If you’ve ever wondered how apps store your login info, websites remember your shopping cart, or businesses manage customer data, chances are a database is working quietly behind the scenes. One of the most popular types of databases is an SQL database. But what exactly is it?

At the heart of this post is Kairos IMS, an innovative Impact Management System designed to empower human-serving nonprofits and social impact organizations. Co-developed by the Urban League of Broward County and our trusted technology partner, Impactful, Kairos IMS reduces administrative burdens, enhances holistic care, and enables organizations to leverage data for increased agility and seamless service delivery.

What Does SQL Stand For?

SQL (pronounced "ess-cue-ell" or sometimes "sequel") stands for Structured Query Language. It's a standardized programming language used to manage and manipulate relational databases—a type of database that stores data in tables, similar to a spreadsheet.

What Is an SQL Database?

An SQL database is any database that uses SQL to query and manage the data it holds. It organizes information into tables, which are made up of rows (records) and columns (fields). These tables can be linked to each other using relationships, making it easy to combine and retrieve related data efficiently.

For example, an online store might have:

  • A Customers table (name, email, phone number),
  • An Orders table (order ID, customer ID, product ID),
  • A Products table (product name, price, stock count).

With SQL, the business can easily pull reports like “show all orders placed by John Doe” or “list products low in stock.”

How Nonprofits Can Use SQL Databases

Imagine you're running a youth mentorship program. You could use an SQL database to manage:

  • Participants (name, age, school, enrollment date)
  • Volunteers (contact info, availability, background check status)
  • Sessions (which mentor met with which student, when, and where)

With a few SQL queries, you could:

  • Generate a monthly report on how many mentorship hours were logged
  • See which students have missed more than two sessions
  • Pull contact information for all volunteers available on Tuesdays

What Can You Do with SQL?

SQL allows you to:

  • Create and modify databases and tables
  • Insert, update, and delete records
  • Query data using commands like SELECT, WHERE, and JOIN
  • Set up permissions for who can access or change the data

Common SQL Database Systems

Several software systems (called Database Management Systems, or DBMS) use SQL. Some popular ones include:

  • MySQL – free and open-source, widely used for websites
  • Microsoft SQL Server – enterprise-level database used by many businesses
  • PostgreSQL – powerful open-source DBMS with advanced features
  • SQLite – lightweight, often used in mobile apps
  • Oracle Database – robust and scalable, commonly used in large corporations

Why Are SQL Databases Important?

SQL databases are trusted for:

  • Data integrity: ensuring accuracy and consistency
  • Scalability: handling large amounts of data as your needs grow
  • Security: controlling who can view or edit information
  • Reliability: mature systems that are well-tested in real-world use

Conclusion

SQL databases are the backbone of modern data management. Whether you’re building a website, managing customer records, or running a business, understanding SQL gives you the tools to organize and retrieve your data efficiently. Even a basic knowledge of SQL can open doors in tech, analytics, and beyond.

 

An SQL database can be a game-changer for nonprofits looking to stay organized, demonstrate impact, and scale their operations. Whether you're a grassroots organization just starting out or an established nonprofit ready to modernize your systems, understanding SQL is a smart step toward using data for good.
