# Collection protocol
|
|
|
|
Collection is the backbone of NocoBase, a protocol for describing data structures (collections and fields), very close to the concept of a relational database, but not limited to relational databases, but can also be a data source for NoSQL databases, HTTP APIs, etc.

|
|
|
|
At this stage, the Collection protocol is based on the relational database interface (db.collections), and data sources such as NoSQL databases and HTTP APIs will be implemented gradually in the future.
|
|
|
|
Collection protocol mainly includes two parts: CollectionOptions and FieldOptions. Because Field is extensible, the parameters of FieldOptions are very flexible.
|
|
|
|
## CollectionOptions
|
|
|
|
```ts
|
|
interface CollectionOptions {
|
|
name: string;
|
|
title?: string;
|
|
// Tree structure table, TreeRepository
|
|
tree?: 'adjacency-list' | 'closure-table' | 'materialized-path' | 'nested-set';
|
|
// parent-child inheritance
|
|
inherits?: string | string[];
|
|
fields?: FieldOptions[];
|
|
timestamps?: boolean;
|
|
paranoid?: boolean;
|
|
sortable?: CollectionSortable;
|
|
model?: string;
|
|
repository?: string;
|
|
[key: string]: any;
|
|
}
|
|
|
|
type CollectionSortable = string | boolean | { name?: string; scopeKey?: string };
|
|
```
|
|
|
|
## FieldOptions
|
|
|
|
Generic field parameters
|
|
|
|
```ts
|
|
interface FieldOptions {
|
|
name: string;
|
|
type: string;
|
|
hidden?: boolean;
|
|
index?: boolean;
|
|
interface?: string;
|
|
uiSchema?: ISchema;
|
|
```
