Features of Great Expectations

Superconductive, creators of Great Expectations, recently announced $40M in Series B funding for the commercial version of its open source data quality tool. It enables developers and data teams to test and validate data pipelines.

This section will discuss some of the features of this open source data quality tool and how it can enable developers and data teams to ensure data accuracy and quality.

Data Quality Assurance

Great Expectations is a platform that assists businesses in meeting the ever-increasing demand of data quality assurance. Its features ensure efficient and reliable data processing to help organisations succeed in their data-driven decision making process.

Great Expectations focuses on three key principles when it comes to data: validity, accuracy, and completeness. It offers a comprehensive set of tools for verifying that large datasets contain only valid, accurate and reliable records and that no valuable information is lost along the way. In addition, Great Expectations ensures confidence in data by providing easy access to statistical summaries, strategic diagnostics and proactive monitoring capabilities, enabling organisations to quickly identify underlying issues with their data pipelines.

In addition, Great Expectations features built-in tests for verifying accuracy such as calculating basic statistical values like mean, mode and median; checking for missing values; detecting outliers; validating column types (numeric/string/date) based on user specifications; cross-checking referential integrity by looking up columns in dictionary types etc. It also provides an alert system which notifies users when dataset thresholds or characteristics fall out of predetermined ranges or change spontaneously. This allows users to spot problems caused by incorrect assumptions or outdated patterns – these which would otherwise be hard to detect manually over large datasets.

Finally, Great Expectations supports various formats such as CSV, JSON and Parquet making it simple for all types of businesses – from small startups to large enterprises – adhere to widely accepted data quality standards without the need for costly custom implementations or vendor lock-in contracts!

Automated Data Validation

Automated data validation is an important part of the “Great Expectations” framework, which helps companies develop and manage data quality expectations and build trust in their data. Data validation is verifying the accuracy, completeness, consistency and reliability of the data being processed by software. Automated solutions quickly and efficiently check incoming data against rules based on a company’s specific requirements.

The automated processes within Great Expectations leverage machine learning techniques for efficient model training and incorporate pre-defined statistical methods to ensure consistency between datasets. This helps teams develop trust in their data without sacrificing valuable resources or adhering to laborious manual processes.

The automated validations using Great Expectations also enable audits of a company’s entire pipeline for ongoing updates on customer requirements or other changes in specifications about the format and contents of their datasets. This ensures that an organisation consistently leverages quality insights from clean, reliable customer data that meets all customer expectations.

Data Documentation

Data documentation is an important aspect of any project involving data analysis and mining. It describes creating, maintaining, and updating the data sets and elements used in a specific research. In addition, data documentation aims to ensure the accuracy and reliability of datasets used in a project so that results can be consistent throughout the entire process. This includes providing pertinent information on how to interpret the variables contained in a dataset and what processes have been used to generate them.

Data documentation should provide a clear summary of the data sources incorporated into a project, such as type (numeric or categorical) or range (if applicable). Additionally, variable definitions must be thoroughly explained to properly interpret results later. All data manipulation processes including transformation, reshaping and extracting should also be documented according to established standards to allow proper replication of study results. Further details such as notes specifying outliers or statistical assumptions might also need to be included when relevant so that each dataset is carefully annotated throughout its use. Ultimately, good documentation of data sets helps protect against discrepancies and make work more efficient for other researchers.

This article will look at the benefits of using Great Expectations.

Improved Data Quality

A key benefit of using Great Expectations is improved data quality. This enables businesses to make better decisions, as they can trust the reliability and clarity of data. In addition, organisations can leverage their existing analytics by having uniform data that’s clean and up-to-date.

Great expectations also improve the accuracy of results when used with machine learning algorithms, or any process that relies on prediction models. As many machine learning processes are based on estimation, correct dataset inputs are essential to ensure successful outcomes with reasonable confidence scores. In addition, clean data prevents costly mistakes due to erroneous conclusions from inaccurate information.

Furthermore, Great Expectations can be used for automated detection of suspicious activity in databases, ensuring an effective way to manage potential flaws or inaccuracies in datasets. By checking for correctness and completeness at an individual record level, businesses can protect their valuable resources rather than relying on end users to manually check for errors, which often introduces greater mistakes.

All these benefits manifest themselves in improved decision making capability and a reliable basis for continued improvement in machine learning accuracy. These are key businesses seeking new ways to leverage data more efficiently and achieve greater insights from their current offerings.

Increased Efficiency

Great Expectations helps to organise and centralise processes, making a company’s workflow more efficient. The software automates many tasks to save time and money, allowing staff to focus on more important elements of their job. With Great Expectations, users can manage data faster and more easily since all pertinent information is stored in one place. This eliminates the need for employees to search multiple databases for the same information.
