9The bundle management framework is provided by OpenHarmony for you to manage application bundles \(installation packages\). The following figure shows the architecture of the bundle management framework.

14- **BundleKit** includes external APIs provided by the Bundle Manager Service, including the APIs for application installation and uninstallation, bundle information query, and bundle state change listeners.
15- The **bundle scanning sub-module** parses pre-installed or installed bundles on the local device and extracts information from them for the bundle management sub-module to manage and make the information persistent for storage.
16
17- The **bundle installation sub-module** installs, uninstalls, and updates a bundle.
18- The **bundle installation service** is an independent process used to create or delete installation directories and has high permissions.
19
20- The **bundle management sub-module** manages information related to application bundles and stores persistent bundle information.
21
22- The **bundle security management sub-module** verifies signatures, and grants and manages permissions.

41- The Bundle Manager Service is running in the foundation process.
42- The Bundle Manager Service is registered with **sa\_manager**. **sa\_manager** runs in the foundation process and sets up a thread runtime environment for the service. For details about how to create and use the Bundle Manager Service, see [SA Framework](en-us_topic_0000001051589563.md).
43- The Bundle Manager Service starts upon OS startup.
44- You can use the bm tool to install the specified HAP. \(Taking **hispark\_taurus** as an example, you can obtain the bm tool from the **out/hispark\_taurus/ipcamera\_hispark\_taurus/dev\_tools/bin directory** after the version building.\)
