How to Define, Classify, and Catalog Your Enterprise Data Assets

1. Definition and Classification of Data Assets

According to the China Academy of Information and Communications' "Data Asset Management Practice Whitepaper," a data asset is "data resources owned or controlled by an enterprise that can bring real or potential economic benefits." This emphasizes ownership and economic value, especially in China’s active data‑trading market.

Structured data: employee information, financial statements stored in relational databases.

Semi‑structured data: log files, XML documents with some organization.

Unstructured data: emails, scanned contracts, accounting for over 80% of enterprise data.

Another common classification is based on source and usage:

Internal data: data generated by the enterprise itself, such as sales records.

External data: data obtained from third parties, like social‑media comments.

Master data: core data describing business entities, e.g., customers or products.

Transaction data: data recording business activities, e.g., orders or payment records.

To identify valuable data assets, consider four characteristics: value (economic or intangible), controllability (whether the enterprise can manage the data), recordability (whether the data is captured in electronic or material form), and the need to prioritize high‑importance, high‑frequency data.

2. Data Asset Inventory

Traditional asset inventory counts physical assets; data asset inventory counts the data an enterprise currently possesses, helping answer:

How much data does the enterprise have?

What types of data exist?

What is the value of the data?

Where is the data stored, and where are the most valuable datasets?

Who owns the data and who is responsible?

The inventory process is divided into six stages: building data standards, data discovery, data definition, classification & grading, clarifying ownership, and creating a data asset catalog.

3. Data Asset Catalog Architecture

The catalog’s top layer aligns with business domains (e.g., R&D, marketing, HR). Below each domain are data domains representing core business processes (e.g., price management, contract management). The next layer consists of business objects (e.g., customer info, quotation data), followed by data entities (e.g., quote records) and finally data attributes that describe the smallest granularity of information.

4. How to Build a Data Asset Catalog

Create a custom catalog template, aggregate data according to the hierarchical structure, review and confirm with stakeholders, and maintain the catalog. Whenever new business processes, systems, or forms introduce data changes, the catalog must be updated promptly.

The catalog serves as a unified data‑management tool for business users, while a detailed data dictionary targets data managers and developers.

5. Value of a Data Asset Catalog

The catalog delivers four major benefits:

Unified data management : Provides a single, trustworthy source for all data assets, reducing duplication and improving data quality.

Self‑service exploration : Enables users of different roles to browse, search, and analyze data according to their needs.

Security and compliance : Applies classification, permissions, and access controls to meet regulatory requirements.

Efficient collaboration : Serves as the sole entry point for data, supporting knowledge sharing, tagging, and collaborative development.

By establishing a data asset catalog, enterprises can quickly inventory, classify, and organize scattered data, enabling a one‑stop data‑governance capability that lowers costs, reduces risk, and accelerates data‑driven decision‑making.
