Business Glossary vs Data Catalog

Both "Business Glossary" and "Data Catalog" are important components of a modern data governance framework. They serve distinct purposes and provide unique value to organizations aiming to improve their data management practices. Here's a comparison of the two:

Understanding the Basics

While you may think the terms "Business Glossary" and "Data Catalog" refer to the same thing, they are separate systems with unique purposes and functionalities. Let’s start with the basics.

What is a Business Glossary?

A business glossary, also referred to as a data glossary, is a comprehensive collection of terms, definitions, and explanations specific to a particular organization or industry. It serves as a reference guide for employees and stakeholders to understand the terminology used within the business context.

Because it is sometimes called a data glossary, it is often confused with a data catalog or a data dictionary. It is, however, its own tool and an important one for any company to have in place.

The main purpose of a business glossary is to promote a common understanding of key terms and concepts across different departments and roles within an organization. It helps to eliminate confusion, improve communication, and ensure consistency in the usage of business terms.

A business glossary typically includes definitions for industry-specific jargon, acronyms, abbreviations, and technical terms relevant to the organization's operations. It may also provide additional information such as related terms, synonyms, usage examples, and references to relevant documents or data sources.

A business glossary is typically created by data management teams. These teams are responsible for defining and maintaining a common set of business terms and ensuring consistency in their usage across the organization. The team may consist of data stewards, subject matter experts, business analysts, and other individuals who have expertise in the specific domain or industry.

The creation of a business glossary is an ongoing effort, as new terms emerge or existing terms evolve over time. The team responsible for the glossary regularly updates and maintains it to reflect changes in the business environment and to accommodate new terminology requirements.

Having a well-maintained business glossary offers several benefits. It enhances collaboration, especially when working across different teams or departments. It facilitates effective communication between business and technical stakeholders. It also aids in onboarding new employees by providing a centralized resource for learning the language of the business.

How to Structure a Business Glossary

To initiate the organization of your business glossary, consider structuring it in three hierarchical layers:

1. Term: The basic building block of a business glossary. This could be a definition of a metric, its computation formula, or a specific business classification.
2. Category: Terms are clustered into categories, reflecting their business application, ensuring improved contextual understanding and systematic arrangement.
3. Glossary: Categories are then assembled into glossaries. Envision a business glossary as a collection of several sub-glossaries, each pertaining to distinct teams, business sectors, or data origins.

What is a Data Catalog?

A data catalog is a centralized repository that organizes and provides detailed information about the data assets within an organization. It serves as a comprehensive catalog or index of all available data sources, datasets, databases, files, and other data-related resources. Here’s how Gartner puts it:

A data catalog creates and maintains an inventory of data assets through the discovery, description and organization of distributed datasets. The data catalog provides context to enable data stewards, data/business analysts, data engineers, data scientists and other line of business (LOB) data consumers to find and understand relevant datasets for the purpose of extracting business value.

The primary purpose of a data catalog is to help data users, analysts, data scientists, and other stakeholders discover, understand, and access the data assets they need for their work. It provides a searchable and user-friendly interface that allows users to explore the available data resources, understand their structure, content, and relationships, and determine their relevance and suitability for specific use cases.

A typical data catalog includes various metadata, such as data descriptions, schema, structure, lineage, permissions, usage, and data governance information.  

Similar to the business glossary, a data catalog is typically created and managed by data teams, including data stewards, architects, analysts, and subject matter experts. Maintaining a data catalog is an ongoing effort, as new data is constantly being captured. Companies need timely and accurate data in order to stay ahead of trends and make data-driven decisions.

By providing a centralized and easily accessible inventory of data assets, a data catalog helps to improve data discoverability, eliminate data silos, foster data collaboration, and enhance data governance and compliance. It enables organizations to make more informed decisions, accelerate data-driven initiatives, and maximize the value of their data assets.

The Key Differences Between a Business Glossary and a Data Catalog

The main difference between a business glossary and a data catalog is that a business glossary focuses on the common understanding of business terminology and concepts, while a data catalog provides a comprehensive inventory of data assets.

Imagine you're in a foreign country trying to communicate with locals. A business glossary is like a translation app that helps you understand and use the local language effectively. It provides definitions and explanations for specific words and phrases used in that country. It helps you avoid embarrassing misunderstandings and miscommunication.

Now, think of a data catalog as a map or guidebook that helps you navigate the city. It lists all the important places, such as landmarks, restaurants, and shops, along with detailed information like addresses, opening hours, and descriptions. It would be easy to get lost without this information.

