An overview of the user interface architecture, focusing on the presentation, service, application, domain, and data layers. The presentation layer is responsible for user interaction and runs in the user's web browser. The service layer modulates features and interacts with external APIs. The application layer accepts user requests, processes them, and determines data access routes. The domain layer contains business logic and models. The data layer provides centralized access to the database and external APIs. The document also discusses the MVC model and architectural goals and constraints.

Element Presentation Layer The presentation layer contains the user functionality responsible for managing user interaction with the system and provide a common bridge into the core business logic. It will be composed of HTML, CSS, JAVA, and other related files that will run in the user’s web browser of choice. The main goal of this layer is to provide everything the user needs to complete their tasks in the system. Service Layer Its the second layer when service to other application as well as implementing clients directly a common approach is to use services The service layer is in charge of modulating different features (services) of the application. Certain features, such as reporting, require access to external APIs; the service layer will being in charge of interacting with those external APIs. Application Layer This,layer, also called Business,Logic,or Domain,Logic,or,Application Layer, accepts user requests from the browser, processes them, and determines the routes through which the data will be accessed. The workflows by which the data and requests travel through the back end are encoded in a business,layer. This includes App. Controller,App. Service,Event Listener. Domain Layer This is the layer that contains all business logic, the Entities, Events and any other object type that contains Business Logic. This is the heart of the system. This is where your business rules and logic resides, your domain models are defined. It includes entities,collection,value object,domain services,domain Events. Data The data access layer provides a centralized location for all calls into the database, and thus makes it easier to port the application to other database systems. All persistent information and any external API integration make
Toolkit) for Ada, Eclipse CDT for C/C++, and Eclipse PDT for PHP. Eclipse is an open source community, whose projects are focused on building an open development platform comprised of extensible frameworks, tools and run times for building, deploying and managing software across the life cycle. The Eclipse community is a not-for profit, corporation who are members of the Eclipse community hosts the Eclipse projects and helps develop an open source community and a world of complementary products and services. MySQL Administrator or Microsoft SQL Server will be used to create, manage, and optimize the person database module. MySQL Administrator MySQL is a relational database management system (RDBMS) that runs as a server providing multi-user access to a number of databases. The SQL phrase stands for Structured Query Language. The MySQL development platform has made its source code available under the terms of use of the GNU General Public License. Open source free-software projects use MySQL if it is required a full-featured database management system. Several paid editions are available for commercial use, and offer additional functionality. MySQL is also used in May high-profile, large-scale World Wide Web products, including Wikipedia, Google, Facebook, and Twitter. MicrosoftSQLServer Microsoft SQL Server is a relational database server, developed by Microsoft. It is a software product whose primary function is to store and retrieve data as requested by other software applications, be it those on the same computer or those running on another computer across a network (including the Internet). There are at least a dozen different editions of Microsoft SQL Server aimed at different audiences and for different workloads (ranging from small applications that store and retrieve data on the same computer, to millions of users and computers that access huge amounts of data from the Internet at the same time). Constraints The constraints there is no limitation in the operating system in which HRMS will work. However, the HRMS system and the database will work on a server that needs to be always online. Users can access the system with any internet browser
Presentation Layer – This layer is used to implement the User Interface to communicate between the User and the Application. The presentation layer consists of the forms, presentation logic, and reports and implemented using CSS, Smarty, DHTMLX, XML, HTML, and PhP. Security System Layer – Used to provide security and access control services to all applications. And supports Granular Access Control, and implemented using PhP. Application Business Objects Layer – This layer is used to implement the business logic of each application. Each application has its business logic classes implemented using PhP. Workflow Services Layer – A set of workflow classes that are used to implement workflow services, which are use by all applications for review and approval and associated processes and tasks. Database Access Layer – Used to provide database access to all applications and supports multiple databases access
