Ready to launch your career?

You can think of data modelers as being the unsung heroes of the data science process. While methods of collecting, analyzing, and interpreting data may get more attention, none of this can be done if the data isn’t organized and retrievable, and that’s exactly what data modelers do. 

If you’ve got an aptitude for organization, and are considering a career in data science, then you should definitely be considering a career in data modeling. If that sounds like you, then look no further. Our 8-step guide covers everything you need to know about a career in data modeling— from educational requirements to essential skills and average salaries—so that you can launch your career today. 

What Does a Data Modeler Do?

A data modeler is a database designer, someone who maps out the optimal way for an organization’s data to be stored. Using a variety of skills, data modelers work with stakeholders and other IT professionals to create solutions that make data easier to access, understand, and analyze. 

Is It Hard To Become a Data Modeler?

Becoming a data modeler is possible for anyone willing to put in the work.

Learn the Basics

While studying a data-related field at college is still a great option, it’s no longer the only one. Part of what makes the tech industry so accessible for new learners is the number of resources and training you can find online. 

To learn the basics, you can study independently or take introductory online courses. You can also fast-track your education with online data science bootcamps, analytics, or engineering bootcamps. With industry-leading curriculums and expert instructors, these bootcamps can take beginners to work-ready levels in under a year. 

Meet the Educational Requirements (and Continue Learning)

Most employers will want to see some form of education or certification of your skills before they employ you. If you’re not attending college, you can do this by passing industry-standard certifications or graduating from a bootcamp, and creating a professional portfolio.

The interview is where you’ll show off your skills in full and actually land the job, but you’ll still need to create a high-quality resume in order to get a job interview in the first place.

Learn Popular Data Modeling Tools

Tools are an important part of a data modeler’s skill set, and you’ll use them on every project to create conceptual, logical, and physical data models. Not everyone uses the same software, so it’s good to familiarize yourself with multiple tools so you can appeal to more employers.

Structured Query Language (SQL)

SQL skills are a must for anyone working with data, as it’s a standardized programming language that’s used to access, manage, and manipulate data in relational databases. You can use it to execute queries against a database, retrieve data, delete or insert new data, and many other tasks.

Develop and Hone the Essential Skills

Whether you’re studying independently or with an institution, a good way to develop a sense of the crucial skills you need for data modeling is to read job descriptions. This way, you can see exactly what skills and tools companies expect.

Technical Skills

Technical skills and knowledge are very important for data modelers, as you need to know both how to build data models, and how to design systems on a large scale. Technical requirements you’ll often see on job descriptions include:

  • Proficiency in relational SQL and NoSQL database technologies
  • Experience working with data modeling tools such as erwin or ER/Studio
  • A deep understanding of database management and design best practices on an enterprise level
  • Experience with and examples of conceptual, logical, and physical data modeling
  • Understanding of business intelligence concepts
  • Knowledge of metadata management and organizational data structures

Soft Skills

Data modelers work to design innovative data solutions according to an organization’s needs, and they rarely work independently. Because of this, strong collaborative, communication, and interpersonal skills are essential for the job. These include:

  • Work and communicate with business stakeholders to ensure deliverables meet business expectations 
  • Work with technical teams to deliver on commitments 
  • Collaborate with database administrators, data analysts, and data architects to build scalable solutions
  • Visualize and communicate complex data structures and concepts clearly and intuitively
  • Organizational skills
  • Experience delegating work
  • Ability to work under pressure
  • Self-motivation
  • Analytical skills

Find a Mentor

how to become a data modeler, find a mentor

Having an experienced industry professional in your network can be highly valuable at the beginning of your career. Mentors can answer all kinds of questions, anything from work-life balance questions, to technology trends and navigating the corporate hierarchy. 

You can find a mentor in various places, such as online communities, industry events, schools, and work. The relationship doesn’t need to be official. If you know an experienced data modeler or database administrator whom you can ask about various aspects of the job, then you essentially have a mentor. 

Gain Practical Experience Through an Internship

Learning how to design data solutions for large enterprises requires hands-on experience. If you don’t study projects using real data sets and business goals, it will be hard to transition into a genuine work environment. 

One of the best ways to gain experience is through an internship. These aren’t always easy to land, and not everyone has a financial situation that allows them to work for little or no compensation. But if you can swing it, an internship can definitely be worth it. 

Remember: Your Network Is Your Net Worth

Knowing people in the data modeling industry can help your new career in countless ways. From resources to internship and job opportunities, your network can assist you during every step of your journey and career. Here are some ways to do that:


Use LinkedIn to promote yourself and connect with the people you meet. Everyone benefits from expanding their network, so don’t be afraid to connect with anyone and everyone you come into contact with. 

Conferences and Meet-Ups

Showing interest and passion for the industry by attending conferences and meet-ups is a great way to both meet like-minded people and show them that you’re worth knowing. Excelling in a professional career requires you to go the extra mile, and conferences are a great way to do this in a way your colleagues can see it. 

Online Communities

Online communities are a great way to build your network when you’re just starting out. You can connect with more experienced individuals that are willing to give out advice, and learn how to ask the right questions to get noticed. 

Polish Your Resume, Start Applying for Jobs and Prepare for Each Interview

Job searching is an activity that requires a lot of effort. If you’re doing it right, you’ll already feel like you have the workload of a full-time job. This is largely because each application and interview requires individual attention and preparation. Instead of sending out a standardized resume and cover letter, you should tailor your resume to the job in question, and write a unique cover letter for that company.  

You’ll also need to research the organization, its values, and its goals, alongside any information you can find online about its hiring process. 

Remember: Job descriptions are very idealistic. Each company wants to attract the best person they can for the job, which can lead to a list of essential skills and experience that includes many arguably non-essential things. Aside from your time, you have nothing to lose by applying for jobs that seem a little out of your league. When you start applying for jobs, it’s best not to let the details of each post give you doubts, and apply to all the entry-level data modeling positions you run into.
