Brief details on Database Management Systems
86 viewsA Database Management System facilitates with a data storage system, data retrieval and data execution processes in an efficient way. Be it in web development service or an application development process, DBMS packages take the major pie in the project.
In a DBMS, data is stored using complex data structures, but the user only gets an abstract view of it. The different levels of a DBMS are:
* Physical level– For defining the architecture and the data structures
* Logical level – Describes data types and various relationships
* View level – Gives the required view to the user
The database Schema or the overall structure of the database specifies data types, relationships, consistency rules and data semantics for the data stored in the database.
The main categories or models of Database Management systems are:
Hierarchical model
In this database model, data is organized in a tree-like structure. The structure maintains a hierarchy using parent-child relationship (a parent with many children, but a child with only one parent) to manage the data and records are connected through upward or downward links.
Network model
In the network model, data is represented by links and records. The network database is based on the concept of many-to-many relationships with no limit on immediate child or parent node for a given occurrence of records.
Relational model
In this model, the database designer formulates a logical and consistent representation of information using declared constraints known as logical schema. Relational models are widely used in web site development service or in application development.
Object model
This DBMS model (also known as ODBMS) is based on the popular Object-Oriented paradigm, where the concept of application development (such as polymorphism) is merged with database architecture.
