Structured Vs. Unstructured Data: What Is the Difference?

Data analysts need to be able distinguish between different types of data. There are two types of big data: structured or unstructured. In an ideal world, data should be organized in tables, columns, and rows. They should be neatly stored in a warehouse, relational database. This information can be used to extract useful information. In reality, however, data rarely starts in this manner. Unstructured raw data can result in a torrent of unstructured information stored in large, disorganized repositories known as data lakes. This type of data will be difficult for traditional analytics. Before you can draw insights, your data must first be organized and coherent. After this, you can start targeted activities like data mining (identifying patterns and testing hypotheses) or data predictive analysis (testing them).

What Is the Difference Between Qualitative and Quantitative Data?

Before we can appreciate the differences between structured and unstructured data, it is essential to first understand qualitative and quantitative data. This topic is covered in detail in our blog post. Here’s a summary: Quantitative data refers to quantities. They can be measured or given numerical values. Quantitative data can be used to display dates, times, and weights. Qualitative data, however, are mainly descriptive. These data can be observed but not necessarily measured. These data include blood types, brand names and car brands, product reviews and names, eye colors and even eye color. While qualitative data may contain numerical values, these are usually descriptors or classifiers that do not follow any established measurement scale. See ordinal data for more information. These definitions do not have to be complex. Knowing the difference between quantitative and qualitative data will help you differentiate between structured and unstructured data. This will be apparent as we go on.

What Is Structured Data?

Structured data is data that can fit within a predefined structure. It’s a predefined data structure that defines data types and rules to access and process those data. Any clearly labeled information database, such as an Excel file, SQL database, or data warehouse can contain structured data. These data are stored in tables that have clear relationships between rows and columns. This data is easy to analyse and mine. SQL (Structured Query Language), is a popular tool for this purpose. Because structured data is well documented, it can be easily sorted out and labeled. Let’s say you have a customer email campaign. Your customer relationship management (CRM) may contain a lot of customer information, including phone numbers, invoices and history of interactions.
