What’s the Difference Between Validation &Data Verification Service That You Should Know
Data Verification Serviceand data validation may appear to be the same thing in layman’s terms. However, when it comes to the complexities of data quality, these two critical elements of the jigsaw are vastly different. Understanding the difference might help you grasp the overall picture of data quality.
What is the definition of a Data Verification Service?
In a word, data validation is the act of verifying whether a certain piece of data fits inside a field’s permitted range of values. Every street address in the United States Data Verification Service, for example, should have a separate entry for the state. Certain values, such as NH, ND, AK, and TX, adhere to the United States Postal Service’s list of state abbreviations. Those acronyms, as you may know, designate certain states.
Guam (“GU”) and the Northern Mariana Islands (“MP”) are examples of two-character abbreviations for US territory. If you put “ZP” or “A7” in the state box, you’re effectively invalidating the entire address because those states and territories don’t exist. Data Verification Servicewould include comparing existing values in a database to confirm that they are within acceptable bounds.
The state/province/territory column would need to be checked against a much wider list of potential values if the list of addresses included nations beyond the United States, but the underlying principle remains the same: the values submitted must fit within a list or range of permitted values. (As an aside, precisely provides address validation services.)
For example, you might need to define restrictions around acceptable numeric values for a certain field in some circumstancesData Verification Service, but with a little less accuracy than in the preceding example. If you’re measuring someone’s height, you might wish to exclude numbers that are outside the anticipated range. You may certainly presume the data in your database is wrong if a person is reported as being 12 feet tall (approximately 3 meters). You wouldn’t want to allow negative integers in that field, either.
Fortunately, validation tests like this are usually conducted at the application or database levelData Verification Service. If you’re putting a US-based shipping address into an e-commerce website, for example, you’re unlikely to be able to input a state code that isn’t legitimate for the US.
How is Data Verification Servicebeing different from data validation?
Data verification, on the other hand, differs from data validation in several ways. Verification examines existing data to confirm that it is correct, consistent, and serves the intended purpose.
Verification might take place at any time. To put it another way, verification can happen as part of an ongoing data quality processData Verification Service, whereas validation usually happens when a record is produced or modified for the first time.
When data is moved or combined from external data sources, verification is very important. Consider a corporation that has recently bought a tiny competitor. They’ve opted to include the client data from the purchased rival into their invoicing system. It’s critical to check that records from the source system were properly transferred as part of the migration processData Verification Service.
Small mistakes in data preparation for transfer can occasionally lead to major issues. If a key field in the customer master record is erroneously allocated (for example, if a range of cells in a spreadsheet was mistakenly pushed up or down when the data was being produced), shipping addresses or outstanding bills may be assigned to the incorrect customer.
As a result, it’s critical to double-check that the data in the destination system matches the data in the source systemData Verification Service. This may be done manually by sampling data from both the source and destination systems to ensure accuracy, or it can be done automatically by running a comprehensive verification of the imported data, matching all records, and identifying any exceptions.

Data Verification Service is a continuous procedure.
Data transfer isn’t the only thing that requires verification. It’s also crucial for maintaining the accuracy and consistency of company data throughout time.Consider the following scenario: you have a database of customers who have purchased your productData Verification Service, and you want to send them a promotional offer for a new accessory for that product. Because some of the client information may be outdated, it’s a good idea to double-check the data before sending out your mailing.
You can detect customer records with outdated addresses by comparing customer addresses to the postal service’s change of address database. You may even update client information as part of the procedure in many circumstances.
Another crucial Data Verification Serviceis finding duplicate records. If the same client appears three or four times in your customer database, you’re likely to send them multiple mailings. This not only costs you extra money, but it also gives your customers a bad impression of you.
Multiple entries for the same client may have been produced using slightly different variants on a person’s name, making the deduplication procedure more difficult. The procedure can be improved by using tools that employ fuzzy logic to discover probable and likely matchesData Verification Service.
The need for Data Verification Service
More and more corporate executives are seeing the strategic worth of data in the insights that artificial intelligence/machine learning and current business intelligence technologies can derive from it.Regrettably, the adage “trash in, rubbish out” holds now more than ever. As the volume of data grows, data-driven businesses must implement proactive strategies to monitor and maintain data quality regularly. Otherwise, they run the danger of acting on insights based on faulty Data Verification Service.
