5 Initial Design Report 5 1. INTRODUCTION This document includes the initial design strategies, overall sstem architecture and data architecture for SENTral which is Siemens EC Human Resources Management Sstem. There are sstem overview, design considerations, data designs, sstem architecture, user interface designs, libraries and tools which will be used in project and time planning of the project Problem Definition In toda s business life, companies use a lot of software programs. Enterprise Resource Planning software programs are one of the most used software sstems in companies different departments. Siemens EC uses also an ERP software which is human resources management sstem based on an in-house developed framework. However, this sstem contains some disadvantages and does not provide needs of compan and user requirements. The main disadvantage of used sstem in Siemens is that the sstem is not an open source platform. Thus, there is a need for migration of the old sstem to a new open source platform. Another deficienc of currentl used sstem is being old and not to serve completel needs of the departments and emploees of the compan. Hence, it should be replaced with a new sstem which supports the new requirements. According to all these lacks and disadvantages, there occurs that Siemens should have a new and an open source ERP sstem. So, we will work on a new human resources management sstem which will solve these problems. In addition, another senior design project group InnovaSoft will work on this project. There are three specific modules to be developed. The modules are master data, annual leaves and training modules. Our group concentrates on annual leaves and training modules and notification mechanism of the entire project. Other parts of the project such as master data, authentication and authorization, will be developed b InnovaSoft. The old software sstem used in Siemens EC does not have a dnamic structure. In addition, it is ver difficult to upgrade the sstem and to add new modules or functions. Thus, our project will have a dnamic structure to overcome these problems. There are about 200 emploees in the compan, so it is ver hard to manage annual leaves and trainings of emploees b manuall for HR department. Also, it is not a ver useful method for planning of resources and getting reports about emploees.
6 Initial Design Report 6 Also, the are ver important issues for managers to know information of emploees in their department and to get reports about emploees. Hence, the new sstem can be a solution for that problem. For emploees, there are a lot of procedures for getting an annual leave and attending training. All these procedures take so man times. In addition, to see of their information about annual leaves and training is ver important for planning their future requests and rights. Thus, in order to overcome all these problems there is a need of a contemporar software sstem for Siemens EC. B using this sstem, all processes and procedures can be done on a network, such as an intranet, in the compan. Also, the SENTral will contribute to compan for managing emploees and for planning of future of compan Purpose The aim of this document is providing a description of the software product in order to give the developers a guidance of the architecture of the software. It also serves the purpose of making the functionalit clear to sstem designers Scope This document includes descriptions about the design of the SENTral. All components and functions of the sstem are introduced in this document. However, there are design descriptions for onl ALM and TM of the SENTral. Also, the document describes the database tables, entit relations between objects and architectural structure of the sstem as noted in SRS document. Thus, this document is a guideline for software developers of the SENTral project Overview At rest of this document, there are introduced sstem overview which provides a general description of the SENTral including its functionalit and matters related to the overall sstem and its design in chapter 2. In chapter 3, there are design considerations such as assumptions, dependencies, constraints, goals and guidelines. There are data descriptions and data dictionar at chapter 4 which is Data Design. In chapter 5, there is sstem architecture of the SENTral. The user interface design is at the chapter 6. The libraries and tools will be used in the project are at the chapter 7. There are time plannings for this and next term as gannt charts. And the last chapter is a brief conclusion of this document.

8 Initial Design Report 8      2. Sstem Overview Our project consists of two main parts, namel ALM (Annual Leave Module) and TM (Training Module). In these modules we have three roles. These roles are emploee, manager, HR manager. In Figure 2, there is a diagram for explanation of general sstem overview of the SENTral. In ALM of this project, emploees should be able to see their annual leaves, to plan their annual leaves, to quer about their annual leaves. Managers should be able to do all processes defined for emploee role and be able to see information about the annual leaves of emploees in their departments. Also, a manager should approve or disapprove an annual leave request done b an emploee. A manager should be able to quer about emploees annual leaves and to get reports about them. A HR manager should be able to do all functions and processes defined for emploee role and manager role. In addition, a HR manager should be able to get reports about all emploees in the compan. In TM of this project, emploees should be able to see the trainings that are open for them and the dates of these trainings. The are able to request to attend training, and also be able to see the trainings which the have been attended so far. In common with ALM, manager should be able to do all functions of the emploee role. Also he/she should be able to see the emploees trainings that are attended before. Manager can approve or disapprove the training requests of emploees. In the sstem an HR manager is able to do all processes defined for emploee and manager and additional to this he/she has an allowance to get reports about the trainings of the emploees. Actuall, this project is divided into two parts. Our responsibilities in this project are ALM and TM. Other part will be projected b another group but our modules will be

10 Initial Design Report Design Considerations 3.1. Design Assumptions, Dependencies and Constraints Time Constraints Our human resources management sstem (SENTral) manages to run requests of at most 200 hundreds users of Siemens Compan at the same time. For this purpose, sstem should able to access database and get information requested with 2-3 seconds latenc. Users connect to our sstem through intranet. Performance of our sstem depends on the speed of their local server Resources Constraints Siemens Compan has a database for human resources management sstem. The have been using this database for their old sstem. An big changes to database are not necessar for this project. However, some minor details can be added or removed according to compan s request Performance Constraints Poor performance of SENTral is not expected since number of users is not over two hundreds. Moreover, performance of the sstem is directl related to local server that compan using. Technical qualit of our implementation also affects the performance of SENTral Software Constraints The sstem will be implemented b using Java programming language. Usage of an open source Java framework is mandator for this project. It should be a web based sstem. Framework should be selected so that it answers needs of sstem and compan. Reliabilit of framework is essential in case of securit and performance. Database interacts with a SQL DBMS. JDBC will be used to provide appropriate connection between the sstem and the database. Database for this project is available in the compan and have been used in the previous human resources management sstem.
