# Create an Inventory System in DOTS

Build a DOTS-based inventory system with ECS components, efficient queries, UI integration, and performance-focused patterns.

In this webinar, we will build a complete inventory system using Unity's Data-Oriented Technology Stack (DOTS), inspired by the grid-based mechanics found in V Rising. We will cover ECS component architecture, efficient data queries, UI integration patterns, and performance optimization techniques specific to inventory management systems.

**Session objectives:**

- Design ECS components for items, inventory slots, and container systems using data-oriented principles.
- Implement core inventory operations including item addition, removal, stacking, and grid-based placement logic.
- Integrate DOTS systems with Unity's UI frameworks for responsive inventory interfaces.
- Apply performance optimization strategies for large-scale inventory operations and real-time updates.
- Develop extensible patterns that support advanced features like auto-sorting, item categories, and multiplayer synchronization.
