A Business Object is a layer within a multi-tiered application, which functions as an interface between the business logic and data access layers. In an object-oriented (OO) system, objects are classes of data structures that are used to store, retrieve and manipulate different types of information such as data, formulas, or objects that can be linked to one another through inheritance. This gives the programmer the freedom to create different types of objects and to program the behavior of these objects to perform various tasks. To illustrate how business objects can be used in an OO system, think of a telephone directory. In this directory, the names and addresses of telephone companies can be located. The data used here is retrieved from the database which contains the phone numbers of each company’s employees and it also has a list of their addresses. The business objects used here are a simple type of record or data structure which can store the names and addresses of the people associated with each of the companies.
One example of how business objects can be used in an OO system is when an office has to have its own network, or a phone directory that is constantly updating. With this type of application, there can only be one business objects which would contain information about the phone number, the address, and the name of the person who owns the number, along with other information about the phone owner such as age, gender and location. Another way that business objects can be used in an OO system is when it comes to a business application which allows its users to input text into the software. This type of application is called a data source application, and business objects will need to exist inside of the program to allow it to properly input text in a format that can be read by the application. For example, if a customer is entering the last name and the number of his order, a business object would be created inside of the application to make it easier for the customer to input the information.
As previously stated, different business objects can be created depending on the application that is being used. For example, an application which allows its users to input a phone number can
include different types of business objects that contains addresses, names and phone numbers. Similarly, an application which allows its users to input a restaurant menu can include different
types of business objects to make the process of searching a restaurant menu much easier. These types of business objects can also be used in other applications such as software which generates reports. These reports are generally more complicated, as they need to contain a lot of information which may not be stored on the computer screen, but which will still need to be reported in.
Another application in which business objects can be used is the creation of user interface tools. Such tools may not need to be installed in the application itself, but they do need to exist within the application in order for them to properly be used. There are many types of business objects, and it will be up to the developer to find the one that will work best for the application. From the above information, you can see that business objects can be used extensively in an application.
The different types of business objects that exist within an application will depend on the type of data that needs to be stored within the application. Therefore, it would be a good idea for the
application developer to find the business objects which are most suited for the type of data that needs to be stored. If the data is very complex, then it would be beneficial to create a business object which has a more complex structure.
A good way to use business objects is to help a business application to better organize the data which is stored within it. In other words, an application which allows its users to enter data into a
form, or to select the kind of information that they want to enter into a form could benefit from having business objects which provide different ways to organize the data which is entered into the form. Many businesses which need to enter data into a database could also benefit from having business objects that allow the users to enter a particular number of fields. These fields could be
entered by entering a particular format, such as date or price or both. These fields would need to be entered in a particular way so that the system would know which fields to keep in the database.
