## What it is
ElectroDB is a TypeScript library for AWS DynamoDB that simplifies modeling multiple entities and complex hierarchical relationships in a single table (Single Table Design). It provides schema enforcement, entity isolation, and a readable query builder for access patterns.

## Use cases
- model multiple entities in a single DynamoDB table
- implement single table design on DynamoDB
- define validated schemas for DynamoDB entities
- build hierarchical access patterns with composite keys
- write readable sort key condition queries
- avoid key conflicts between entities sharing one table

## When to choose
- you use DynamoDB and want structured entity modeling with validation
- you are adopting single table design with multiple entity types
- you want readable, composable queries instead of raw DynamoDB expressions
- your data has complex hierarchical relationships and many access patterns

## When to avoid
- you use SQL or non-DynamoDB databases
- you prefer raw DynamoDB document client control with no abstraction
- your project is not on the Node.js/TypeScript ecosystem
- you need a full ORM with migrations and relational joins

## Facets
- artifact type: library