11 Initial Design Report Hardware Constraints The web application will be hosted on one of the servers of the compan and connecting one of the Microsoft SQL Database servers. The sstem is a web-based application and also it is a intranet sstem that is onl used b the emploee of the compan. The user must have an internet connection in order to access the sstem and to use application. Also users are required to have a modern web browser such as Mozilla Firefox, Internet Explorer or Google Chrome etc Design Goals and Guidelines Since the sstem will work on web services, it must prevent all attacks from the outside and onl authorized people must access the database. Also another major principle that the sstem must provide is reliabilit. People must rel on the sstem and the must use the sstem in confidence. Functionalit is another important issue that should be considered. We should keep module interfaces simple so that users can easil make use of them. Functions of sstem should be understandable and sufficient for our clients. 4. Data Design 4.1. Data Description We will keep the information about the data objects in a database management sstem whose name is Ms SQL. There is a database alread designed and used in the compan and we will use this database b making some changes such as adding or deleting some columns in the database tables. We have mainl 6 tables in the database. These tables are emploee table, used annual leaves table, leaves information table, excuse table, training table and participation table. We will use these tables for holding necessar information about emploees, annual leaves and trainings. Emploee annual leaves table, annual leave table and excuse table are onl reachable b ALM. Training table and participation table are onl reachable b TM. Emploee table is reachable b both of the modules. E-R diagram in the Figure 3 shows relationship between these six tables.

Data Schemas This section contains data models which will be used in the ALM and TM of the SENTral. Section includes also descriptions of data and relationships between them. There will be 6 tpes of objects in the sstem. These data objects are User, AnnualLeave, Training, Report, EvaluationForm and Database. If there occur a need for creating new classes for user tpes such as emploees, managers and HR managers, it can be inherited from the user object Data Objects User Object This object will be used to keep name, surname, user Id, department name, age, gender and arra of user tpes. User: userid, name, surname, departmentname, age, gender, usertpe AnnualLeave Object This object consists of ear of the leave, number of leave das to be able to use, start date of a leave, finish date of a leave and duration of a leave. AnnualLeave: leaveyear, numofleavedas, startdateofleave, finishdateofleave, durationofleave.
17 Initial Design Report Training Object This object holds to name of training, name of organization providing training, tpe of training, start date of training and finish date of training. Training: trainingname, organizationname, tpeoftraining, startdateoftraining, finishdateoftraining Report Object This object will be used to keep a User object arra, Training object arra, AnnualLeave object arra and tpe of the report. Report: User, Training, AnnualLeave, reporttpe EvaluationForm Object This object consists of a Training object arra, User object arra and evaluation questions arra. EvaluationForm: User, Training, evaluationquestions Database Object This object will be used to hold name of the DB, name of the DB host, name of the DB user, password of the DB, connection string of the DB and quer string for the DB operation. Database: dbname, dbhostname, dbusername, dbpassword, connectionstring, querstring Relationships All objects except for Database object are associated with each others. Implementations and methods of different objects are required other objects attributes. A user object can create an annual object, training object, report object or an evaluation form object. Also, report object and evaluation form object consist of user object arra and training object arra. In addition, report object has annual leave object arra. Other 5 objects are not directl associated with database object. Database object will be used for accessing the DB and quering on it. This object will be created in methods of other objects.

25 Initial Design Report Sstem Architecture 5.1. Architectural Design The architectural design of our project consists of five main components. The components are the sstem database, sstem server and three sstem modules called Master Data module, Annual Leave module and Training module. In Figure 22, there is a diagram for architectural design of our project. Although there are three modules in the project, we will develop onl Annual Leave and Training modules. Our project has MVC design pattern architecture. Thus, in view structure, user interfaces of modules are included and interact with user. Controller structure are responsible for business logic of project such as getting requests from view structure and sending responses to view, also getting and setting data in model structure. Model structure is responsible for data in the database of project. Each component has assigned to subcomponents. Sub components of sstem are latel explained in Chapter 7 in detailed. Sstem server component consists of three sub-components which are Controller, Reporting Component and Auto-Mailing component. The role of sstem server is managing business logic of the SENtral. The sstem server is responsible to carring out requests of man clients simultaneousl. It also plas role in accessing to database sstem. The database component has role to store data in the sstem. An change or access to database is able with the help of two modules.