You wouldn’t want to be in a foreign country without a translating tool or a map (or access to these on your phone, we should say!). While a business glossary helps you speak the language of the business effectively, a data catalog helps you navigate and find the data you need for your work.

Purpose and Functionality

In addition to differences in their content, business glossaries and data catalogs differ in their purpose and functionality.

The main purpose of a data catalog is to facilitate data discovery, understanding, and access. It serves as a comprehensive inventory and metadata repository of data assets, providing detailed information about the data structure, content, quality, permissions, lineage, and usage examples. The data catalog helps data users and analysts find relevant data resources for their analysis, reporting, or other data-related tasks.

1. Dataset Exploration: Advanced search functionalities encompass facet-based searches, keyword queries, and business term lookups. The inclusion of natural language search is particularly beneficial for those without a technical background. The ability to rank search outcomes based on relevance and usage frequency stands out as especially advantageous.
2. Dataset Assessment: To select the most fitting datasets, users must gauge their appropriateness for specific analytical scenarios without the preliminary need to download or procure the data. Key assessment tools comprise dataset previews, comprehensive metadata viewing, user-generated ratings and reviews, curator notes, and insights into data quality.
3. Data Retrieval: Transitioning from dataset exploration to assessment and ultimately to data retrieval should be an uninterrupted journey. The catalog should be adept at recognizing access protocols, either granting direct access or collaborating with other access technologies. Crucial data retrieval features encompass safeguards for data that is sensitive in terms of security, privacy, and regulatory compliance.

The primary purpose of a business glossary is to establish a common understanding of business terminology, jargon, and concepts within an organization. It aims to promote effective communication and collaboration by providing clear definitions, explanations, and additional information about business terms and industry-specific concepts.

Users and Beneficiaries

There are also key differences in the intended audience for each tool. 

A business glossary targets all employees and stakeholders who need to understand and use consistent business terminology. It facilitates communication and collaboration within the organization. 

Think about your first day at your company. You were probably inundated with various acronyms and company-specific jargon that made you feel like you were lost in unfamiliar territory without a guide. Fortunately, a business glossary comes to the rescue, aiding everyone in comprehending those perplexing acronyms and business jargon that organizations often curiously cherish.

On the other hand, a data catalog caters to data users and analysts who require a comprehensive view of available data assets. It aids in data discovery, understanding, and access for effective data-driven decision-making. While early data catalogs were built primarily for data teams, today’s modern data catalogs cater to the whole company.

Making data-driven decisions has become increasingly important in today’s competitive landscape, which is why CastorDoc appeals to users across an organization, including both data people and business teams. Data teams diligently maintain and manage the organization's valuable data, ensuring its accuracy and reliability. Business leadership enjoys effortless access to the data they require, enabling them to make informed decisions that drive the company's success.

Business Glossary & Data Catalog are meant to work together

Business Glossary and Data Catalog are important components of the data governance framework. They serve distinct purposes, yet, they are intrinsically linked and are meant to work together to provide a comprehensive understanding of an organization's data landscape. Here're a few reasons why they are complementary and should be integrated:

• Business Glossary provides definitions: This provides context, and business relevance for terms and metrics. It's the "what" and "why" of data. It helps stakeholders understand data's business meaning.
• Data Catalog provides localization: This is about the "where" and "how" of data. It identifies where data resides, its source, its transformation, and its consumption. It's a map to the data landscape.

Data catalogs effectively utilize the context provided by a business glossary:

1. Seamless Context Integration: Top-tier data catalog tools consistently integrate business glossary context into every asset, enhancing your search experience.
2. Enhanced Search Capabilities: Contemporary data catalog tools empower users to explore data assets using specific terms of interest.
3. Empowering Collective Input: Data catalogs facilitate the crowdsourcing of context for data within a business glossary, cultivating trust among team members.
4. Eliminating Siloed Knowledge: With data catalogs, all authorized users can contribute their unique context to the business glossary. The premier tools ensure streamlined governance of these contributions, reminiscent of the approval process in shared Google documents.

Modern companies need both a business glossary AND a data catalog. It’s not an either/or. The two systems are both vital and they serve different purposes. If you had a business glossary but no data catalog, you would have a solid understanding of business terminology but would struggle to effectively locate, analyze, and utilize the data assets within your organization.

Likewise, if you had a data catalog but no business glossary, you would have a comprehensive inventory of data assets, but you might face challenges in understanding what those data assets mean. This could hinder effective communication and would likely result in poor decision-making.
