In database management, a query is a request for information stored in relational databases. Queries are crafted using a SQL-like syntax and executed by the database engine, which will then retrieve the data from your tables and transform it into a human-readable format like a table, graph, or complex result like a trend analysis.
Generally, database queries filter or aggregate your data to help you make decisions quickly and automate repetitive tasks. They can also simplify your underlying data to enable easier access, and they can help you analyze and manage your data more effectively.
A SELECT query can return data from one or more tables, while a DELETE query will remove matching records from your database. If you want to filter results by a specific column, use an ORDER BY query. You can also use a GROUP BY query to combine multiple groups of rows into a single report.
The Brainly team has been working hard to improve Snap to Solve to support even more students and teachers. The Krakow-based technology company democratizes education by providing a free, collaborative online learning platform where students can ask questions and get expert answers 24/7.
During COVID-19, Brainly saw a huge surge in traffic as new and existing users sought out expert help online. To handle the influx, the Brainly team turned to Google Cloud and its scalability and performance capabilities to support users from 35 countries. Vision AI is a key part of the Brainly app that enables students to snap photos of written questions, which the technology then recognizes with optical character recognition (OCR) and converts into text.
