The database structure was one of the biggest bottlenecks with Magento 1. It was difficult to customize Magento 1 to run on numerous databases or even split some particular functions like checkout, catalog, and customer to execute on an individual master database through background data synchronization.

However, Magento 2 comes with an alternative to employ three individual master databases for different functional area which further permits users to split the load for checkout, order management, catalog browsing, etc. Even though it is accessible only with the EE version. This promising feature of Magento 2 is a right fit for all those merchants who has been struggling to sustain their peak traffic throughout the holiday season.

Magento 2 still employs the EAV (Entity Attribute Value) database structure for such entity as product, category, customer address, order, etc… But, there are some major differences in the database structure of Magento 1 and Magento 2.

So, without no further ado, let’s dive into such differences!

  • In Magento 1.9, the default tables at the time of installation is equal to 333, and System attribute comes with 131 attributes.

However, Magento 2 has 296 default tables at the time of installation with 129 system attributes.

  • Magento 1.x has the core_resource as the module register table and it is not available with the Magento 2. The name of such table that registers the module is setup_module, and version with schema_version. data_version is the same.

Apart from aforementioned differences, the names are also changed for some other tables. Let’s have a look at these names:

core_store to store

core_store_group to store_group

core_website to store_website

admin_role to autorization_role

admin_rule to authorization_rule

The structure of core_store, and core_store_group tables has also been changed.

Apart from these changes, the aforeshared tables do not have any structural changes.
