What is a file based database? -


i enrolled in course relational databases. asked research advantage of file based approach versus relational databases.

i find easier understand relational databases having difficulty understanding file based systems. file based systems same storing files on windows hierarchical system, meaning text files stored under folders , directories? plain csv files example of file based system?

when refer file-based databases mean databases interact with/update directly (via sql abstraction offered jdbc driver) in essence read/write file directly. example sqlite

no, csv comma separated values file allows data saved in table structured format.

a "flat file" database allows user specify data attributes (columns, datatypes, etc) 1 table @ time, storing attributes independantly of application. dbase iii , paradox examples of kind of database in cp/m , ms-dos environments, , original filemaker mac o/s example.

a relational database takes "flat file" approach several logical steps further, allowing user specify information multiple tables , relationships between tables, , allowing more declarative control on rules data in tables must obey.

database systems mechanisms mediate between file systems , api based on rdbms principles. without getting detail specific sets of rules make rdbms, can these provide way organize , access information stored in files. noticeable features of databases compared raw file-systems structure , indexing.
