What is Flat File Storage?
Flat File Storage is a type of data storing method that saves information in plain text format or binary form. Each file in this system is standalone, containing all the necessary data, hence lacks the complex structuring and relationships found in databases.
Functionality and Features
Flat File Storage is characterized by its simplicity and accessibility. It includes features such as:
- Simple Structure: Data is stored in a simple, tabular form with rows and columns similar to a spreadsheet.
- Ease of Reading and Writing: Flat files can be easily read and written by numerous programs due their simplicity.
- No Relationships: As each file is independent in flat file storage, there's no need to manage complex relationships between datasets.
Architecture
Flat File Storage operates as a simple data table where each line represents a record (row) and columns represent fields. Each field contains a different type of data, like names, addresses, etc. The rows and columns structure makes the data manipulation quite straightforward.
Benefits and Use Cases
Flat File Storage offers several advantages:
- Readability: Due to their simplicity, flat files are understandable by humans and easy to interpret by software.
- Portability: They are widely supported, making them highly portable across different systems.
- Efficiency: Flat files are straightforward to design and maintain, making them cost-effective for smaller datasets.
Challenges and Limitations
Despite its advantages, Flat File Storage also has limitations:
- Scaling Issues: As the data grows, managing and finding information in flat file systems becomes more complex and time-consuming, which can lead to performance issues.
- No Relationships: The absence of relationships and normalization can cause data redundancy.
Integration with Data Lakehouse
Flat File Storage can serve as an input source for building a data lakehouse. The simplicity of flat files makes them easy to ingest, and their portability ensures compatibility across different data lakehouse platforms.
Security Aspects
Flat File Storage doesn't inherently provide security measures, so data protection is typically provided at the operating system or application level. Authorization and encryption methods can be implemented to secure the data.
Performance
For smaller datasets, Flat File Storage offers high performance due to its straightforward structure and lack of relationships. However, as volume increases, performance may decrease due to complexity in managing large data sets.
FAQs

Glossary
Flat File: A text or binary file in which data is saved in a simple tabular format.
Data Lakehouse: A technology that combines the features of data warehouses and data lakes, promoting efficient data management and analysis.
Data Redundancy: This occurs when the same piece of data is stored in multiple places, often leading to inconsistencies.
Normalization: A method used in databases to minimize data redundancy and complexity.
Dremio and Flat File Storage
While Dremio can ingest data from flat files, it is designed to manage and analyze vast amounts of data better than a flat file system. Dremio leverages a lakehouse architecture, allowing seamless integration and efficient management of data from multiple sources, including flat files, while offering superior performance, security, and data governance.
