# Operations This section covers practical operations you can perform with the AQL interface. These guides walk through schema management, table access, document CRUD, index usage, filtering, and foreign key lookups. ## Schema and Instance Management AQL organizes data through schemas and instances: - [2. Schema Management](./2.database_management.md) - Define schemas, create and destroy instances ## Table Access Tables live inside schema instances: - [3. Table Operations](./3.table_operations.md) - Access tables and work with their contents ## Document Operations Documents are the fundamental unit of data in AQL: - [4. CRUD Operations](./4.crud.md) - Insert, read, update, replace, and delete documents ## Index Operations Indexes accelerate queries by enabling efficient lookups: - [5. Index Management](./5.indexes.md) - Define secondary indexes in schema definitions ## Query Operations Transform and filter data with the query builder: - [6. Filtering and Querying](./6.filtering.md) - Filter, compare, and transform documents - [7. Lookup](./7.lookup.md) - Foreign key joins and data population
