Topic: Strengths of Relational Databases and NoSQL Solutions
So many data platforms, so little time… which one should you choose?
Data is everywhere in our lives and storage platforms continually evolve. Presented in March, TJ’s lecture provided an overview and comparison of relational databases and NoSQL solutions. Each has strengths, and choosing the right platform requires consideration of many variables. The talk shared strategies to use in determining the best platform. It provided a technical review of some common relational database options and included a discussion on transitioning to a NoSQL solution. TJ’s lecture covered key decision points in determining which platform is best depending on specific needs.
Through his presentation, TJ reviewed RDBMS options: Oracle, MySQL/MariaDB, and PostgreSQL and mentioned some of the NoSQL options, including MongoDB and ElasticSearch. He talked about RDBMS structure, schema, and transaction qualities. Next, he described how NoSQL allows for thinking about data differently and shared some of the benefits of the NoSQL database. Using MySQL and MongoDB, TJ demonstrated differences in uses of database platforms.
Students enjoyed hands-on examples and a question-and-answer period after TJ’s talk. TJ provided resume and job interviewing advice. The event was a success and an honor, and TJ is working with the iSchool to schedule another guest lecture — topic to be determined.

It wasn’t always about software development. “I wanted to be a National Geographic photographer,” Diane admits of her childhood dreams. “We had National Geographicsubscriptions, so I’d flip through the magazines. I asked my parents for cameras. I knew that’s what I wanted to do.” Before college, aptitude tests led Diane to Computer Science. She had a knack for math and saw the success of her cousins who were working in CS. Diane decided a technical path would be worth pursuing. During her college years, she worked fulltime as a junior programmer to pay her tuition and fees.
APRIL DEPETRIS, SENIOR DATABASE ENGINEER,PROFESSIONAL PROBLEM SOLVER“Because I had good grades, they put me in programming class, and I did well.”With a can-do attitude, April takes on the critical challenge of administering two databases. She manages these behemoths for growth, query efficiency, changing requirements, backups, and more. Creation, migration, and building make up just part of her technical toolbox. April gains immense satisfaction from solving problems, and she takes on the challenges of database engineering with flexibility and determination every day.
“I like to build stuff,” she explains. As a young girl, April enjoyed art and making things with her hands. She worked on circuit boards, Erector Sets, and Lincoln Logs. When she was scheduled to take an elective high school sewing class, April drew a line, telling her mom she didn’t like sewing at all. Instead, the school cautiously placed her in a basic programming class. She was considered too young to master the material, but April thrived in the world of programming and resolved to pursue more technical courses. At UMBC, Computer Science was a natural fit. “I got my first IBM when I got to college,” April recalls. From there, she didn’t turn back, accepting her first development job when Visa’s Owings Mills office launched its development department.
