Master cleansing is highly recommended for any organization dealing with data daily. It involves getting rid of unwanted observations –removing observations that aren’t relevant to the problem you’re trying to solve.
To begin with, maintaining data quality is a severe task for organization data aggregators. They invest heavily in keeping contact lists, profiles, products, customers, sales, demographics, and other data clean, accurate, and up to date. According to HBR, 47% of newly created data records contain at least one significant error that interferes with work. And we’re talking about new data in databases here, not old documents that everyone knows need cleaning up and enrichment.
Validation of high-quality data gathered from various sources is required, making data cleansing a mandatory and ongoing operation for data aggregators. You can keep your master data clean by doing the following:
- Standardizing your data: This involves ensuring the numerical observations in your dataset use the same unit of another measurement.
- Removing unwanted outliers: Outliers can be helpful, but if they’re incorrect, You’ll need to decide which outliers to keep and the ones to let go.
- Fixing cross-set data errors: Data rarely comes from a single source; ensuring that different data sources don’t contradict each other is vital.
- It would be best to resolve conversion and syntax errors involving removing whitespace, checking for spelling mistakes, or ensuring your data is categorized correctly. For instance, numbers are appropriately labeled as numerical data, not the other way.
- Missing data: If missing outputs exist, you need to know what effect this will have on your master data. The data steward can choose to remove associated entries, guess missing values, or get them flagged for you to measure their impact later on.
For an introduction to data cleansing, check out the Synopps data cleansing site for how to go about it. This article will help you with the best tool for a master data cleansing assistant.
OpenRefine (formerly Google Refine) is a helpful tool for working with untidy data, such as cleaning it, converting it to another format, and extending it with online services and external data.
OpenRefine always keeps your data private on your computer until YOU decide to share or cooperate with it. Unless you want it to, your data never leaves your computer. (It works by running a small server on your computer and interacting with it via your web browser.) Another significant advantage is that you may work with data on your machine, which is secure. Of course, if you wish to connect or expand, You can achieve this by connecting OpenRefine to other web services and other cloud sources. If required, you can also upload your data to a central database, such as Wikidata. However, while OpenRefine simplifies many hard processes (for example, by using clustering techniques), it does necessitate some technical knowledge.
