Information About Data Cleaning And Data Services

Data Cleaning from NW Database Services

Data Accuracy

Accuracy can simply be described as the accuracy of your data. This could include anything, from your birth date to your bank balance, eye color or geographic location. Because data accuracy is critical, it can impact the results of any analysis and subsequent business decisions. It’s difficult to determine accuracy because it can’t be measured against existing datasets that are ‘gold standards’.

Data Completeness

Data completeness refers to how extensive a dataset is. Do you have the right information to complete your task? It’s not always easy to identify an incomplete data set. Let’s suppose you have a customer database but only half of the surnames are included. The dataset would not be complete if you wanted to list customers alphabetically. Surnames would not matter if you were only trying to find geographical locators by analysing customer dialing codes. Incomplete data is difficult to correct, just like data accuracy. Because it is not always possible to infer missing information based on the data you have,

Data Consistency

Data consistency is the ability to match data from different sources. This is what determines the reliability of your data. If you work in a doctor’s office, you might find patients with two different phone numbers or postal addresses. These data are inconsistent. Smart thinking is required to determine data consistency. It is not always possible to go back to the source. It is possible to determine which data are correct by looking at most recent entries or by using another method of determining reliability.

Data Uniformity

Data uniformity is a measurement of units, metrics, etc. Imagine that you combine two datasets about people’s weight. The metric system is used in one dataset, while the imperial system is used in the other. All measurements must be consistent in order for the data to be useful during analysis. All measurements must be in kilograms or pounds. It is possible to convert it all into one unit. This aspect of data quality is much easier to manage. This doesn’t necessarily mean filling in the gaps or determining accuracy… phew!

Relevance of Data

Data relevance is a subjective indicator of data quality. It measures whether the data is complete, consistent, and uniform to meet its task. Timing is another aspect of data relevance. Is the data readily available when you require it? Are all people able to access it? If you report to the Board quarterly profits or losses, then you will need the most current information. You can only provide lower-quality insights if you have only the last quarter’s data.

Northwest Database Services has 34+ years experience with all types of data services, including mail presorts, NCOA, and data deduplication. If your database systems are not returning poor data, it is definitely time for you to consult with a data services specialist. We have experience with large and small data sets. Often, data requires extensive manipulation to remove corrupt data and restore the database to proper functionality. Call us at (360)841-8168 for a consultation and get the process of data cleaning started as soon as possible.
