 # dlt
 
 [dlt](https://dlthub.com/) stands for "data load tool". It's an open-source Python library providing a ton of data `Sources` (Slack, Stripe, Google Analytics, Zendesk, etc.) and `Destinations` (S3, Snowflake, BigQuery, Postgres, etc.). `Pipelines` make it easy to connect `Sources` and `Destinations` and provide advanced engineering features such as table normalization, incremental loading, and automatic schema evolution.

 # FastAPI
 
 [FastAPI](https://fastapi.tiangolo.com/) is an open-source Python web framework to create APIs. It is a modern alternative to [Flask](https://flask.palletsprojects.com/en/3.0.x/) and a more lightweight option than [Django](https://www.djangoproject.com/). In FastAPI, endpoints are defined using Python functions. The parameters indicate the request specifications and the return value specifies the response. Decorators are used to specify the [HTTP methods](https://learn.microsoft.com/en-us/azure/architecture/best-practices/api-design) (GET, POST, etc.) and to route the request.

 # Ibis
 
 [Ibis](https://ibis-project.org/) is the portable Python dataframe library. It allows you to define data transformations once and execute them in multiple backends (BigQuery, DuckDB, PySpark, SQLite, Snowflake, Postgres, Polars; [see the full list](https://ibis-project.org/support_matrix)). If you never used Ibis before, it should feel similar to SQL with a touch of dataframes (e.g., pandas). You'll be primarily writing expressions (similar to an SQL query), which compute values only after calling for execution via `.to_pandas()` for example.
