For the past several years we have been subjected to various analogies invoked to convey the growth in data we are experiencing – from avalanche to tsunami, oddly all related to natural disasters. While we are getting jaded by these tropes, the underlying problem, however, is real. The data we have access to as part of our organizations is growing exponentially in volume and complexity, and the effort to harness it to propel digital transformation initiatives is increasing rapidly. But even at the granular level, understanding data can be difficult. Consider a single attribute like Gender, which can have multiple values across data sets. Some data sets containing Gender may have 3 values, some 5, and others 10. Metadata helps explain these variations across data sets and brings awareness to the data as a whole. Digital transformation requires us to understand data and use it innovatively and efficiently; the key component that can help in improving the efficiency of such data-driven initiatives is active metadata.
These days, while we are seeing an increased interest in metadata it is still mostly an afterthought or worse, the untapped effluent of a data management implementation. However, active metadata is a vital foundation and semantic layer of a well-architected data management system, which yields surprising benefits across the lifecycle of data projects. Metadata provides a means to understand all the information available in an enterprise, its quality, and relevance. Metadata’s value grows even more if it is active - overlaid with machine learning , augmented with human knowledge, and integrated. It makes the wider data management processes intelligent and dynamic. As an example, metadata can highlight missing, incorrect, or anomalous data. It can then help improve the quality of analytics where the data behind a report is automatically corrected and enriched to improve decision making and avoid costly mistakes. (Metadata management is an essential part of a System Thinking approach to data. To learn more, read this blog post about System Thinking for data and why it’s so important for data leaders.)
To maximize the benefits of a metadata foundation we need to tap into four major categories of metadata:
The process to bring metadata across these four categories together into a common and shared metadata layer should include these 3 steps:
By gathering technical, business, operational and usage metadata we create a knowledge graph of an enterprise’s data assets with their relationships. This metadata graph is made active when you apply AI and machine learning and integrate it with data management solutions. Active metadata makes it easier, efficient, and automated for users to build, deploy, and operate data management applications for analytics, data science, governance, or almost any other purpose.
A great way to achieve active metadata is by implementing an enterprise data catalog and ensuring it is integrated into your data processes. In fact, analyst firm Gartner advises its clients to “Favor providers of data integration tools that exhibit a clear roadmap showing how active metadata-driven ML enables better business outcomes or service levels.”[1]
Consider the benefits active metadata provides:
Data is considered the currency of business driving all digital transformation. An intelligent metadata layer, constructed, inferred, enriched, provides both deep insight into your rapidly growing data as well as maximizes the use and value of this data. Active metadata is indispensable for developing secure, efficient, and elegant data applications taking full advantage of the vast amount of data that is now available to business.
