# 2022-04-07: CE - Catalog and Category
### Overview
To meet the complexity and scale of B2B Commerce needs, we have redesigned our implementation of how products are stored, categorized and managed in the Emporix platform.
### New features
#### Catalog Service
We have introduced a new feature called Catalog, which acts as a container for Categories and Products. A Catalog acts as a “root node” of a collection of Categories.
| **Features** | Benefits |
| -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Multiple Catalogs per Tenant** | A tenant can create and manage multiple catalogs for different purposes. For example:
- Supplier and Seller Catalogs
- One Catalog per Product Line or Division
- Seasonal Catalogs
|
| **Multiple Catalogs per Site** | More than one Catalog can be published on a site at the same time. For example: Product Catalog and Promotional Seasonal Catalog. |
| **Catalog Visibility** | Catalogs have a flag to set whether they are visible in the storefront or not, and additionally have a visibility date range that can automatically control the dates they should be visible from and to. For example: Promotional or Seasonal Catalog can be automatically made visible and expired from the storefront based on pre-set date ranges. |
| **Multi-language Support** | Category attributes (such as name and description) support language Localization. |
#### Category Service
We have also completely redesigned our Category Service implementation to support a much more flexible structure. Categories can be nested and once created can be easily moved around to restructure the collection the best way for your business.
| **Features** | Benefits |
| ------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Category supports multiple views** | Category structures can be viewed either as a flat list or as a hierarchical structure to better see the parent/child relationships for easier browsing and understanding. |
| **Category Visibility** | Categories have a flag to set whether they are visible in the storefront or not, and additionally have a visibility date range that can automatically control the dates they should be visible from and to. For example: Specific Categories can be automatically made visible and expired from the storefront based on pre-set date ranges. |
| **Multi-language Support** | Catalog attributes (such as name and description) support language Localization. |
| **Category Assignment** | Categories can be assigned to one, and only one Catalog. |
| **Product Assignment** | Products can be assigned to one or more Categories. |
Both Catalogs and Categories work with our existing Product Service to provide greater flexibility and scalability in how our customers manage the goods that they sell through their digital commerce channels.
