ZEN DIAGRAM AUTHOR HOW TO
Branko Ajzele opened a discussion of how to Escape from EAV the Magento way. Mladen Lotar expanded this intro and provided more details at his Magento’s database layout and it’s EAV structure article at 2010, while in 2009. This topic was discussed on two more following articles from my colleagues. The author of Database Diagram is Gordon Goodwin, IT Consultant. Additional informal/undiagrammed table relationships may also exist, so when modifying the schema or directly manipulating data it is important to identify and evaluate possible changes to these tables as well (and the tables they relate to, and the tables they relate to…).
Table relationships depicted in the diagrams represent only those relationships explicitly defined as Foreign Keys in the Magento database. Diagrams in this post contain a section labeled “EAV” which displays Magento’s core EAV tables and thier relationships to non-EAV tables.ĭownload Magento 1.1.6 MySQL database diagram (PDF)ĭownload Magento 1.3.2.4 MySQL database diagram (PDF)ĭatabase diagrams and documents found in this post are intended to mirror the database schema as defined by Varien. Core EAV tables are prefixed with “EAV_”. Varien has simplified the identification of EAV related tables with consistent naming conventions. Therefore, an understanding of EAV principles and how they have been modeled into Magento it is HIGHLY recommended before making changes to the Magento data or the Magento schema ( Wikipedia: Entity-attribute-value_model). Is there something in Magento that is simple from developers point of view?ĭata manipulation in Magento is often more knowledge demanding than that typical use of traditional relational tables. As is often the case, the cost of flexibility is complexity. For purposes of flexibility, the Magento database heavily utilizes an Entity-Attribute-Value (EAV) data model.

Red text refers to geographical areas, blue text refers to political entities. It might not look that great, but it's the best way to illustrate it. Additionally, the Ireland (as in the island) text is now in the middle. This version, unlike the PNG version on Wikipedia, features some small changes and improvements, including referring to the Republic of Ireland as such instead of just "Ireland".
