# Background Jobs Module
The Background Jobs module implements the `IBackgroundJobStore` interface and makes possible to use the default background job manager of the ABP Framework. If you don't want to use this module, then you should implement the `IBackgroundJobStore` interface yourself.
> This document covers only the background jobs module which persists background jobs to a database. See [the background jobs](../Background-Jobs.md) document for more about the background jobs system.
## How to Install
This module comes as pre-installed (as NuGet/NPM packages). You can continue to use it as package and get updates easily, or you can include its source code into your solution (see `get-source` [CLI](../CLI.md) command) to develop your custom module.
### The Source Code
The source code of this module can be accessed [here](https://github.com/abpframework/abp/tree/dev/modules/background-jobs). The source code is licensed with [MIT](https://choosealicense.com/licenses/mit/), so you can freely use and customize it.
## Internals
### Domain Layer
#### Aggregates
- `BackgroundJobRecord` (aggregate root): Represents a background job record.
#### Repositories
Following custom repositories are defined for this module:
- `IBackgroundJobRepository`
### Database providers
#### Common
##### Table / collection prefix & schema
All tables/collections use the `Abp` prefix by default. Set static properties on the `BackgroundJobsDbProperties` class if you need to change the table prefix or set a schema name (if supported by your database provider).
##### Connection string
This module uses `AbpBackgroundJobs` for the connection string name. If you don't define a connection string with this name, it fallbacks to the `Default` connection string. See the [connection strings](https://docs.abp.io/en/abp/latest/Connection-Strings) documentation for details.
