What are data teams excited about?

Data dictionary tools are exciting for data teams, and for good reason. With a good data dictionary tool, data teams can more easily organize, manage and access data. By providing your data with more structure, your data teams will run into fewer errors and data integrity issues. Data dictionaries also help facilitate collaboration between teams, making data more accessible and easier to understand overall.

Data dictionary tools also help data teams ensure everyone is on the same page. They can easily find specific items in a data set and find relevant information like the relationships between data, the format of data and the usage of data. When data is organized and accessible for data teams, they don’t have to waste time sifting through siloed or irrelevant data. This gives them better insights and saves them time when fulfilling data requests. A data dictionary also makes it much easier for data teams to update data and ensure it’s consistent across databases.

Data teams are also excited about how automation is making an impact on data dictionary tools. Some tools can automate processes like editing and updating entries in data dictionaries. Automation can also make it easy for other team members outside the data team to access data requests without having to rely on the data team. Automation puts more time into the hands of your data team, allowing them to focus on more significant tasks.

Why data dictionary tools are useful

Before we dive into the biggest benefits of data dictionary tools, let’s ensure we understand what a data dictionary does. Put simply, a data dictionary is a repository of information about data. It organizes the definitions, names and attributes of data elements. By defining the meaning and purpose of data elements, a data dictionary provides consistency and improves data analysis.

Data dictionaries can collect more data than this, but this is essentially the purpose they serve. Data teams and other users can utilize the data dictionary as a reference guide and understand what data means and how it can be used. With that in mind, let’s take a look at some of the top benefits of data dictionary tools:

  • Data organization and management — Data dictionary tools are highly useful for organizing and managing data. With an organized data dictionary, it’s easier for data teams to identify patterns, quickly find the data they need and identify important relationships between data.
  • Streamline data-driven insights — Since data dictionaries provide easy and quick access to important information and details about data, it streamlines the process of obtaining data-driven insights. 
  • Data consistency and accuracy — One of the most prominent benefits of data dictionaries is how they help ensure data integrity. With a data dictionary, companies can ensure their data is more consistent and accurate. Defining data across teams causes less confusion and improves the quality of data. Since data dictionaries help to solve the data silo issue, it allows teams to ensure the data they’re using is accurate and reliable. Standardizing data with a data dictionary will always be helpful and beneficial for businesses.
  • Searchable data — Data dictionaries help to make data more searchable and usable. When everyone understands the context of your company data, it’s easier for all team members to use. Data dictionary tools also let data teams keep track of data changes over time, allowing them to track down issues and inconsistencies more easily.

These are just some of the biggest benefits of data dictionaries. They’re a useful tool for any modern data stack.

How to choose the right data dictionary tool for your company

Choosing a data dictionary tool is a critical decision, so make sure to take your time. Rushing a decision that can impact your organization is never a good decision. When you’re choosing your data dictionary tool, follow these steps to get the right one:

  1. Consider Your Needs — First things first, you need to consider what you want your data dictionary tool to do for your company. Think about what features matter for your business and begin by selecting the tools that can meet those needs before you start comparing. It’s also a good idea to consult your data team and others who will be using the tool.
  2. Compare the Tools — Next, you’ll need to compare the tools that are full-featured and able to integrate with your stack. There are several factors to consider during this step. Security will be paramount, as you’ll want to ensure these tools keep your data safe and encrypted. You’ll also want to ensure the tool you use is flexible and scalable. Ease of use will be another important factor, as you want to ensure your team can start using the tool as soon as possible. Finally, make sure the tool can integrate with the other data tools you use.
  3. Compare Costs — You will always need to factor your budget into your decision. Most tools will have price tiers, so you’ll need to look into these details and determine how much your company will need to pay to use these tools.
  4. Try the Tools Out — Once you’ve narrowed down your selection to a few tools, you can give them a try for yourself. Most tools will offer a free trial or a demo to give you an idea of how the tool can help your organization. Make sure you involve key team members in this process so you can determine if the tool is something that everyone wants to use and finds useful.
