Otherwise, flat file database is implemented in Microsoft Works and Apple Works. With the in-memory concept, WebDNA searches and database updates are almost realtime while the data is stored as text files within the website itself. WebDNA is a scripting language designed for the World Wide Web, with a hybrid flat file in-memory database system making it easy to build resilient database-driven websites.

Contemporary implementationsįairCom's c-tree is an example of a modern enterprise-level solution, and spreadsheet software and text editors can be used for this purpose. Some of these, like dBase II, offered limited relational capabilities, allowing some data to be shared between files. Examples of flat-file database products were early versions of FileMaker and the shareware PC-File.
These programs were designed to make it easy for individuals to design and use their own databases, and were almost on par with word processors and spreadsheets in popularity. In the 1980s, configurable flat-file database computer applications were popular on DOS and the Macintosh. IBM's fixed-length field, 80-column punch cards became the ubiquitous means of inputting electronic data until the 1970s. Hollerith's enterprise grew into computer giant IBM, which dominated the data processing market for most of the 20th century.

He sold his concept to the US Census Bureau thus, the Census of 1890 was the first ever computerized database-consisting, in essence, of thousands of boxes full of punched cards. Herman Hollerith conceived the idea that census data could be represented by holes punched in paper cards and tabulated by machine. The first uses of computing machines were implementations of simple databases. A spreadsheet or text editor program may be used to implement a flat file database, which may then be printed or used online for improved search capabilities. This can also be done with any typewriter or word processor. Another example of a flat file is a name-and-address list with the fields Name, Address, and Phone Number.Ī list of names, addresses, and phone numbers written by hand on a sheet of paper is a flat file database. Typical examples of flat files are /etc/passwd and /etc/group on Unix-like operating systems. There are usually no structural relationships between the records.
Extra formatting may be needed to avoid delimiter collision. In the latter case, short values may be padded with space characters. Within such a record, the single fields can be separated by delimiters such as comma or tab characters, or may have a fixed length. A flat file can be a plain text file, usually containing one record per line, or it can be a binary file.
