With businesses today managing vast volumes of data spread across various databases, cloud services, and Internet of Things (IoT) devices, keeping track of everything is becoming increasingly challenging. This also makes it tough for data teams to track down the information they need and make sense of it all.

That’s where data catalogs help. Unlike in the past, when data catalogs needed custom scripts to search for and gather information, today's systems are much more advanced. They can automatically detect and organize data properties and profiles, making life a lot easier.

Stick around to discover how data catalogs can transform your data management and get a closer look at 10 leading data catalog tools. 

What is a data catalog tool?

A data catalog is an organized inventory of metadata that helps businesses manage and find their data assets more efficiently. It serves as a central repository where all available data within an organization is listed, described, and categorized. 

By providing metadata—information about the data itself—a data catalog tool helps users understand the context, source, and usage of data, making it easier to access and analyze.

Catalogs use metadata to enable data professionals to collect, organize, access, and enrich metadata to support data discovery and governance.

Key features of a data catalog tool

The key features of a data catalog tool include:

1. Data Integration and Discovery: The ability to connect to various data sources and automatically discover metadata from systems, applications, databases, files, and external APIs. Continuous data discovery is essential to keep the catalog up to date.

2. Search and Find Functionality: A data catalog should provide robust search capabilities, allowing users to find and access relevant data efficiently. This includes full-text search powered by Artificial Intelligence (AI) and Large Language Models (LLMs).

3. Metadata Management & Templates: Good data catalogs allow adding custom metadata and tagging data with information, such as data categories, business owners, and other important details.

4. Data Lineage: Data lineage helps users understand the origin and destination of any data asset in a data catalog. It is essential to meet regulatory requirements for the traceability of calculations and data preparation.

5. Business Glossary: A business glossary is crucial for linking technical metadata to business terms, providing a common understanding of the organization's data assets.

6. AI and Machine Learning: Many modern data catalogs use AI and machine learning algorithms for metadata harvesting, cataloging, tagging, and automated search recommendations.

7. Collaboration Features: Collaboration tools, such as the ability to rate a dataset, comment on it, share it with coworkers, and other social features are important for user adoption.

8. User Access Controls: The catalog tool should allow you to set granular role-based access controls (RBAC) to ensure data governance.

9. Automation: Automation through AI ensures that the catalog is always up to date, as manual maintenance can lead to obsolete data and decreased user adoption.

10. User Experience (UX): The catalog should be designed and accessible for users of all technical backgrounds, with advanced features reserved for technical users, such as data stewards and engineers. Usability is a key factor for long-term user adoption across the business.

11. Data Monitoring and Observability: Rather than having a separate tool and creating additional costs and platforms to manage, choose a tool that provides more than just data cataloging. The most comprehensive tools integrate data monitoring into the catalog to give you visibility into the health of your entire stack in one place.

Why are data catalog tools useful?

Effective data catalogs are more than just a repository of definitions and assets. For data catalogs to be valuable, they need to be user-friendly for both technical and non-technical users.

Data catalog tools are useful for several reasons, including improved data efficiency and analysis. 

Here are some key benefits of using a data catalog tool:

• Improved Data Efficiency: Data catalogs make it easier to find data, avoid duplication, understand data better, ensure data rules are followed, make data integration smoother, and encourage teamwork.

• Enhanced Data Context: Data catalogs provide detailed information about datasets, including their origin, quality, usage, and connections to other datasets. This information makes it easier for users to understand the meaning, importance, and suitability of the data, leading to better decision-making and analysis.

• Streamlined Data Access: A well-designed data catalog makes it easier for users to find the right datasets and build and launch new use cases. It also helps quickly identify areas for improvement in their data management strategy.

• Improved Data Analysis: Data catalogs improve data analysis by making it easier to find data, offering context with metadata, ensuring data quality, and enabling teamwork.

• Increased User Trust: By providing important information about each dataset, data catalogs help ensure that users have the correct data for their applications, thus increasing user trust

Overall, data catalogs play an important role in enabling organizations to make better use of their data and drive insights that can help inform business decisions.

How to choose the right data catalog tool for your company

When evaluating a data catalog tool, there are several factors you should consider. Here are some steps to take to choose the best tool for your business:

• Consider Your Needs — First, it can be helpful to clearly outline the needs and goals of your business and what you expect from your data catalog tool to help you achieve these goals. Talking to your data team and other decision stakeholders can help you outline these goals. Once you have your goals in mind, it will be easier to narrow down the selection of potential tools.
• Compare Tools — Next, you can compare the different data catalog tools. Take a look at the different features and see how they can help you reach your data goals. See if the tools have capabilities outside of data cataloging and if those features are important to you. You should also keep your budget in mind, as the price of each tool can vary.
• Seek Feedback — Once you’ve lined up a few options, it’s good to seek some second opinions. Talk to your data team and other team members to get feedback about each of your options. This could help you narrow down your options even more before you start trying tools out. It’s also a good idea to ask peers in your industry about their experience with data catalog tools and if they have any recommendations.
• Demo Your Tool — Now you’re ready to give the tools you’ve selected a trial run. Most companies offer free trials or demos to show you how their tool could help your organization. Make sure your team members can test these tools too. This allows you to get a comprehensive picture of each option and see if your team has any favorites. 

Choosing the right data catalog tool is important, so make sure to weigh your needs and goals when making your decision.
