• Data duplication
• Data inconsistency or update/deletion/insertion anomalies
• Data integrity errors (due to data inconsistency)
• Inconsistent search results in multi-value fields
Flat file databases are also called as relational databases describe any different means to encode a database model. This requires data to be kept in one large table. Big up Philip Proctor
A flat-file database is a simple database system that stores data in a single table or file, typically in a plain text format, such as CSV or TSV. Each record is usually represented as a single line, with fields separated by delimiters like commas or tabs. Unlike relational databases, flat-file databases do not support complex relationships between data sets or advanced querying capabilities, making them suitable for small-scale applications or simpler data storage needs. Their ease of use and straightforward structure make them accessible for basic data management tasks.
A spreadsheet is one example. All the data is in a single table.

Flat file databases are not considered as Databases, rather they are files that are used as Databases.Some constraints with Flat File Databases:1. Slow access to information.2. Less reliability (prone to corruption).3. Doesn't offer scalability as Information size grows.4. Adding new categories id difficult
File system data management (or flat-file databases) served as the only method of file storage and retrieval before the advent of database management systems (such as relational databases). While retaining some use, flat-file databases suffer from poor accessibility, data redundancy, lack of standard file access and the inability to organize data.

A flat file system usually stores the same type of information over and over again, whereas a relational database does not. A flat file system might store zip-codes and their explanation (location of the zip code) over and over again, each time per record. A relational database stored the explanation for any given zip-code only once, and looks that information up when it needs it. --
A flat file is in a list format (containing only one table) while databases uses different tables to store data. It is easier and faster to locate data in a database than in a flat file.
Flat file databases have a simple structure, making them easy to create and understand. They are typically faster to access than relational databases since there are no complex relationships to navigate. Additionally, flat file databases are often more portable and can be easily transferred between different systems or applications. However, they may not be suitable for complex data relationships or large datasets due to their lack of normalization and potential for data redundancy.
A database in which ALL the data is stored in a single table is known as a flat-file database. This type of database lacks the relational structure found in more traditional databases that use multiple tables to store and organize data. Flat-file databases are simple but may limit the ability to efficiently query and manage data.
A flat file is a simple file containing data without any structured format, while a Database Management System (DBMS) is a software system that manages databases by organizing, storing, and retrieving data. A DBMS allows for more organized and efficient data management, supports relationships between data, and provides features like security and data integrity that are not available with flat files.
When you store your data in a ordinary plain text file, for example as comma-separated values with one entry per line.Traditional (non-flat-file) databases do not do this, they bypass the file system altogether and store the data in a big binary blob in a custom format that cannot be read by anyone except the database program itself.See related Wikipedia link.
Relational database has many advantages over the flat file database: 1. Avoids data duplication. 2. Avoids inconsistent records. 3. Easier to change data. 4. Easier to change data format. 5. Data can be added and removed easily. 6. Easier to maintain security.
A .dbf file is used with databases.
