Relational Module

Bring all your product data together – no matter where it lives

Many catalogs are built from data spread across multiple files, tables, or systems. Products may be in one source, variants in another, pricing in a third, and accessories somewhere else entirely. The Relational Module is designed to solve exactly that.

It lets you combine multiple datasources into a single, structured hierarchy inside EasyCatalog, giving you a clean, unified view of your entire dataset — ready for sorting, grouping, filtering, and full automation.

If your catalogue needs parent/child relationships, multi-level groupings, or data that spans several tables, this is the module you need.

What the Relational Module does

Combine multiple datasources (CSV, XML, ODBC, PIM and more) into one cohesive hierarchy
Create parent/child relationships — products → variants, products → accessories, categories → products, etc.
Build multi-level structures for complex catalogs
Search and navigate across all linked data as if it came from a single table

Under the hood, the module uses a fast, local SQLite engine to manage your data — giving you database-level speed and flexibility without requiring any server setup.

Typical use cases

The Relational Module is ideal when you need to:

Build catalogs where product details, variants, pricing, translations, and images are stored in separate files or systems
Link accessories, spare parts, or related items beneath their main products
Create multi-language publications where each language lives in a separate datasource
Combine data from multiple suppliers or brands into one structured catalogue
Display grouped or nested data (e.g., Brand → Product Line → Product → Variants)
Merge live database content with static reference data or lookup tables
Produce large, multi-level price lists or technical catalogs with complex data relationships

If your data has one-to-many or many-to-many relationships, this module gives you the tools to organise and publish it cleanly.

Supported Data Sources

If your publication consists of data retrieved from different types of data sources, the Relational Module can combine these into a single EasyCatalog panel. The Relational Module will link data from any of the data sources supported by EasyCatalog and the optional modules, such as CSV, XML, ODBC and Product Information Systems.

The module places no restrictions on how many datasources you can link together.

How it works

Import or connect your datasources
Use the Relational Setup panel to define how they relate (product → variants, product → prices, etc.)

Refresh your data to build the unified hierarchy
Use the combined view just like any other EasyCatalog panel

Your data is indexed, structured, and ready for fast, powerful publishing.

For example, if your database contains a list of products that have two sets of attributes – both retrieved from different database tables – the Relational Module can query for these separately and display the results in the data panel.

Do I need the Relational Module?

You’ll benefit from this module if:

Your data isn’t all in one table, or the data cannot be represented in a single data set
You have different data sources for different parts of a product

If your data is already in a single flat table, the core EasyCatalog module may be all you need — but as soon as your structure gets more complex, the Relational Module pays for itself.
