In early file-based systems, data was typically stored in individual files that were organized in a hierarchical or flat structure. Each file contained a specific type of data, such as customer information, sales records, or inventory data.
To access and manipulate the data, users would need to know the exact location and structure of the files. This often required a detailed understanding of the file system and the specific file naming conventions used.
Data was typically stored on physical storage devices such as hard drives, floppy disks, or magnetic tapes. Backing up and restoring data was a manual process that often involved copying files to separate storage media.
Data integrity and security were major concerns in early file-based systems, as there was no centralized control over access to files. Users could potentially overwrite or delete important data if they were not careful.
Overall, the handling of data in early file-based systems was complex and required a high level of technical expertise to manage effectively.

Early File-Based System Data Handling Approach
In early file-based systems, data handling was primarily focused on:
1. Direct Access to Physical Storage:
- Stored data directly on physical storage devices (e.g., magnetic tapes, hard disks).
- Users accessed data by explicitly specifying the physical location (e.g., track, sector) on the storage device.
- This approach provided fast access to small amounts of data but was inefficient for large datasets and required specialized knowledge.
2. Sequential Processing:
- Data was stored in a sequential order on storage devices.
- To access a specific record, the system had to read through all preceding records.
- This approach was suitable for batch processing applications where data could be processed in a predictable order.
3. File Management System (FMS):
- An intermediate layer between the user and the physical storage device.
- Managed the creation, deletion, and modification of files.
- Provided basic data manipulation functions (e.g., read, write, append).
- Standardized access methods to simplify data retrieval and updates.
4. File Structure:
- Basic file structures included:
- Flat File: A single, unstructured collection of data records.
- Sequential File: Records ordered in a chronological or logical sequence.
- Hierarchical File: Records organized in a tree-like structure.
- The choice of file structure depended on the specific application requirements.
5. Data Formats:
- Data was typically stored in a raw, unprocessed format.
- The interpretation and formatting of data was left to the application or user.
- This approach allowed for flexibility but required additional processing overhead.
Limitations:
- Limited data access and manipulation capabilities.
- Difficult to manage data with complex relationships.
- Inefficient processing of large datasets.
- Lack of data security and integrity.
