Improving the Accuracy of Early Software Size Estimation Using Analysis-to-Design Adjustment Factors (ADAFs)

Early software size estimation is a challenging task since limited information is available at the time of project inception. Additional information, however, is gradually added as development progresses. The goal of this research is to quantitatively capture the impact on early software size estimation of this additional information introduced especially when transitioning from the analysis phase to the design phase by comparing the analysis class diagram (ACD) and the design class diagram (DCD). We introduce a new class of metrics called analysis-to-design adjustment factors (ADAFs) to accomplish this goal. ADAFs are calculated for four different class diagram metrics - number of classes (NOC), number of attributes (NOA), number of methods (NOM), and number of relationships (NOR) - used in different class diagram-based software size estimation models. We use practical, theoretical, and empirical validation methods to evaluate the applicability of these ADAFs. To assess the utility of these ADAFs in early software size estimation, we compare the accuracy of existing early software size estimation models before and after the application of ADAFs. Results indicate a marked improvement in the accuracy of these models after the application of ADAFs. Furthermore, regression-based models employing problem domain metrics have also been built to predict these ADAFs. All of these models are statistically significant (p-values <; 0.05) with R <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> values between 0.42 and 0.88.

PERANCANGAN E-REPORT FINANCIAL SYSTEM BERBASIS WEB (STUDI KASUS : TOKO KRIPIK BALADO MAHKOTA)

Tujuan artikel ini adalah untuk merancang e-report financial system berbasis web yang akan diterapkan pada toko Kripik Balado Mahkota baik itu laporan penjualan, pembelian serta laba rugi, maupun transaksi jual beli antar supplier dan antar pembeli toko. Metode perancangan yang digunakan dalam sistem e-report financial yaitu pemakaian teknik arsitektur MVC (Model, View and Controller), dipadukan dengan menggunakan Framework Yii2 dan PHP, dengan media penyimpanan dengan database tools MySQL, dan model perancangan UML use case, activity diagram serta class diagram. Hasil dari perancangan e-report financial ini adalah tersedianya laporan yang bersifat elektronik, mudah diakses dimanapun dan kapanpun, dan juga meminimalisir data yang rancu dan tumpang tindih. Maka perancangan e-report financial ini mempermudah dalam pembuatan laporan dengan model perancangan, metode perancangan dan media yang mendukung dan di terapkan dalam sistem e-report financial.

MODEL SISTEM INFORMASI PEMBUKUAN UNTUK MONITORING TRANSAKSI KOPERASI DALAM MENDUKUNG PERHITUNGAN SISA HASIL USAHA

Cooperatives function to build and develop the potential economic capacity of members to improve economic and social welfare. Cooperatives are established aiming to realize the welfare of members in particular and the community at large and participate in building the national economic order in order to create an advanced, just and prosperous society based on Pancasila and the 1945 Constitution. Cooperatives organize several types of businesses such as savings and loans, all-round shops there and general trade. In running the business, the cooperative conducts bookkeeping to find out the profit / loss of the cooperative and the amount of the remaining business results that are fair and comparable to the amount of business services of each member. In the bookkeeping process there were often several problems such as, not well recorded every small and routine transaction, there were miscalculation caused by human error, the slow process of calculating the remaining business results which caused delays in making the report. To overcome this, it is necessary to design a bookkeeping information system model in the form of use case diagrams as a design model and class diagram as a database model and system application as a form of implementation, so that it isable to create a bookkeeping information system for monitoring cooperative transactions in supporting the calculation of the remaining results business effectively, efficiently, quickly and accurately.

A Unified Modeling Language-Based Design And Application For A Library Management Information System

Abstract This paper firstly introduces the main content of the Unified Modeling Language (UML) and proves that it can transmit information among the users, the developers, the designers and the managers efficiently, which improves their collaboration capabilities and greatly increases the degree of industrialization in software development projects. Secondly, a library management system development and design is carried out, based on UML modeling mechanism to analyze a simple library management system. Thirdly, a demand analysis mode of the management system is built with the help of a case diagram and an analysis diagram after analysis of a simple library management system, using UML modeling mechanism. Then a book lending management subsystem has been designed in the library management system by a design class diagram and a sequence diagram. The design process indicates that as a modeling language of software engineering, UML has a very good application prospect.

Pembuatan Sistem Informasi dengan Analisis dan Perancangan Berorientasi Objek

To generate an information system which is in accordance with the needs of company requires an analysis of business processes by observing the running system. Solutions for problems found when doing the business are observed using the systems approach. Object-oriented analysis and design is a method currently used to build an information system. The system development with "Object Oriented Analysis &amp; Design (OOAD)" method stated by Satzinger includes making activity diagram, event table, class diagram, usecase diagrams, usecase description, state chart diagram, deployment and software architecture, first-cut design class diagram, simple sequence diagram (SSD), the sequence diagram (first-cut, view layer, data access layer), communication diagram, updated design class diagram, package diagram, persistent object, user interface. The result obtained after performing all phases is an information system that fits the company needs which is expected to improve the performance and effectiveness in business processes and also support the company's business goals.

Analysis of business processes by observing the existing system is the main issue to produce information systems according to the needs of the company. Any search of problem solutions when doing business process is performed by a system approach. Object Oriented Analysis and Design (OOAD) is one of the methods currently used to build information systems. The method includes the building of activity diagrams, event table, class diagram, usecase diagrams, usecase description, state chart diagrams, deployment and software architecture, first-cut design class diagram, simple sequence diagram (SSD), sequence diagram (first-cut, view layer, data access layer), communication diagram, updated design class diagram, package diagram, persistent object, and user interface. The results obtained after performing all phases of the method is an information system based on the needs of companies that is expected to improve the performance and effectiveness of the company's business processes and support the business goals.

Using UML as Front-End for PLC Program Design

To minimize the influence of experiential factor and guarantee the software quality from the design phase, with the aid of unified modeling language (UML), an object-oriented design method for PLC program is presented. With UML as design tool, class diagram and state machine diagram are chosen respectively to describe the static structure and dynamic behavior of the PLC based control system, and PLC ladder diagram is acquired from state machine diagram subsequently. With the combination of object-oriented technology, UML and classic PLC design technology, the software reliability of PLC based control system is promoted, and the application area of object-oriented technology and UML is extended.
