For instance, for the use cases Create User and Delete User, one can have a single class called UserController, instead of two separate use case controllers. Alternatively a facade controller would be used; this applies when the object with responsibility for handling the event represents the overall system or a root object.
Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, [1] which can contain data and code: data in the form of fields (often known as attributes or properties), and code in the form of procedures (often known as methods).

Data field value = Jeffrey Tan The above description is a view of data as understood by a user e.g. a person working in Human Resource Department. The above structure can be seen in the hierarchical model, which is one way to organize data in a database. [2] In terms of data storage, data fields are made of bytes and these in turn are made up ...
Overview of a data-modeling context: Data model is based on Data, Data relationship, Data semantic and Data constraint. A data model provides the details of information to be stored, and is of primary use when the final product is the generation of computer software code for an application or the preparation of a functional specification to aid a computer software make-or-buy decision.
Fields may be stored in a random access file. [7] A file may be written to or read from in an arbitrary order. To accomplish the arbitrary access, the operating system provides a method to quickly seek around the file. [8] Once the disk head is positioned at the beginning of a record, each file field can be read into its corresponding memory field.
In object-oriented programming, classes can contain attributes and methods. An attribute in a relational database can be represented as a column or field. In computing, an attribute is a specification that defines a property of an object, element, or file. It may also refer to or set the specific value for a given instance of such.
In computing, an object-oriented user interface (OOUI) is a type of user interface based on an object-oriented programming metaphor, and describes most modern operating systems ("object-oriented operating systems") such as MacOS and Unix. In an OOUI, the user interacts explicitly with objects that represent entities in the domain that the ...
