Re: Data Base Management System
A Database is a collection of records. Database management systems are designed as the means of managing all the records. Database Management is a software system that uses a standard method and running queries with some of them designed for the oversight and proper control of databases. Types of Database Management Systems: There are four structural types of database management systems: -Hierarchical databases. -Network databases. -Relational databases. -Object-oriented databases For getting more information about types here I am attaching an attachment: Models A database model is a type of data model that determines the logical structure of a database and fundamentally determines in which manner data can be stored, organized, and manipulated. Common logical data models for databases include: -Navigational databases Hierarchical database model Network model Graph database -Relational model -Entity–relationship model Enhanced entity–relationship model -Object model -Document model -Entity–attribute–value model -Star schema An object-relational database combines the two related structures. Physical data models include: -Inverted index -Flat file Other models include: -Associative model -Multidimensional model -Array model -Multivalue model Specialized models are optimized for particular types of data: -XML database -Semantic model -Content store -Event store -Time series model |
