What is extracting data from a database?

Accurate data is the key to business success, and today it can come from more sources than ever. Your organization might have data stored in databases, coming from SaaS, or held at IoT devices. So how do you bring all that data together so it becomes useful for you?

The first step is data extraction. What is data extraction? Data extraction obtains the data from these sources, allowing you to consolidate your data and prepare it for analysis via one of the many available Business Intelligence (BI) tools or analytics platforms.

Proper data extraction retrieves and collates data from sources of varying types. Data may be unstructured or structured, highly organized, or not organized at all. At this stage of the data consolidation process, all that matters is that a thorough extraction of data takes place.

Why is Data Extraction Vital?

Data extraction is the critical first step in the ETL process. ETL stands for Extract, Transform, Load. It involves gathering, restructuring, and storing all your organization’s data in one place where you can access, analyze and use it effectively.

For data to be useable, it has to be accurate, and it has to be complete. Think about trying to assess how effective a particular marketing campaign was over a certain period. You would probably use a service like Salesforce or your own in-house sales monitoring software to assess actual sales or client interactions. But other useful information could include:

  • Social media interaction
  • How many people clicked through online adverts
  • Emails, SMS, or phone calls received
  • Hits on relevant blogs or web pages
  • Which parts of the website people interacted with the most

Knowing what works allows you to focus on replicating that or improving on that for future campaigns. That’s why being able to extract the data from all these sources is vital. It gives you an accurate picture of how customers, clients, or users are interacting with your organization, products, or services.

Data Extraction Types

Extracting raw data without an ETL tool or other data integration solution is a fraught process — how are you going to store all that data once you’ve extracted it? It’s far more common to extract data as part of an overall process, usually either ETL or ELT. The latter stands for Extract, Load, Transfer.

You can extract the information in full from individual sources, incrementally as needed, or based on updates from the data sources themselves.

Full Data Extraction

When you set up a data pipeline to a data source, you may have to run a full extraction the very first time you do this. This ensures the data pipeline, the route between the data source and destination, works correctly and that the data source is communicating with your data warehouse or ETL tool.

Another reason full extraction may occur is that there is no way to identify changes. Or, the system could know a change has occurred but not be able to identify the exact record or data point where the change occurred, so it has no choice but to update all the data.

Incremental Data Extraction

Once a data pipeline has been established, some data sources may recognize exactly which records have updated or altered and change only those points within your data warehouse. This would extract just those new records, which is less of a drain on resources.

Notification-Based Data Extraction

In an ideal world, all data sources would provide a notification every time data changes. Some sources do this, allowing an automated extraction tool to respond and keep the data warehouse as up-to-date as possible.

During the extraction process, your extraction tool should check for changes to the structure of the data, retrieve those changed tables or records and extract them ready to replicate to your destination.

Some extraction tools use SQL to extract data from a database but will normally use APIs to connect to SaaS. That’s why it’s important to make sure your ETL tool supports the right integrations and connections. You need to be confident that you can create effective data pipelines for your organization.

Why is It Important?

Data extraction is important because it can be used to extract data from any kind of text. This is especially useful for social media content or any other form of textual data that has been shared on the internet.

There are many reasons why it is important, including:

– Extracting information from texts that contain a lot of information and are too long to read fully.

– Extracting information from texts that have been published on the internet in formats like PDFs, webpages, word documents, PDFs or any other type of format.

– Extracting information from texts that have been published in languages that we do not understand and need to translate them into our native language.

How do you extract data?

There are many ways to extract data. For example, extracting a list of contacts from an email, extracting information from a webpage, extracting financial data from accounting records, or extracting data from PDF documents.


There are two types of data extraction: manual and automated. Manual data extraction is a process in which data is manually collected from sources. Automated data extraction is a process in which data is collected from sources using software or other automated means.

What are the Challenges of Data Extraction?

The challenges of data extraction include the cost and time required to extract data, as well as the accuracy of the data. Data extraction can be a costly and time-consuming process, and the accuracy of the data depends on the quality of the data source.

It is the first step in managing the full lifecycle of data and should be handled with care.

The following are some of the challenges that can be faced while extracting data:

1. Data quality

Data quality is one of the most important aspects in analytics. Many companies extract data from different sources to get a richer, more accurate picture of what is happening in their business, but this can come at a cost. The benefits of extracting data from multiple sources might not outweigh the risks that come with poor data quality.

This is considered one of the top data extraction challenges that organizations are facing in this digital age.

2. Lack of standardization

Information is everywhere, but it’s not always in the format you need. Most companies store their information in a way that only they can read, which means that you’ll need to use their software. This can be costly and time-consuming when you’re looking for information from different sources and they don’t conform to your needs or expectations.

3. Lack of access

Finding the right data can be a daunting and costly process. There are many reasons why you might not be able to easily extract data from a source. One reason could be that the sources don’t have the required data or it is hidden behind a high paywall.

4. Incomplete data

The data extraction process is not always perfect. Some data may be missing due to errors or omissions during the extraction process.

What are the Benefits of Data Extraction?

There are many benefits of data extraction, including the ability to:

1- Easily access data

One of the most important data extraction benefits is the ability to easily access data that is stored in a variety of formats to make it easier to review and analyze. Often times, transformations are needed in order to make data that is stored in formats such as PDFs and text files ready for analysis.

2- Improve accuracy

Data entry errors can jeopardize accuracy and in research, these errors can lead to costly mistakes. It is important to reduce human error by using software that extracts data more accurately than humans and reduces the risk of mistakes.

3- Improve productivity

Data extraction makes it possible to automatically extract data from various sources and export it into a spreadsheet or database. This can be beneficial when attempting to enter large quantities of data.

Automated extraction of data is one of the top benefits of data extraction which will lead to higher productivity.

4- Enhance customer service


It can enhance customer service by providing accurate and timely information that can be used to resolve customer inquiries and complaints. Additionally, data extraction can help identify trends and issues that may be affecting customer satisfaction.

5- Help automate processes

Automation can free up time and resources that can be used to improve other areas of the business. Additionally, it can help transform business processes into a fully digital and automated ones.

6- Informed decisions making

Perhaps the most obvious benefit of data extraction is that it can help businesses to make better decisions. Data can provide insight into customer behavior, trends, and preferences. This information can be used to make strategic decisions about pricing, product development, and marketing

7- Improve competitive position

Finally, It can help businesses to improve their competitive position. By understanding the data that their competitors are collecting, businesses can develop strategies to gain a competitive edge.

Some Examples of Data Extraction

There are many examples of data extraction, but some common ones include extracting data from a database, extracting data from a web page, and extracting data from a document.

The 3 examples are web scrapping, data mining, and data warehousing.

1- Web Scrapping


Web scraping is the process of extracting data from websites. It is a form of data mining, and can be used to collect data from sources that are otherwise difficult or impossible to obtain. Web scraping can be used to gather pricing information, contact information, product information, and much more.

It is essential for data-driven businesses, and can be used to make informed decisions about pricing, product development, and marketing.

2- Data Mining

Data mining is the process of extracting useful information from large data sets. It is important because it allows businesses to make better decisions by understanding their customers and their data.

3- Data Warehousing


Data warehousing is a type of database used for storing data from multiple sources. Data warehouses are important because they allow businesses to consolidate data from multiple sources into one central location. This makes it easier to access and analyze data, and it also makes it easier to share data with other applications.
