The relational database model eliminates duplicate data and allows easy access to information. It also makes it easier to update data.Know More
The relational database model is a collection of stored data that is organized into multiple tables linked to one another using key fields. One row in a table can reference another row in a different table. This makes the model a systematic way of managing data.
While a relational database model can be harder to design than a flat file database that uses only a single table of data, its advantages make it more flexible, according to Indiana University. Users need to enter each piece of data only once, which minimizes the size of the database as well as the likelihood of mistakes. Each line of data, or record, has a unique identifier that serves as a relational key that makes it easy to locate data when a user needs to access a record.
Another significant advantage is that multiple users can access the data with individual permissions that protect the security of the database. They can each view the same data set in the most appropriate way for their needs. It is also easy to access the data programmatically using software applications.Learn more about Software
Some advantages of a database approach include consistent information, flexibility, easy management of data security and privacy and a reduced application development time. Simply put, a database is defined as a collection of related information. Companies use a Database Management System, or DBMS, to assist in data organization.Full Answer >
An object-oriented model uses objects containing stored values to unite the application and database development, while a relational model uses relations to construct data. The rational model is used to create grid-like mathematical structures while the object-oriented model is used to transform data into a unified data model.Full Answer >
The major advantage of the incremental model is that it generates a working application faster and earlier during the software development life cycle; however, problems can occur with iteration phases if not implemented correctly, and developmental costs can be high. For it to be successful, the entire system must be clearly defined before it is broken down and developed in incremental models.Full Answer >
