Nowadays, flow chart is an important productivity tool, serving employees in various industries and functions. In the year 1949, flowchart began to be used for planning computer programs and quickly became one of the most popular tools in designing computer algorithms and programs. Participants from this conference such as Art Spinanger and Ben Grahamthen began to use flowchart in their respective fields, which helped propagate the usage of flowchart. Mogensen, an industrial engineer trained some participants in his Work Simplification Conferences in New York.

In 1921, the couple presented the graphic-based method in a presentation titled: “Process Charts: First Steps in Finding the One Best Way to do Work”, to members of the American Society of Mechanical Engineers (ASME).Īfter that, in 1930s, Allan H.

Branko Ajzele opened a discussion of how to Escape from EAV the Magento way.It is not clear who was the true inventor of flowcharts, but the first standardized documentation on flow chart was first introduced by Frank and Lillian Gilbreth. 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. Try to spend first few hours getting familiar with some background. I advise you not to rush too much figuring out what is what by glancing through database. If you worked with osCommerce, Zen Cart, CRE Loaded or any similar eCommerce platform before, you might find Magento database structure quite confusing when you see it for the first time.
