What is a database model?

In the widest definition, all databases are the same in storing data and data can be manipulated or induced. At the same time, there is a defining aspect of each database called the database model. The database model is the data structure and the model determines how the data interact and how it is displayed. There are five main database models, although some database designers create model hybrids to meet the needs of entity that requires a database. These five models are a flat model, hierarchical model, network model, relational model and object model.

Flat database model is the simplest of all databases. It is used when all database values ​​are similar and there is only a small amount of information to be stored. This diagram shows all data in a table or table, each row is a different record. Usually, for the database to be secured, each line will have a different password.

At the beginning of the development of databases, the hierarchical database model was one of the most popular and inThis database is still commonly used. In this database, each record has a hierarchy, from wide records to specific. This database is compiled with the relationship of a parental child, which means that a wide record-parent-is open to reveal specific-networks. The network database model is almost the same as the hierarchical model, with the exception of several parents, it can connect to the same child, allowing this model to create more complex interactions.

The

database model of objects concerns the creation of tables in the tables to prevent the database. For example, in most other database models, each record will have to be coded separately. In the object model, you can make the main table and each record in this table may contain other similar records. This allows for similar records to be encapsulated separately, which makes the organization's maintenance easier.

Since its foundation in the age of 70.Faste data ways that are easy to understand and are easily called. As the name suggests, this model mainly deals with the relationship between data sets and finds common features between records that make it easier for administrators to call similar data. These databases also use several different tables at a time, and each record can have a key that separates it and allows more complicated relationships.
