At the early stage of examination, these models argon exercised to show info processing in existing system. This data flow model consists of mixed nonations which denotes functional processing, passing of data between two functions and storing data at some level. Data flow models are the step by step delegation of data flow in sequence. Transformation of data takes place at apiece step in model while entering to next step. This vicissitude or processing steps are functions defined for particular activity or program. In this program functions data flow draws (DFDs) define software design. in that respect are number data flow diagrams modeling rules are followed such as 1) there should be in and out of data flow is needed for all pro cesses. 2) Incoming Data is modified by all processes and they should produce transformed new outgoing data 3) data store must be involved with wiz data flow module. 4) One of the data flow must involve one foreign entity. 5) data flow should have token(prenominal) one process attached to it .4.2 Data Flow DiagramIn data flow diagrams data flow in the system is re ease uped by graphical view. This graphical view can be used to represents any information or processing criteria in development of system. First step towards foundation of overall system is shown by DFD which can later expand. DFDs show data processing in each function. Data flow diagrams renders information round what should be input for each module and expected output afterward processing as well as how the data will enter and how it is passed and where it is stored. DFDs are sightly used to show information flow in the system. They wont show time required to complete the process or how processing can be done w hether serially or parallel.4.2.1 Physical DFDA physical data flow diagram (physical DFD) represents true(a) implementation of the system at the present DFD and required DFD can be designed as per future demands. Hence physical DFD can be designed in both forms in flowing position and one can build on future demands by customers. Physical DFDs describes set of data items included on each paper circulated in office and they describe truth about unique set of paper pieces that are stored together in filling cabinet. As it shows all information about data in all forms thus there is possibility of inclusion of references towards data that are redundant or copied the storage of data is implemented as tables that could be normalized or de-normalized relational database. Logical DFD work opposite to physical DFD in such a way that it tries to capture data flow aspects in system that is not copied or have redundancy.Context level data flow diagrams can be move practisizing it. They show interaction between external entities and system that are considered as data source and data sink. That could be helpful in drawing context diagrams. How this system interacts to external agents is designed naturally in terms of data flow between system boundaries. The context diagram denotes whole system as a single process and does not provide any information to internal organization.These context level diagrams are expanded next to generate level 1 flow diagram that represents gnomish detailed information about the system to be modeled. Level 1 system represents ts of wedge shape systems from which system is built that each process consists of more than one data flows which goes to external entity or comes from it and considering theses processes together forms one single system. Data stored from each module should be in order to perform its job and this defines the actual data moving from different parts of system. DFDs are important part of structured systems analysis and it is SSADM method. These diagrams provide information of system evolution in elemental word to the sponsor person or end user. DFDs provide information about operation of system will complete its task and implementation dilate about system.DFDs of old system can be compared with new proposed system to see the output and can be used for development of system with updates. A data flow diagram provides idea to end user about the change in systems output after giving data input at modules. System development can be shown through DFD model.There are different levels of data flow diagrams and designer should show partition of system into interchange systems, also the data flow between each module. In SDLC for analysis and design step DFDs are used. Data flow diagrams can be drawn by using various notations (Yourdon Coad, GaneSarson), that shows data stores, data flow, processes, and external agents. imageure 4.1Notations used in the Dataflow DiagramIn the above figure 4.1 the notation s used for cover data flow diagrams have shown. It indicated the control flow of project modules from starting to end. The following figures show each modules data flow diagram. As modules include 1) field of operations grid generator 2) Random population initialize 3) Applying algorithm. anatomy.4.2 Flow diagram of field of study grid generatorAs shown in the above fig 4.2 data flow diagram input values are passed that are latitude and longitude of each sharpen so that one area is selected. After that this transformation of data can takes place in the form of distance calculation. Hence the output will be calculated distance is divided into smaller grids.Fig. 4.3 Flow diagram of random population initializationA data flow diagram defines the data flow from one module to another module this can be illustrated in this system as shown in above fig 4.3. In this DFD the input comes from area grid generator in the partitioned form of area grid. In this module main function is to gene rate random population for each smaller grid. After the population generation for each grid random ATM machine is located.Fig. 4.4 Flow diagram for final ATM locatorIn the fig 4.4 DFD input taken from random population initializer module and one point crossover and mutation operation can be applied on them , once the fitness evaluation based on percentage of population is done.Fig 4.4 Flow diagram of ATM deployment with RGAC4.3 Sequence DiagramSequence diagram is a chart of sequence of message. They are called as interaction diagrams as they provide information about inter-process operation in order. Here object interactions are time specific. One scenario is built from objects and classes. The messages are exchanged sequentially between objects for perform particular task in the scenario. They are called as event scenarios or event diagrams because they are arranged in time sequence. Sequence diagrams consist of use shell realizations built from logical of system which is under i mplementation.In sequence diagrams various processes or objects that are running parallel are shown by tumid lines also called as lifelines and messages exchange is denoted by horizontal arrows, in orderly fashion based on time. This can be shown in terms of graphical view. If the vertical line is object it shows a role. It is compulsory to denote instance name, if it is blank it will consider it as anonymous or unnamed instance. Messages with horizontal arrows with message name on top of arrow show interaction. Synchronous calls represented by solid arrow, asynchronous messages are denoted with open arrow and reception message with dashed lines. If a sender sends message is synchronous then it must wait until message completes and invoke a subroutine. In asynchronous bear response is generated. Such kind of direct response with asynchronous message is seen in multithreaded applications and also implemented in message oriented middleware.Processes that are performed after respons e to message are shown with activation boxes or method call boxes. They are present on top of vertical lines and are opaque rectangle. bran-new activation boxes are shown if it indicates next level of processing and objects invoking functions on themselves use messages. Objects destroyed are shown with X on top of vertical lines and dashed lines are ceased drawn below.Following fig 4.5 shows sequence diagram of ATM deployment in terms of client innkeeper activity. Here Clients are user. Clients has to select initial area for study, hence first step is to enter the latitude and longitude of each location from which area is build from i.e. top, bottom, left and right corners of area. This data is stored in database and it is shown at server side for further operation. After this selection process this area is represented in terms of grids for studying smaller part of the area.For this purpose this grid is partitioned into sub grids. Now for this selected area subparts random initial ization population can be done and randomly ATM machines are placed. After evaluating the percentage of population of each grid, and applying algorithm for taking more accurate points, for highly dense areas ATM is placed.Fig. 4.5 Sequence diagram4.4 Use Case DiagramUML (use case diagrams) diagrams are fiber of behavioral diagrams designed and defined by Use case analysis. It provides graphical representation of functionality of system in terms actors, they are use cases and use case dependencies. The goal of use case diagram is to show role of each actor and these roles are depicted. Actors and authentication server are two actors. The interaction of user with system is done with use cases by forming topology, transmission range is selected and source and sink also selected. Actors are a person, organization or it can be an external agent/system that plays a role in system interactions.Sequence of actions providing information about actor is described with use case and diagrammat ically shown with horizontal ellipse. Following figures shows use case diagrams for ATM deployment.Fig. 4.7 Use case diagram for InitializationFig. 4.8 Use case diagram for fitness calculationFig 4.9 Use case diagram for ATM locatorM.Tech/Dept of CSE, SJBIT 1
