SQL for Ecology

Databases are useful for both storing and using data effectively. Using a relational database serves several purposes.

This lesson will teach you what relational databases are, how you can load data into them and how you can query databases to extract just the information that you need.

Getting Started

Data Carpentry’s teaching is hands-on, so participants are encouraged to use their own computers to insure the proper setup of tools for an efficient workflow.
These lessons assume no prior knowledge of the skills or tools.

To get started, follow the directions in the “Setup” tab to download data to your computer and follow any installation instructions.

Prerequisites

This lesson requires a working copy of SQLite Manager for SQL.
To most effectively use these materials, please make sure to install everything before working through this lesson.
