As organizations continue to accumulate vast amounts of data, managing and organizing that data becomes a critical task. Two important concepts that can help in this effort are data taxonomy and data versioning with dimensions. Data taxonomy refers to the process of classifying data based on its characteristics and properties, while data versioning with dimensions involves keeping track of changes to the data over time by identifying different versions of the data based on various dimensions. In this post, we will dive deeper into these concepts and explore their benefits for data management and analysis.

What is Data Taxonomy?
Data taxonomy is the process of classifying data based on its characteristics and properties. By creating a taxonomy, data can be organized and accessed more easily, and its value can be better understood. There are several different types of data taxonomy, including hierarchical and faceted taxonomy.
Hierarchical taxonomy involves organizing data into a hierarchical structure, with broad categories at the top and increasingly specific subcategories below. This approach is useful for organizing data that fits neatly into predefined categories. For example, a retail company might use a hierarchical taxonomy to classify products by department, category, and subcategory.
Faceted taxonomy involves organizing data into multiple facets or dimensions, allowing for more flexible and dynamic classification. Faceted taxonomy is useful when data can be classified in multiple ways, and when users need to filter and search for data based on different criteria. For example, a real estate company might use a faceted taxonomy to classify properties by location, price, size, and features.
What is Data Versioning with Dimensions?
Data versioning with dimensions involves keeping track of changes to the data over time by identifying different versions of the data based on various dimensions. This allows organizations to maintain a historical record of the data, and to track changes and updates to the data over time. By using different dimensions, such as time, location, and data source, organizations can identify and analyze different versions of the data.
For example, suppose a healthcare organization collects data on patient health outcomes over time. By versioning the data based on time, the organization can analyze changes in outcomes over time and identify trends and patterns. By versioning the data based on location, the organization can analyze differences in outcomes between different regions or facilities.
Best Practices for Data Taxonomy and Data Versioning with Dimensions
To create a robust data taxonomy, organizations should engage stakeholders from different departments and functions to ensure that the taxonomy is comprehensive and reflects the needs of different users. The taxonomy should be regularly reviewed and refined as new data is added or as business needs change.
To implement data versioning with dimensions, organizations should establish clear version control policies and procedures, including guidelines for when and how data should be versioned, and who is responsible for managing the versions. Organizations should also establish a data governance framework to ensure that data is consistent, accurate, and of high quality.
How Data Taxonomy and Data Versioning with Dimensions Supports Data Analysis and AI
Having a clear data taxonomy and versioning strategy can support data analysis and machine learning efforts. By classifying data based on its characteristics and properties, and by tracking changes to the data over time, organizations can ensure data consistency, quality, and accuracy. This is especially important for effective AI and machine learning training, as the accuracy of the resulting models depends on the quality and consistency of the input data.
Data taxonomy and data versioning with dimensions are essential tools for managing and organizing large amounts of data, it will be part of building a data strategy. By classifying data based on its characteristics and properties and keeping track of changes to the data over time using various dimensions, organizations can ensure data consistency, quality, and accuracy. Additionally, having a clear data taxonomy and version will help us in a comprehensive data audit.
