is veel diepgaander dan andere reinigingsmethoden.

In fact, data scrubbing even includes automated disk drive and storage system checks when storing data. Efficient scrubbing ensures your data is free from bad sectors and readable.

The importance of data scrubbing

Why is data scrubbing important for your business? Let’s discuss the benefits or regularly scrubbing your data.

Why is data scrubbing necessary?

Je vraagt je misschien af waarom het scrubben van gegevens zo noodzakelijk is. Het antwoord is dat je gegevens anders veel minder nuttig voor je zijn.

Hoe nauwgezet je ook te werk gaat bij het verzamelen en organiseren van gegevens, er zullen altijd fouten worden gemaakt. Het is onvermijdelijk dat bepaalde gegevens niet kloppen. En één onnauwkeurig gegeven is genoeg om alles in de war te sturen, vooral als je dat gegevenspunt gebruikt om andere statistieken te berekenen.

Plus, even where there aren’t outright mistakes, there could be formatting issues that cause data to get calculated differently, or excluded from calculations altogether, by the tools you use. Basically, data mistakes can cause huge problems for your company.

Maar data scrubbing geeft je een manier om al die fouten eruit te halen en jezelf ontelbare hoeveelheden moeite te besparen.

How does data scrubbing enhance data management?

Routine data cleansing can enhance all aspects of your data management systems. With accurate and relevant data on hand, you’ll improve:

  • Data integration: Format and standardize data before combining it with other clean data.
  • Data migration: Maintain data integrity as you transfer it from one system to another.
  • Data transformation: Convert data according to your formatting needs before you load it onto your system. 
  • Data extraction, transformation, and loading (ETL): Prepare data seamlessly for quality reporting and more effective analysis.

The benefits of data scrubbing for customer data management

Scrubbing your customer data has its advantages, including:

  • Improved customer communication: With accurate and relevant data at your fingertips, you can improve customer interactions and build trust.
  • Better decision-making: Error-free data makes it easier to pinpoint what’s working and areas that need improvement.
  • Improved business revenue: Reduce the time and money spent on miscommunication due to inaccurate data and ensure customers enjoy a positive experience, leading to more conversions.
  • Increased employee productivity: When data is accurate and easy to find, your employees are more efficient and produce better results.

Data scrubbing processes and techniques

Understanding the importance of data scrubbing is one thing. Knowing how to scrub data is another. But before we dive into the process, let’s break down the data discrepancies you should be on the lookout for.

Waar wordt data scrubbing voor gebruikt?

There are several types of mistakes you can use data scrubbing to fix. Some examples of the issues you can correct with data scrubbing include:

  • Duidelijke fouten: Soms zijn gegevenspunten gewoon niet nauwkeurig. Misschien zijn deze punten verkeerd getypt, verkeerd berekend of zijn ze om te beginnen niet goed gemeten.
  • Formatting issues: You might enter data points accurately but with the wrong formatting. For instance, if you’re entering percentages, you might input one as “75%” but then enter another one as “0.84” instead of “84%.”
  • Oude gegevens: Er kunnen momenten zijn waarop je een gegeven invoert, en op het moment van invoer is het accuraat. Maar dan, later, verandert er iets, maar niemand denkt eraan om die gegevensinvoer te wijzigen, dus worden ze verouderd.
  • Duplicate data: It’s relatively common for data to be inadvertently entered more than once into a database. Having repeat data can mess up a lot of calculations—for instance, a sale might get logged two different times, making you think you’ve earned more than you have.

Er zijn mogelijk nog andere soorten discrepanties in gegevens naast de hierboven genoemde. Als dit soort problemen zich in je databases en spreadsheets schuilhoudt, is het zeker de moeite waard om de tijd te nemen om deze problemen op te lossen en de betrouwbaarheid van je gegevens te verbeteren.

What does the data scrubbing process look like?

The scrubbing process may differ from one organization to the next. Ultimately, your process will depend on the type and extent of your data set and your analytics needs.

That said, scrubbing data will usually include these core steps:

  • Identify the issues: Inspect, audit, and profile the data to determine data relationships, quality, errors, and other issues.
  • Determine your requirements: Set some data rules that align with your business needs, like formatting guidelines and required fields. 
  • Scrub the data: Correct your data issues in line with your company’s requirements.
  • Check the data: Verify that the scrub was successful by checking the data for the discrepancies you picked up in step one and the rules you created in step two.
  • Document the results: Create a report showing the problems your data cleansing process identified and corrected and how it affected data quality.

After successful scrubbing, you can transfer your data to prepare it for analysis.

Scrubbing your data routinely is the best way to maintain data integrity over the long term. Most businesses should conduct a scrub every three to six months for consistent, quality data.

If you work with particularly sensitive data or store and analyze data at scale, it’s probably best to initiate a data scrub more frequently. A thorough scrub is always a good idea if you ever feel like your data’s integrity is compromised.

Who is responsible for data scrubbing?

Interested in learning more about job roles that typically include data scrubbing as part of their responsibilities? If you’re looking to employ someone to oversee and manage data in this way, you’ll need one of the following:

  • Data quality analyst
  • Data engineer
  • Data manager
  • Data scientist
  • Business intelligence (BI) analyst

What is data scrubbing in a RAID?

If you’re familiar with large-scale data storage practices, you’ll know exactly what a RAID is. 

For those less familiar, a RAID, or Redundant Array of Independent Disks, is a data storage technique used to store your data in multiple locations. This approach improves data storage performance, reliability, and protection.

Data scrubbing is also effective in a RAID—it reads all the data stored, identifies inconsistencies, and corrects them. Scrubbing tools can search for, repair, and rectify copied, unmatched, and invalid data when stored this way.

How do you scrub data in SQL?

When it comes to more complex data storage and transfer systems, ETL tools are commonplace. These tools help companies extract and load data through their data pipeline, seamlessly transforming it to meet their needs.

ETL tools use a data management programming language known as SQL to transform the data. Using separate software or processes to clean the data before transformation can complicate the process. 

ETL tools allow data engineers to write SQL for data scrubbing. This feature lets you simultaneously clean and transform your data, streamlining the operation.

Top data scrubbing tools and vendors

Odds are, your company has a vast amount of data to deal with. Given that fact, manually sorting through every single data entry would be an enormous pain. Thankfully, there’s no need to do everything manually.

You’ll find several different data scrubbing tools online that can automate a decent bit of the process. Here are three of the best data scrubbing tools out there!

1. OpenRefine

Prijs: Gratis

OpenRefine is a free, open-source tool for cleaning and altering data. You can use it to peruse your data for mistakes and edit existing data as needed, changing names and adding additional elements.

Another valuable OpenRefine feature is that it can translate numbers into numerical data. Often, tools translate numerical data as text rather than your tools recognizing it as numerical data that you can use in charts and spreadsheets. OpenRefine can identify numbers separately from other text, though.
