Detailed explanation-1: -A flat file consists of a single table of data. It allows the user to specify data attributes, such as columns and data types table by table, and stores those attributes separate from applications. This type of file is commonly used to import data in data warehousing projects.
Detailed explanation-2: -A flat-file database is a database stored in a file called a flat file. Records follow a uniform format, and there are no structures for indexing or recognizing relationships between records. The file is simple. A flat file can be a plain text file (e.g. csv, txt or tsv), or a binary file.
Detailed explanation-3: -"In the case of a single-table relational database, there are no relationships between multiple tables, and new columns can be easily added to the single table."
Detailed explanation-4: -The database is flat because every line only holds one data input, depending on the categorization of the columns. Flat file databases store plain text records and binary files that are needed for a specific purpose in a single directory for easy access and transfer.
Detailed explanation-5: -A flat file database is basically a giant collection of data in which the tables and records have no relation between any other tables. In fact, one could have a single table (e.g., My Small Business Data) with everything stored in it, from customers to sales to orders to invoices.