26 Initial Design Report 26 Figure 22: Component Diagram 5.2. Description of Components Database Component Database component is essential component of our sstem. All other components depend on this core section. Data flow occurs through database and sstem runs regularl via sstem database. Our sstem modules are continuousl related to database during user operations. An changes in the sstem operated through sstem modules are saved in the sstem database.
27 Initial Design Report Processing Narrative for Database Responsibilit of database component is to store data of the sstem. The sstem modules get data that is needed from sstem database component. It also accepts an changes and access b modules within the sstem rule Interface Description for Database The interface of the component has the particular propert. This propert is called Data Interface which provides an interface to the sstem to carr data between the modules. All the data through the sstem will flow over this interface. It receives data requests through sstem modules as an input. Then it translates into SQL data tpes and processes them using Hibernate Database Processing Detail This component sees all the other modules as blackboxes. All other data communications is done over this module. In other words the modules cannot communicate with each other. The information that needs to be transmitted somewhere is hold in this core component. 1) The sstem database receives a request of data from sstem modules 2) It translates this request into SQL commands using Hibernate 3) After generating the SQL calls it creates a corresponding object 4) Created object is presented to the related sstem module
28 Initial Design Report Dnamic Behaviour of Database Figure 23: Sequence Diagram for Database component Server Component Sstem Server is the component which provides technical environment for modules to run. With the help of sstem server modules reach database and sstem server is the reason for modules to occur Processing Narrative for Server The sstem server is responsible to carring out requests of man clients simultaneousl. In other words, it plas great role in the wa of accessing to database sstem. It is a nexus between requests and responses. It receives HTTP requests from the user side and delegate the requests to respect servlets to process the requests.
29 Initial Design Report Interface Description for Server In general server task can be considered as an input to the database. It receives data in form of HTTP protocols as an input. The required information is extracted and the necessar steps are taken into actions. It outputs HTTP responses and sends them to the clients via the intranet Server Processing Detail It works as follows: 1) It receives a request from clients through HTTP 2) It checks the validit of the request 3) It assigns the request according to the tpe of it 4) The result is sent to the user when it is processed Dnamic Behaviour of Server Figure 24: Sequence Diagram for Sstem Server component Annual Leave Module Component Annual Leave Module component is the central sstem made to meet expectations for planning annual leaves and reporting them. The main role of Annual Leave module is to answer expectations of users in the wa of leave requests.
30 Initial Design Report Processing Narrative for Annual Leave Module The responsibilit of this component is to keep track of annual leaves, allow a planning, coordination and approval mechanisms for annual leaves throughout the fiscal ear. This module gives possibilit to user to make leave requests or to approve and disapprove the requests Interface Description for Annual Leave Module The interface of component has a propert to provide users with leave requests and also with actions like printing leave paper Annual Leave Module Processing Detail This component appears after loginning to the sstem. Ever request made b emploee is noticed b the sstem and immediatel noted in database of the sstem. 1) The request made b user is accepted 2) It checks the validit of the request 3) The result is sent to the module when it is processed 4) The result is shown in the user interface to the user
31 Initial Design Report Dnamic Behaviour of Annual Leave Module Figure 25: Sequence Diagram for Annual Leave component Training Module Component Training Module is needed to generate a central application for the purpose of providing work and time savings for emploees and training coordinators. This module mainl serves for the emploees of the compan. Ever action taken in this module is notified b the database of the sstem Processing Narrative for Training Module This component is responsible for solving issues related with training requests of emploee. It provides appropriate options to the user Interface Description for Training Module. The interface of component has a propert to provide users with training requests. It receives training requests from the user as an input.
32 Initial Design Report Training Module Processing Detail This component appears after logging in to the sstem. Ever request b emploee is noticed b the database of the sstem. Each step of the processing detail is as follows: 1) The request made b user is accepted 2) It checks the validit of the request 3) The result is sent to the module when it is processed 4) The result is shown in the user interface to the user Dnamic Behaviour of Training Module Figure 26: Dnamic Behaviour for Training component 5.3. Design Rationale We separated the sstem into two major modules in order to keep the sstem simple, minimize cost and increase securit level. The presence of one application server minimizes cost in terms of mone and the cost of sstem distribution. All the necessar computations are carried out at the database of the sstem. Data storage is separate and alread available because we wanted to separate it completel from direct communication with the clients. Before concluding this sstem there is a term that should be noticed. The human resources management sstem was or is available for compan. However, there are
33 Initial Design Report 33 some critical issues concerning about this sstem. In order to move the sstem to open source, best practice frameworks together with enhanced user requirements that compan needs upgrade in the sstem. In other words, it is a different sstem that answers expectations of Siemens Compan. 6. USER INTERFACES 6.1. Overview of User Interface Since the sstem consists of two modules, user interfaces will be different in those two modes. In both modules there will be common home page interface for all sstem users and the will use these pages for login operation. After the login operation, users see annual leave page or training requests page on the screen.the login screen and the other screens for each module for each role (emploee, manager, HR manager) is described in the next part Screen Images, Objects and Actions In this part some of the screen images and their functionalities are described.
