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.Know More
Object-oriented modeling uses objects that contain stored values found within an object. It is the process of designing and preparing what the model's code looks like. Modeling techniques are implemented during construction. The three phases of object-oriented modeling are analysis, design and implementation. The main focus during the first stages of development is on the external details of the system. The primary focus shifts during the later stages of development onto understanding how the system functions. As the development process advances, the model becomes more detailed.
In a relational model, data is stored in tables. Each table includes rows, columns, a header and a body. The relational model also uses keys, which are specifically designated columns, to order or relate data in one table to data in other tables. Rules or integrity constraints are designated by the relational model to ensure data integrity. Normalization is also used to ensure data is stored more efficiently.Learn more about Computer Programming
Object-oriented programming is a style of programming that is recyclable and easy to develop and maintain. A single object, created from a class or prototype, can be reused for multiple purposes. One advantage available to object-oriented programmers is the use of encapsulation, which prevents accidental manipulation by allowing access restrictions to be set on parts of an object. Since object-oriented code is easy to navigate, updates are much quicker.Full Answer >
Computer databases can store a large amount of information at a small cost. They can also retrieve information quickly. Computer programs can access information stored in databases to create analytical data in a short period of time.Full Answer >
A database query is designed to retrieve specific results from a database. The query is formulated by the user following predefined formats. After searching through the data, information pertinent to the query is filtered out of the data collection and reported to the user.Full Answer >
The primary advantage of including a GUI with software is that it makes it easier for the vast majority of users to learn and use the application. The main disadvantages are that it uses more system resources, thus degrading the overall performance of the software. Additionally, GUIs often provide the user with less granular control over the operations.Full Answer >
