Types of data extraction: what you need to know

Data extraction involves extracting data from one source and converting it into another form so that it can be used in another application. In other words, data extraction helps you get data from a source and make that data readable for your own software or database. Data extraction can be manual or automated and depends on various factors, such as the data source, the attributes and properties of the data and the frequency of access. If you work in an industry where large amounts of data often need to be accessed, such as healthcare or manufacturing, then you are likely to find many applications for data extraction processes. By incorporating a form of data extraction into your business practices, you have more time and energy to focus on activities that will benefit your business in the long term.

 

How to perform data extraction?

Data extraction can be performed manually or automatically. With manual data extraction, the data is read from one source and then manually entered into another application. Manual data extraction is often used when the data volume is small and/or the structure of the data is predictable. Automatic data extraction is software-controlled and can be used when the data volume is large and/or the structure of the data is unpredictable. Automatic data extraction often uses a computer program to read the data of a source and then transfer it to a desired destination. Automatic data extraction can be performed manually or semi-automatically via an interface.

What is manual data extraction?

Manual data extraction is an offline method of extracting data from a source. Manual data extraction is used when the data volume is small, the structure of the data is predictable, and the data often needs to be extracted. In manual data extraction, a person reads the source data and then manually enters it into another application. Manual data extraction is often used for data that is not time sensitive, such as a company’s product catalog. Manual data extraction is also used when the data source is not available online. For manual data extraction, you should verify the accuracy of the data by matching the data with the source.

What is automatic data extraction?

Automatic data extraction is an online method of extracting data from a source. Automatic data extraction is used when the data volume is large or the structure of the data is unpredictable. Automatic data extraction is often used for data that is time sensitive and needs to be extracted regularly. With automatic data extraction, a computer program often reads the data from the source and transfers it to a desired destination. For example, if you work in healthcare and need to find patient records from different hospitals across the country, you can perform a data extraction that extracts the data from the electronic patient records (EMR) of each hospital and written into a single database. Automatic data extraction often uses a computer program to read the data of a source and then transfer it to a desired destination. Automatic data extraction can be performed manually or semi-automatically via an interface.

Types of automatic data extraction

– Extraction method – An extraction method is an algorithm that applies rules to a dataset and creates a new dataset that represents an extraction. – Extraction model – An extraction model is a program or set of statements used to define a data source, source attributes, and the format of the extracted data. – Source transformation – A source transformation is a process used by a computer program to read data from a source and create a new record. – Goal transformation – A goal transformation is a process used by a computer program to read a dataset and write it into a goal.

What are the benefits of data extraction?

– Improved data consistency – Using an automated data extraction tool makes it easier to monitor data consistency and track all data quality issues. This allows you to identify and correct any problems with the data before it is too late. – Less data entry errors – Using an automated data extraction tool significantly reduces the likelihood of data entry errors. This is even more true when you use an automatic data extraction tool with validation capabilities that help you identify potential data issues before the data is entered into your system. – Increased efficiency – Using an automatic data extraction tool allows you to complete tasks faster and with a smaller team. This is because employees no longer have to manually enter the data, which can be time-consuming and error-prone. – Improved data quality – If you use an automatic data extraction tool, you can easily monitor data quality. This allows you to identify and correct any problems with the data before they become a problem.

Main results

– You can perform data extraction manually or automatically. Manual data extraction takes place offline, while automatic data extraction takes place online. – Data extraction can be used to transfer data from a source to a desired destination. It can also be used to transfer data from one source to another. – Data extraction is useful to improve data consistency, reduce data entry errors and improve data quality.
