Inventory Information System Using LIFO Method

At one of the goods distribution organizations in Bandung, manual recording problems such as data mistakes, delayed information, and challenges with inventory analysis must be addressed, and here is where the inventory information system comes in. An inventory system must be implemented to improve accuracy and efficiency in inventory management. With the correct technology, the business can reduce data errors, speed up information access, do practical inventory analysis, and increase productivity when taking and maintaining inventory. This study develops a web-based inventory information system using the MySQL database from the XAMPP application, the Laravel framework, and the PHP programming language. Representative data modeling and the creation of user-friendly interfaces are critical components of the design focus, which also considers proper technology selection. In order to better understand user needs and provide answers, system design will use the Object-Oriented Software Engineering (OOSE) model. In order to help with more precise decision-making in inventory management, the Last-In-First-Out (LIFO) method is used in inventory data analysis. Inventory may be easily monitored by using LIFO to offer information on nearly depleted stock and out-of-stock items. One of the Bandung-based goods delivery companies has seen notable gains due to the adoption of the new inventory system. With this new technology, the business may get past problems with manual recording, like data inaccuracies, delayed information, and challenges with inventory analysis. By streamlining the recording process and facilitating more efficient inventory management, this system facilitates better access to inventory information and increases the efficiency of inventory management. In summary, using an inventory system is an excellent way to get around problems with manual goods recording. This solution increases inventory management efficiency and speeds up the recording process for one of the Bandung-based commodities delivery enterprises. Its deployment offers significant advantages, improving the company's overall operating performance and facilitating more effective inventory management.

Web-Based Sales Information System in One of The Cash Shops Using the Business to Customer Method

Science and information technology's rapid and sophisticated progress motivates humans to generate novel solutions that facilitate easy and speedy information acquisition. Consumer behavior has experienced a substantial transformation in the present digital age. Many people opt for Internet purchasing due to the ease, accessibility, and flexibility it provides. The fashion industry is not immune to this phenomenon, as internet retailers are gaining popularity as a preferred method for buying clothing and accessories. Online retailers offer advantages such as convenient access to product catalogs, the ability to purchase at any time and from any location, and a broader selection of options. This offers a substantial opportunity for fashion retailers to access a larger pool of potential customers and enhance their market dominance. The sales process in a particular fashion store now depends on a traditional system involving direct transactions at the physical store and maintaining sales data through paper documents. This technique encounters multiple impediments that must be surmounted. A significant challenge is the limited accessibility to clients beyond the geographical confines of the physical business. In addition, using paper documents to manage sales data also needs to be improved in efficiency and accuracy. The method is laborious and prone to human errors. As inferred from the background description, the author's objective is to develop a web-based sales information system for a fashion retailer utilizing the business-to-customer approach. This system will streamline the sales process and aid in managing sales data, encompassing product data, customer data, and transactions. The system development will utilize the PHP programming language and the MySQL database, widely employed in online development. The research methodologies encompass literature review, observation, and interviews. The chosen approach for system development is Object-Oriented Software Engineering (OOSE), which utilizes Unified Modeling Language (UML) for system modeling. This includes using various diagrams such as use case, activity, sequence, and class diagrams. Hence, the sales information system is anticipated to offer a more efficient resolution for carrying out sales procedures and enhancing data administration promptly, safely, and precisely. Implementing this strategy will enable the fashion store to expand its consumer base, particularly among individuals located beyond the geographical reach of the actual store, thereby improving overall business performance.

Design and evaluation of a collaborative UML modeling environment in virtual reality.

Modeling is a key activity in conceptual design and system design. Through collaborative modeling, end-users, stakeholders, experts, and entrepreneurs are able to create a shared understanding of a system representation. While the Unified Modeling Language (UML) is one of the major conceptual modeling languages in object-oriented software engineering, more and more concerns arise from the modeling quality of UML and its tool-support. Among them, the limitation of the two-dimensional presentation of its notations and lack of natural collaborative modeling tools are reported to be significant. In this paper, we explore the potential of using virtual reality (VR) technology for collaborative UML software design by comparing it with classical collaborative software design using conventional devices (desktop PC/laptop). For this purpose, we have developed a VR modeling environment that offers a natural collaborative modeling experience for UML Class Diagrams. Based on a user study with 24 participants, we have compared collaborative VR modeling with conventional modeling with regard to efficiency, effectiveness, and user satisfaction. Results show that the use of VR has some disadvantages concerning efficiency and effectiveness, but the user's fun, the feeling of being in the same room with a remote collaborator, and the naturalness of collaboration were increased.

Distance learning quality assessment of universities based on interval monotonic decision tree algorithm

The standards and procedures of teaching quality evaluation systems improved with the continuous advancement of Video Internet of Things (VIoT) in the distance learning reform across colleges and universities. The old teaching quality rating approach is no longer adequate. We explore the idea of developing and designing the quality evaluation system for distance learning in this paper using an efficient interval monotonic decision tree algorithm. We use relational database technology to centralize the management of various knowledge elements in the VIoT system. It enables the VIoT system to perform operations like browse, delete, add, and modify knowledge that enhances knowledge transparency for designers and introduces intervals. We designed the interval monotonic decision tree algorithm with an evaluation domain partitioned. The proposed method creates the decision evaluation matrix, summarizes it, and obtains the evaluation conclusion using the complete weighting technique. Aspects of the system logic are tested using object-oriented software engineering, object-oriented design and analysis of requirements, and black-box testing.

Space Management on Campus of a Mobile BIM-based Augmented Reality System

Over the past decade, building information modeling (BIM) has gained a foothold in the construction sector. However, as digital data generated in the virtual space of a computer environment, BIM-based data have an inherent limitation in their application efficacy under field conditions. To overcome this, the present study employs augmented reality (AR) to reduce the discrepancy between the digital data generated in virtual spaces and real-world conditions. We assessed the potential applicability of an AR-based interface by analyzing existing examples of Apple, Google, and Facebook, which reflect the recent developments of technologies focusing on user experience. We then proceeded with an AR study, restricting the scope of application to a mobile environment in which an efficient information transmission between a digital model and real life can take place. Object-oriented software engineering was employed to ensure an efficient implementation of a BIM-based AR system for campus space management (CSM) in a mobile environment. Finally, we conducted a module test to check the reliability of the CSM method by using an AR-based mobile system with a prototype of the model used in university campuses, and extracted and itemized the supplementary requirements for CSM by using BIM tools for running AR applications.

FueL: Representing function structure and function dependencies with a UML profile for function modeling

Modeling functions is a key aspect of artifact design, including software engineering and business systems modeling, but it is likewise of fundamental importance in natural systems modeling, for example in modeling biological organisms. The Unified Modeling Language (UML), which originated from object-oriented software engineering, is nowadays a de facto standard for conceptual modeling and its current applications go far beyond software engineering. The paper investigates first to what extent UML is suited for modeling functions. We survey various approaches to function modeling with UML and identify their limitations. Based on the conducted analysis, we introduce a UML profile for function modeling, called the Function Modeling Language (FueL). FueL enables the modeling of the structure of functions, of relations between functions, such as function decomposition, as well as of function ascription, i.e., of relations linking functions with other types of entities. The main application field that we considered while developing FueL is bioinformatics. Nonetheless, the presented profile is domain-independent and is capable of modeling cross-domain systems. The profile has been tested on fragments of the Molecular Function Ontology, a sub-ontology of the Gene Ontology. In this connection the paper further demonstrates that the applications of FueL transcend the construction of new models, by showing how the profile aids restructuring and refactoring existing models.
