File Processing System

What is File Processing System?

A File Processing System, in computer science, is a method to read, write, modify, and store data in files. These systems typically fall under traditional data management systems and are prevalent in businesses with simpler, less-interactive data storage requirements.

Functionality and Features

File Processing Systems offer direct access to files for reading, writing, and modifying data. They store data in a structured manner, often in text or binary format. Key features include file organization, sequential access to files, and file-level data manipulation.


The architecture of a File Processing System consists of direct access to data files. It lacks a concept of a database, and hence, data is generally not interrelated. However, metadata is often maintained to track file locations, file size, and file access permissions.

Benefits and Use Cases

File Processing Systems offer simplicity and direct control over data. They're particularly useful in simpler applications like local data storage, transaction logging, or single-user databases. They're also advantageous for storing large volumes of uncorrelated data.

Challenges and Limitations

With File Processing Systems, duplication of data, lack of security, and poor data integrity are common. As data grows, maintaining and managing files can become challenging. Additionally, as these systems lack a schema, analyzing complex data relationships can be difficult.

Integration with Data Lakehouse

In a data lakehouse environment, File Processing Systems can serve as a simple initial data ingestion system. They can be employed to store raw data before it's cleaned, transformed, and loaded into a more sophisticated system like a data lakehouse. However, for real time analytics, machine learning, or more complex queries, data lakehouses provide superior scalability and performance.

Security Aspects

File Processing Systems typically rely on file-system level security. The administrator controls access to data files, and permissions are granted at the file level. However, these systems lack finer-grained data control, sheer compartmentalization, and advanced security protocols like those found in DBMS or data lakehouses.


The performance of File Processing Systems is often ideal for simpler data tasks. However, as data grows and queries become complex, performance often deteriorates. When compared to systems like data lakehouses, their performance in large-scale applications, complex data analysis, and real-time processing is typically inferior.


When compared to Dremio's Data Lakehouse, File Processing Systems lack in flexibility, scalability, performance, and security. Dremio's ability to handle large volumes of data, its agility in data querying, and its built-in security protocols make it a superior choice for businesses needing sophisticated data solutions.


What is a File Processing System? A File Processing System is a type of data handling method that uses files for data storage and management.

How does a File Processing System differ from a DBMS? A DBMS typically uses a database, enabling complex data relations, while a File Processing System lacks complex relationships between data and is often less secure.

Can File Processing Systems be used with data lakehouses? Yes, they can serve as initial data ingestion systems in a data lakehouse setup.

What are the limitations of File Processing Systems? Main limitations include data duplication, poor data integrity, lack of complex data relationships, and issues related to scale and performance.

How does Dremio's technology surpass File Processing Systems? Dremio's data lakehouse handles large data volumes, provides superior querying speed, and offers advanced security, making it more suitable for complex data solutions.
