Map Documentation: Poultry Farm Discovery (BDN)

1. 1. Abstract

This dataset provides a comprehensive list of **valid**, **open**, and **closed** poultry farms registered in the National Data Bank (BDN). It specifically filters for farms categorized as 'Breeding' (AL) or 'Mixed' (MS) across Italy. The data is processed through a join between the poultry breeding facts and the 'Places' (Luoghi) dimension (filtered for valid/open locations). It also incorporates owner/holder details via an outer join with the 'Registry' (Anagrafe) dimension and housing data via the 'Poultry Housing' (Accasamenti) dimension.

-== Lineage & Technical Logic ==
-The dataset is extracted based on the following logic:
-# **Validity Check:** Execution date must fall between `AVIDATA_VALSTART` and `AVIDATA_VALEND`.
-# **Activity Filter:** `tipologia_attivita` MUST be 'AL' (Breeding) or 'MS' (Mixed).
-# **Relational Joins:** #* **Inner Join:** `IZIADMIN.LUOGHI` (Filtered for valid/open sites).
