Unlike traditional file storage which uses a hierarchical tree structure, Huawei Object Storage utilizes a flat structure where each " object " is a self-contained unit of data. According to the documentation, an object consists of four fundamental components:
Data (Option D): The actual content of the file (e.g., a photo, video, or document).
System Metadata (Option C): These are fixed attributes managed by the storage system, such as file size, creation date, last modified time, and HTTP content type.
Customized Metadata (Option B): A unique advantage of object storage is the ability to attach user-defined tags or labels to an object (e.g., " Patient_ID: 12345 " or " Department: Radiology " ). This allows for advanced data indexing and searching without opening the file itself.
Object Identifier (OID) (Option A): This is the unique key or " Address " used to retrieve the object. In a flat namespace, the OID ensures that every piece of data can be located instantly without traversing a complex directory path.
