Information About Data Cleaning And Data Services

Relational vs. Non-relational Databases

After we’ve discussed the basics of a relational database and its structure, you may be able to identify the main differences between non-relational and relational databases. It all comes down to how we organize the stored data.

Structured non-relational databases cannot be created. This format allows you to add any data to your database without having to create a schema. They can even be totally unrelated! You can add text and images to documents. There are no limitations on the data types that can be added. NoSQL databases, for example, do not require a schema and store data in a single type of data structure, most commonly JSON. You can have a variety of non-relational database types, including ones that support dictionary-like key-values and documents.

It is possible to wonder when users may prefer a non-relational data base. These are generally reasons for users not liking relational databases. Non-relational databases are faster because they are unstructured. This is important when data retrieval must be optimized, such as when we need to create analytical reports often.

Non-relational databases can also be useful when it is not clear what type of data you will need or how the data will change over time. Because we don’t have to create a schema, we can make changes as needed.

What Is the Use of SQL in Relational Database Management Systems?

SQL is often mentioned with databases, you might have noticed. SQL queries are a great way for technical and non-technical users to easily transform tables, merge data, and retrieve data from databases with just a few lines.

Let’s take the Shoe Company database. It has two tables: Customer and Marketing. The Customer table contains these columns: Customer ID and Mailing Address; Purchase ID and Purchased Item ID; Transaction Amount. The Marketing table contains these columns: Promotional Campaign, Customer ID, Transaction Amount, Purchase ID.

Imagine that you are an analyst assigned to determine if a back-to school sale promotional campaign had any effect on sales of shoes. This question could be approached in many different ways. One approach is to compare the amount of your top five most spending customers buying during a sale period to the period without a sale.

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.
