Collections
Overview
Collection
A Collection refers to a grouping or container for related data records. The term is often associated with NoSQL, non-relational databases, particularly document-oriented databases like MongoDB.
Document
A Document refers to an individual data entry within a collection. It is essentially a single instance of data that conforms to the structure defined by the collection. It typically consists of key-value pairs. Each key represents a field, and the corresponding value is the data associated with that field.
Field
A Field refers to specific piece of data or attribute within a document. EZbase supports the following field types:
| Field | Example values |
|---|---|
| string | "", "Hello World!" |
| number | 0, 4, -5, 1.9 |
| bool | true, false |
| array | [], [1, 4, 5], ["apples", "oranges", "bananas"] |
| object | const person = { firstName: 'John', lastName: 'Doe', age: 30, email: 'john.doe@example.com', isStudent: false }; |
Creating Collections & Records
There are two ways to make a collection and its subsequent records:
- Admin UI
- API (through client-side SDKs)
A typical way utilizing these two would be to create the collection using the Admin UI and then manage the records within the collection with the API using the client-side SDKs.
An example of a collection in the Admin UI is as follows:
