# Corral Framework: Trustworthy and Fully Functional Data Intensive Parallel Astronomical Pipelines

## TL;DR

Corral is a Python framework that simplifies the creation of trustworthy, high-quality astronomical data processing pipelines by integrating a Model-View-Controller design with database management and parallel computing.

## Contribution

It introduces a novel Python framework with a Model-View-Controller pattern, database integration, and quality metrics for building reliable astronomical pipelines.

## Key findings

- Supports custom data models and processing stages.
- Enables multi-processing and distributed computing.
- Provides automatic quality and structural metrics.

## Abstract

Data processing pipelines represent an important slice of the astronomical software library that include chains of processes that transform raw data into valuable information via data reduction and analysis. In this work we present Corral, a Python framework for astronomical pipeline generation. Corral features a Model-View-Controller design pattern on top of an SQL Relational Database capable of handling: custom data models; processing stages; and communication alerts, and also provides automatic quality and structural metrics based on unit testing. The Model-View-Controller provides concept separation between the user logic and the data models, delivering at the same time multi-processing and distributed computing capabilities. Corral represents an improvement over commonly found data processing pipelines in Astronomy since the design pattern eases the programmer from dealing with processing flow and parallelization issues, allowing them to focus on the specific algorithms needed for the successive data transformations and at the same time provides a broad measure of quality over the created pipeline. Corral and working examples of pipelines that use it are available to the community at https://github.com/toros-astro.
