As your data operations evolve, they become messier.
Diverse data sources and data models at their sources, multiple movements of data throughout your platform, and cobbled-up infrastructure, which has grown in complexity through every deployment have made it hard to identify, trace, classify, and understand your data assets.
This can be as simple as an analyst spending hours trying to figure out where a data attribute in a table came from and whether it is trustworthy.
But it can also be as complex as a multi-month migration to the cloud, which is constantly delayed by trying to figure out whether a data pipeline should be moved, refactored, or simply dropped. Taxing your developers and prolonging your digital transformation due date.
And the issues scale with the growth of data your organization processes.
Metadata management and a good metadata strategy can become invaluable allies within your enterprise architecture to combat the entropy of evolving data operations.
Simply put, metadata is “data about data”. It gives the context of who, what, where, why, when, and how interacted with the data.
A good data platform will automatically generate metadata alongside its main processes. During the ETL process, the core data is augmented with metadata captured at all operational processes. Aka during:
Metadata provides the context of who, what, where, why, when, and how. This information is crucial for establishing metadata management.
A properly configured metadata system helps us answer important questions:
The questions asked bridge the different types of metadata: business metadata used to drive data governance and understanding, and technical metadata (also called operational metadata), used to drive engineering efficiency.
Let’s dive deeper into the world of metadata management.
Metadata management refers to the system of administering metadata. That is, taking care of its production, capture, systematization, and ultimately use throughout the enterprise.
Several stakeholders have skin in the game with metadata management:
Let’s look at the benefits of metadata management within an organization.
Metadata management is the driver behind the crucial data capabilities of modern enterprises.
Governance processes encompass all high-level decision processes surrounding data management. From establishing data lineage to securing data quality and accessibility, data governance establishes a set of rules and best practices for driving data standards within an organization.
A metadata management system unlocks the potential to both build policies around metadata (e.g. establish who has access to certain data assets), as well as verify whether the governance processes being set in place are being adhered to.
Regulatory compliance - as required by GDPR, HIPAA, PII, BCBS, or CCPA - legislates the allowed use of data and imposes certain standards surrounding sensitive data (such as personally identifiable information, PII).
Metadata management allows you to both control and retroactively inspect data assets for compliance. For example, if a customer requests all their data (as allowed by GDPR), the metadata management system allows you to quickly trace data throughout your organization and reply to the customer faster and without wasting time tracing data through your ETL pipelines.
The data catalog, or data dictionary, is a business glossary containing the business definitions surrounding data.
For example, how do you define a new customer? In a subscription model, where a customer churned and later returned, does that count towards a new customer, or an existing one?
Data catalogs bring clarity of interpretation and disambiguate potentially wrong analyses of data.
Understanding where data comes from (data provenance) and how it moves throughout the workflows in your system is crucial for multiple features: from tracing (regulatory compliance), to root cause analysis (more below).
Metadata management allows you to follow the data lineage of assets throughout your system.
Data lineage is leveraged for error resolution via Root Cause Analysis (RCA). Consulting the mappings of the data journey helps you trace the error down the pathway to its source and remove the error. This speeds up error resolution as well as improves the data quality.
Understanding the business context of your data (data catalog), where it came from (data lineage), resolving the issues surrounding your data (root cause analysis), and constantly monitoring metadata for outliers and unexpected patterns allows you to increase data quality and build trust throughout the system.
Metadata management systems offer you faster time to insights. A common bottleneck of analytics is trying to understand the data analysts are working with, leading to slower analysis delivery.
This fosters greater collaboration between departments (the analyst can inspect the metadata to determine the owner of a workflow that produced the data) and shortcuts the time to understanding data (for example, by inspecting its origins or the data catalogs).
All together, faster insights also bring quicker project delivery, faster iterations, that both drive company growth as well as liberate the analysts’ time for more revenue-generating work.
