Information About Data Cleaning And Data Services

Data Cleaning Is Important for Big Data Accuracy.

Data cleaning, also known as data cleansing, is the act of correcting or removing corrupt or incorrect records from a record set or table. It involves identifying incomplete, inaccurate, inaccurate, irrelevant, or irrelevant data, and then replacing, modifying, or deleting the bad or dirty data. Data cleaning can be done interactively using data wrangling tools or batch processing via scripting and a data quality firewall.

Why Should Data Sets Be Compatible?

A data set should be compatible with all other data sets within the system after it has been cleaned. Inconsistencies that are detected or corrected may be due to user errors, corruption in transmission or storage, and/or different data dictionary definitions for similar entities in different stores.

How Does Data Validation Differ From Data Cleaning?”

Data validation is different from data cleaning in that data is almost always rejected at entry. Instead of performing batches of data, data cleaning is done at the time of entry.

Data Cleaning Includes What Actions Or Tasks?

Data cleansing can include correcting errors, validating and adjusting values against a list of known entities, or removing typographical errors. Validation can be very strict, such as rejecting addresses without a valid postcode (aka Zip Code in the U.S.). It may also include fuzzy matching or approximate string matching (such as correcting records that are only partially compatible with known records). Data cleansing solutions can be used to clean data by cross-checking it with a valid data set. Data enhancement is a common method of data cleansing. This involves making data more complete by adding relevant information. Appending addresses to any associated phone numbers is one example of data enhancement. Data cleansing can also include harmonization (or normalization of data), which is the process to bring together “various file formats, name conventions, and columns” and transform them into one cohesive data set.

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.

City of Columbus OH Information

Columbus OH

The state capital, Columbus, is also the largest city in Ohio. It is also the county seat for Franklin County. It is the heart of the Columbus metropolitan region, which includes 10 central Ohio counties.


In 1816, the city was designated as the state capital and in 1824, it became the county seat. Despite years of steady growth and industrialization the city has been through many floods and recessions. In the 1950s, Columbus experienced significant growth. It was the largest city in Ohio by land and population in the early 1990s. Many neighborhoods of the city saw redevelopment during the 1990s and 2000s, including Downtown.


The climate of the city is humid continental transitional, with the humid subtropical climate south, which has warm, humid summers and dry winters. Columbus is in USDA zone 6a. It borders on 7a in the normals chart for 1991 to 2020. The city does not experience the usual Nor’easters-type winter lows that can cause heavy snowfall. This makes the winter snowfall relatively light. The city is too far west and south for the lake-effect snow from Lake Erie, but the lakes to the north provide long periods of cloudy weather in winter.


The city had 905,748 residents and 362,626 families according to the 2020 United States Census. The city’s racial makeup was 57.4% white, 29.2% Black, African American, 0.2% Native American/Alaska Native, 5.9% Asian, and 29.2% Black. 6.3% of the city’s population was Hispanic/Latino of any race.


Broad and High Streets have been the city’s main corridors since its inception. Both of them extend beyond the limits of the city. High Street runs 13.5 miles (21.7 km) (23.4 throughout the county), while Broad Street runs 25.1 mi (40.4km) across the county.

Top Businesses

The economy of Columbus is diverse and strong. It includes education, banking, fashion and defense as well as insurance, banking and banking. According to Relocate America (a real estate research company), it was one the top 10 largest cities in the nation in 2010.
