II. LITERATURE REVIEW

A. Literature Review

1) “Chowdhurry, S., Demor´e, B., De Santis, O., Dollman, J., Dutcher, S., Finkelstein, Klepser, M. (2023). A systematic literature review and meta- analysis of community pharmacist-led interventions to optimise the use of antibiotics. Journal of Pharmacy Practice, 15(3), 1-18.”

This systematic review and meta-analysis assess the effects of community pharmacistled interventions to optimize the use of antibiotics.

The review emphasizes the importance of alternative strategies, such as audit and feedback, in the community pharmacy setting. It suggests that more attention should be paid to different implementation strategies, with special attention to patient needs, to improve interventions and better meet the needs of patients.

 

2) “Chen, Y., Li, X.and Zhang, Y. (2021). The impact of mobile health applications on medication adherence: A systematic review and metaanalysis. Journal of Telemedicine and Telecare, 27(1), 13-23.”

This systematic review and meta-analysis assess the impact of mobile health applications on medication adherence. The review highlights the potential of mobile health applications to improve medication adherence, particularly in chronic disease management. It suggests that mobile health applications can provide personalized medication reminders, education, and support, which can lead to improved medication adherence and better health outcomes

 

B. Existing Systems

1. Traditional Inventory Management Systems: Many pharmacies likely rely on manual or semi-automated inventory management systems, which may involve tracking inventory using spreadsheets or basic software. These systems often lack real-time insights and may be prone to errors.
2. Manual Expiration Date Tracking: Pharmacists may manually track expiration dates of medications, which can be time-consuming and error-prone. This manual process may result in missed expiration dates and the disposal of expired medications, impacting both patient safety and operational efficiency.
3. Stock Level Monitoring: Pharmacies likely have systems in place to monitor stock levels and reorder medications as needed. However, these systems may not be optimized for real-time monitoring or may lack customization options to set optimal stock thresholds.
4. Barcode Scanning Systems: Certain pharmacies may utilize barcode scanning systems to track inventory movement and manage stock levels. However, these systems may not fully address the challenges associated with expiration date tracking and stock optimization.

To use the MedGuard app, users must first log in. Once logged in, they can access the Manage Medicine and Manage Pharmacy sections.

Here is a brief description of the flow of the System Architecture

1. The user logs in to the MedGuard app.
2. The app authenticates the user and retrieves their medication and pharmacy information from a central database.
3. The app displays the user’s medication and pharmacy information in the Manage Medicine and Manage Pharmacy sections.
4. The user can interact with the app to manage their medications and pharmacy information.
5. When the user is finished using the app, they can log out.

 

The system architecture is a three-tier architecture, which means that it is divided into three layers :

1. Presentation Layer: The presentation layer is the user interface of the app. It is what the user sees and interacts with when they use the app.
2. Application Layer: The application layer contains the logic of the app. It is responsible for processing user requests and retrieving and storing data from the database.
3. Data Layer: The data layer contains the database. It is responsible for storing and retrieving data

The three layers are loosely coupled, meaning that they can be changed or updated independently of each other. This makes the system architecture more flexible and easier to maintain.

B. Introduction to Language

1) Introduction to Java Programming Language

Java serves as the cornerstone of the MedGuard project, providing the foundation for crafting a robust and scalable Android application aimed at revolutionizing pharmacy inventory management. Developed by Sun Microsystems (now owned by Oracle Corporation), Java is a versatile and widely-used programming language known for its platform independence, object-oriented approach, and extensive ecosystem of libraries and frameworks.

• Platform Independence: Java’s ”write once, run anywhere” mantra is a defining feature that enables developers to write code once and execute it on any platform that supports Java. This platform independence is achieved through the Java Virtual Machine (JVM), which translates Java bytecode into machine-specific instructions at runtime.
• Object-Oriented Programming: Java follows an object-oriented programming (OOP) paradigm, emphasizing the use of classes and objects to model real-world entities and encapsulate data and behavior. This approach promotes code reusability, modularity, and maintainability, making it wellsuited for building complex and scalable applications like MedGuard.
• Rich Standard Library: Java boasts a comprehensive standard library that provides built-in support for various functionalities, such as input/output operations, networking, data structures, and multi threading. This rich library ecosystem simplifies common programming tasks and accelerates development without the need for third-party dependencies.
• Memory Management: Java’s automatic memory management system, facilitated by the Java Virtual Machine (JVM), relieves developers of the burden of manual memory allocation and deallocation. Java’s garbage collection mechanism automatically identifies and removes unused objects from memory, reducing the risk of memory leaks and improving application stability.
• Security: Java places a strong emphasis on security, with built-in features such as bytecode verification, sandboxing, and security managers to prevent unauthorized access and protect against malicious code execution. These security measures make Java a popular choice for developing secure and reliable applications in sensitive environments like healthcare.

 

2) Role in Project Implementation :

• Core Functionality : Java is used to implement the core functionality of MedGuard, including data management, user interface interaction, and business logic. Its object-oriented nature allows developers to organize code into reusable components, fostering maintainability and extensibility.
• Android Compatibility : Java is the official programming language for Android app development, supported by the Android Software Development Kit (SDK) and integrated development environment (IDE) such as Android Studio. By writing MedGuard in Java, we ensure compatibility with the Android platform and access to a wealth of Android-specific libraries and resources.
• Performance Optimization : Java’s efficient memory management and runtime performance optimizations contribute to the smooth operation of MedGuard on various Android devices. Java’s performance capabilities, combined with platform-specific optimizations provided by the Android runtime, ensure that MedGuard delivers a responsive and reliable user experience.

In summary, Java serves as the backbone of the MedGuard project, enabling the development of a powerful and user-friendly Android application for pharmacy inventory management. Its platform independence, object-oriented paradigm, rich standard library, and emphasis on security make it an ideal choice for building secure, scalable, and high-performance applications like MedGuard.

By dragging and dropping UI components onto a virtual phone screen, developers could quickly prototype and refine the app’s layout to ensure it was user-friendly and visually appealing.
• Built-In Emulator: Android Studio includes a built-in emulator that simulates the behavior of different Android devices. This emulator allowed developers to test the app on various screen sizes, resolutions, and Android versions without needing physical devices, enabling thorough testing and ensuring compatibility across a wide range of devices.
• Integrated Build System: Android Studio seamlessly integrated with Gradle, a powerful build automation tool, to automate the process of compiling, building, and deploying the app. This integration simplified the build process and ensured consistent, reliable builds, even as the project grew in complexity.
