What is the main purpose of Teradata Studio's SQL Query Developer?

The main purpose of Teradata Studio's SQL Query Developer is to build and manage SQL queries visually. This tool is designed specifically for database tasks, allowing users to create, edit, and execute SQL queries through a user-friendly graphical interface. It simplifies the process of writing complex SQL statements by providing visual aids, which is particularly beneficial for users who may not be entirely comfortable with writing SQL code directly.

The emphasis on visual representation means that users can see the overall structure of their queries and make adjustments easily, which contributes to more efficient query development and troubleshooting. Being able to construct SQL queries this way enables users to focus more on the logic of their queries rather than the syntax, thus streamlining the development process.

The other choices involve functionalities that are not the primary focus of Teradata Studio. For instance, running machine learning models and creating data visualization dashboards require separate tools or environments tailored specifically for those purposes. Similarly, performing statistical analyses typically involves different specialized software that goes beyond the capabilities of SQL Query Developer.
