## What are datasets?

Datasets give you direct access to our complete database of jobs, technology usage, and company information. Think of them as your raw data goldmine – perfect when you need maximum flexibility for advanced analytics, machine learning projects, or custom analysis.

We've got two powerful datasets ready for you:

-   **[Jobs Dataset](/en/jobs-dataset)**: Access our complete collection of 205M job postings from 195 countries, dating back to 2021. Each job record includes essential details like job title, description, salary, location, company name, company URL, company industry, company size... Check out the complete [data dictionary](https://app.theirstack.com/dataset) for all available fields.
    
-   **[Technographics Dataset](/en/technographics-api)**: Dive into 49M technology usage signals across [12M companies](/en/docs/data/company/statistics) using 32k different technologies. This isn't just one file – you'll get three comprehensive datasets: the main technographics data (company\_id, technology\_slug, confidence\_score, n\_jobs...), detailed company profiles (including domain, country, revenue, and employee count), and a complete technology catalog with descriptions and categories.
