Hvad er data scrubbing, og hvorfor har du brug for det?

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?

Svaret er skrubning af data. At skrubbe dine data er den bedste måde at få dem i tip-top form på. Men hvad er data scrubbing? Svaret er, at det er processen med at rydde op i dine data. Læs videre for at finde ud af mere.

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.

Hvad er data scrubbing?

Data scrubbing er en proces, hvor man gennemgår sin virksomheds data og grundigt ændrer eller fjerner fejl, efterhånden som man finder dem. Disse fejl kan have at gøre med unøjagtighed, inkonsekvens, duplikering eller noget helt andet.

Datascrubbing vs. datarensning

Du har måske hørt udtrykket "datarensning" før. Hvis det er tilfældet, spekulerer du måske på, om det er det samme som data scrubbing. Svaret er lidt af det samme.

Datarengøring er, når du gennemgår dine data og retter eventuelle åbenlyse fejl, du ser. Det lyder som data scrubbing, ikke? Forskellen er dog, at data scrubbing er langt mere involveret. Når du renser dine data, er du ekstremt grundig og søger bevidst efter og fjerner selv de mindste fejl.

På den måde er data scrubbing en form for datarensning, men den er meget mere dybdegående end andre rensningsmetoder.

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?

Du undrer dig måske over, hvorfor datascrubbing er så nødvendigt. Svaret er, at uden det vil dine data være langt mindre nyttige for dig.

Uanset hvor omhyggelig du er med at indsamle og organisere data, vil der stadig slippe fejl igennem. Der vil uundgåeligt være visse data, der ikke er nøjagtige. Og ét unøjagtigt stykke data er nok til at ødelægge alt, især hvis du bruger det datapunkt til at beregne andre målinger.

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.

Men data scrubbing giver dig en måde at udrydde alle disse fejl på og spare dig selv for utallige problemer.

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.

Hvad bruges data scrubbing til at løse?

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:

  • Direkte fejl: Nogle gange er datapunkter simpelthen ikke nøjagtige. Måske er disse punkter skrevet forkert, beregnet forkert eller ikke målt ordentligt til at begynde med.
  • 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%.”
  • Gamle data: Der kan være tidspunkter, hvor du indtaster et datapunkt, og på indtastningstidspunktet er det nøjagtigt. Men senere sker der noget, men ingen tænker på at ændre indtastningen, så den bliver forældet.
  • 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.

Der er potentielt andre typer dataafvigelser derude ud over dem, der er nævnt ovenfor. Hvis den slags problemer gemmer sig i dine databaser og regneark, er det bestemt værd at tage sig tid til at fjerne dem og forbedre pålideligheden af dine data.

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

Pris: 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.
