Information About Data Cleaning And Data Services

What Is a Relational Data Base?

Although relational databases sound intimidating, at its most basic, a database is simply a place to store information. Databases play an important role in data analytics, software engineering, data engineering, and other areas. This can look different in practice, but relational databases are a special type of database used to store and retrieve data from apps.

Because they are flexible enough to cover many industry uses, relational databases are very popular. You might be familiar with industry favorites such as SQL Server, MySQL and PostgreSQL even if you haven’t had the opportunity to use one.

What is a relational data base? You are probably familiar with Excel spreadsheets. They work in similar ways. A database can be thought of as having the same column and row structure. However, they are based on the idea of a table but have certain features that allow for data retrieval and analysis.

Multiple tables are common in databases. They can be linked together if there are overlapping columns or, in industry jargon: a primary key. Companies can use this interlinking architecture to help them make sense of the different types of data generated by their business lines.

The Relational Database Model

Let’s first look at the reasons that the relational database was created. E. F. Codd, an IBM employee, created the relational database in the 1970s. He wrote a paper outlining the rules for data storage. Each row has a unique primary key. Tables are related to each other if they have columns that correspond to the unique key. The foreign key occurs when the primary key is used in a different table.

Relational databases define the data types in each column, as well as primary keys and column names. These attributes are called the relational schema and they structure how new entries are added into a database.

This may seem too abstract. If you’re interested in analytics, it might be hard to conceptually understand why. Let’s look at an example of how businesses use them.

Let’s say you have a shoe company that sells online. They will store customer data across multiple databases depending on which data is stored when a customer orders shoes online. The columns in the Customer table could include Customer ID and Mailing Address as well as Purchase ID and Purchased Item ID. Columns in the Marketing table might include Customer ID, Transaction Amount, Purchase ID, Promotional Campaign, Purchase ID, and Purchase ID.

This simplified database shows Customer ID as the primary and foreign keys. We can now see the effect of marketing on sales generation.

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 Saint Paul MN Information

Saint Paul MN

Saint Paul, the capital of the U.S. state of Minnesota, is also the county seat for Ramsey County. Saint Paul, which is located on high bluffs with a view of the Mississippi River bend, is the heart of Minnesota’s government and a regional hub for business.


Skyscraper-building booms in downtown St. Paul began in the 1970s. All construction is subject to a height restriction because the city center is located directly below the flight path that leads to the airport across the river. Galtier Plaza (Jackson & Sibley Towers), The Pointe of Saint Paul condos and Wells Fargo Place (formerly Minnesota World Trade Center) are the tallest buildings in the city. They were built in the late 1980s.


Saint Paul enjoys a humid continental climate that is typical of the Upper Midwestern United States. Winters can be cold and snowy while summers can be hot and humid. Saint Paul is classified as a hot summer humid continental climate zone according to the Koppen climate class.


Census estimates show that the city had a population of 307,193 in 2021. This makes it the 67th largest city in the United States, 12th most populous in the Midwest and 2nd in Minnesota. The city is located east of the Mississippi River, near its confluence to the Minnesota River.


There have been many complaints about the layout of streets and roads in cities. Jesse Ventura, who was Governor of Minnesota at the time, made a comment on Late Show with David Letterman that the streets were created by “drunken Irishmen”. He later apologized for his mistake, even though many people had complained about the broken grid system for over a century. The city’s roads are a result of the Mississippi River curve, hilly topography and conflicts between developers from different neighborhoods. Grand plans were only half realized. The roads outside of downtown are more straightforward, but many roads are named rather than numbered, making it difficult for non-natives.

Top Businesses

Ecolab, a chemical- and cleaning product manufacturer, is one of the major corporations with headquarters in Saint Paul. Paul Business Journal ranked it eighth for the best place to work in the Twin Cities in 2008 for companies with over 1,000 employees. Securian Financial Group Inc. was also voted eighth.
