“…2) takes into account the peculiarities of the aggregation relation-ship between software classes. A peculiarity of the queue, in contrast to known solutions [4,[7][8][9], is the use of the model of the resource class and customer classes. This makes it possible to manage the provision of services to client classes in the absence of conflicts.…”

“…Work [4] deals with the issue of identification and analysis of the effectiveness of class attributes. However, the research is only concerned with attributes whose selection is consistent with the purpose of creating the class, while with "re-use" the purpose of applying the class may be slightly altered.…”

“…When introducing the concept of the main class and the resource class, the composition assumes that the main class creates the resource class and fully controls it, while in the case of aggregation, the object of the resource class is not necessarily created by the main class. The main class can receive a reference to the object of the resource class [4] and, therefore, there is no full control over its attributes. In this case, there is a need to share resources, that is, a transition to the task of mass service [5] and the need to organize a queue for the main classes, which, according to their new role, can be termed client classes.…”

The object of research is the implementation of relations between software classes. It is shown that when implementing the aggregation relationship between classes, errors may occur if more than one client class is found. Class interaction errors can be caused by management of resource class attributes by one of the client classes in a way that is unacceptable to another client class due to invalid attribute values, state changes, method blocking, etc. To solve the problem, a special organization of the queue for client classes is proposed. A feature of the queue is the use of models of client classes and resource class. The model of a resource class provides an idea about its resources (attributes and methods) and how they are used. The client class model shows how much of these resources will be used by the client and how this will be done. This organization of the queue makes it possible to provide resources to the next client class only after checking its compatibility with active client classes. In general, client classes have different types, and this complicates the organization of the queue. Therefore, it is proposed to make them derived from the base class, which defines the interface for the queue. Similarly, the problem of the interaction of the class-resource with the queue is solved. The proposed base class for the resource class also provides the necessary queue interface. Software was developed that automates the process of converting classes: analysis of a resource class, determination of resource needs from client classes, construction of base classes. After the conversion is completed, the queue functions are supported. The study results verification showed a reduction in the time for converting classes by about three times, and the waiting time for access to resources during the work of the queue – at least two times

“…Automatic change detection can simplify programming and design, so producing more reliable systems with less energy. Zeynab (2015) researched and published a comprehensive literature review over relationships among objects and also identified three basic types of relationships, including generalization or specialization, aggregation and association. (Weixin et al, 2021) presented a new statically typed modular programming approach called Compositional Programming.…”

Programming computers has been a herculean task for most programmers especially when codes grow into complex and larger software systems with multiple subprograms. Object Oriented Programming (OOP) has reduced the difficulty in the development of elegant and scalable software by presenting robust concepts such as composition, inheritance and aggregation. All these concepts have enormous assistance to the software developer in code reuse. Also these techniques can be used to build applications which can be delivered to customers in a record time. In this research a critical study, review and implementation of software building and enhancement using aggregation and inheritance. A module is built with attributes defining it properties and methods its characteristics. Incrementally more modules were added to the previous modules using either aggregation or inheritance technique. This incremental approach has proven tremendous success in software development. This as buttressed by many software development theories have shown that: software is built not manufactured; software is a collection of programs with functions and attributes based on its enhancement, also incremental software development which involves building systems from sub-systems gives a better understanding of software development process. Also the process of writing bug-free programs can be achieved with lesser difficulty which can be achieved when programs are built using modular or incremental software development approach, which employs mostly aggregation while moderately using inheritance only if all the properties and methods of those modules are needed wholesomely in classes. The result from the research will help programmers to enhance codes with much mastery.
