For most of the data, I&#8217;m storing it using a table with multiple columns for each attribute. However, I&#8217;m now starting to build some of the tables for the content storage. The content in this case, is multiple sections that each contain different data sets; some of the data is common and shared (and foreign key&#8217;d) and other data is very unique. In the current iteration of the application we have a table structure like this:id | project_name | project_owner | site | customer_name | last_updated &#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;-<\/li>\n<li><img decoding=\"async\" src=\"http:\/\/i.stack.imgur.com\/6pskS.jpg?s=32&amp;g=1\" \/><br \/>\ndognose<br \/>\nmysql entity-attribute-value<br \/>\nWe are going to use the EAV Pattern for a szenario, where we will have various different entities with very different attributes.The &#8220;basic&#8221; EAV-Pattern is made out of 3 tables. As different attributes would have different DataTypes (date, long, boolean,&#8230;.) im currently thinking about how to resolve this.First way would be to store everything as a string. This requires &#8220;parsing&#8221; and having a number like &#8216;1&#8217; would not show directly, if this is a double, boolean or anything. Attribute Values Table would look like id|attribute_id|entity_<\/li>\n<li><img decoding=\"async\" src=\"http:\/\/www.gravatar.com\/avatar\/9c9c9387b497937275018d38d02d6e45?s=32&amp;d=identicon&amp;r=PG\" \/><br \/>\njdog<br \/>\nsymfony1 doctrine entity-attribute-value<br \/>\nI have the following schema.yml:JosJeventsVevdetail:connection: doctrinetableName: jos_jevents_vevdetailcolumns:evdet_id:type: integer(4)fixed: falseunsigned: falseprimary: trueautoincrement: truerawdata:type: string()fixed: falseunsigned: falseprimary: falsenotnull: trueautoincrement: falserelations:CustomField: { class: JosJeventsVevdetail, local: evdet_id, foreign: evdet_id, type: one, foreignType: man<\/li>\n<\/ul>\n<p id=\"rop\"><small>Originally posted 2013-11-09 19:02:58. <\/small><\/p>","protected":false},"excerpt":{"rendered":"<p>demonkoryu php magento entity-attribute-value I&#8217;ve noticed that Magento keeps the URL to the logo it uses for each store you setup in the core_config_data table.If I run this SQL:SELECT * F Bill Karwin php database postgresql entity-attribute-value I&#8217;m in the process of rebuilding an application (lone developer here) using PHP and PostgreSQL.
