• A data source indicates the point of origin of a specific data set.

• You can create data sources internally through organizational processes, such as email marketing, or collect data externally through social media, depending on your business goals.

• An example of a data source is a relational database.

The two main types of data sources within big data are machine data sources and file data sources.

What is a data source?

A data source refers to the origin of a specific set of information. As businesses increasingly generate data year over year, data analysts rely on different data sources to measure business success and offer strategic recommendations. Having data literacy means you’re capable of identifying, understanding, and interpreting crucial data and its results.

Data sources play a key role by bundling information into accessible formats, which enables seamless integrations between different types of systems. This ensures that relevant information about a data set is readily available while remaining hidden, allowing analysts to focus on data interpretation and analysis. Extremely large data sets used by data analysts are called big data, and they require a framework that scales with their volume and variability.

What is an example of a data source?

Data can originate from various sources, including data warehouses, relational databases, Internet of Things (IoT) devices, Microsoft Excel spreadsheets, and web scraping tools. Source data is also known as raw or primary data.

What are the types of data sources?

Within big data, most data sources fall into two main categories, machine data sources and file data sources, based on how data is stored, accessed, and used:

• Machine data sources: Labeled by users and stored in the input machine, machine data sources are not easily shareable. The data source integrates with various components essential for accessibility, like the server location and driver engine.

• File data sources: These sources reside within single, shareable files, allowing multiple users to access and edit the data from different locations.

These data sources can be further classified into smaller categories:

• Internal data: Created by organizational processes, including email marketing, customer profiles, and online activity

• External data: Derived from outside sources like social media, historical demographic data, and websites

• Third-party analytics: Provided through analytics platforms like Google Analytics by tracking performance metrics such as page views and click-through rates

• Open data: Free, publicly accessible data, like government, health, and science data

A clear understanding of data sources is vital for effective data management. As a data analyst, you can transport the data obtained through data sources using several methods, including file transfer protocol (FTP) and hypertext transfer protocol (HTTP). In addition, you may use application programming interfaces (APIs) to enable the transfer of data sets.
