Collage report on Online trading

  1. 1. 1 INTRODUCTION 1. INTRODUCTION The internet’s arrival and its subsequent popularity in India have made online trading in India, which is about the online purchase and sales of shares, one of the extremely popular means of trading. Both beginner and experienced traders and investors in India are milking this opportunity by trading online in futures and options, stocks and currencies worldwide. Such opportunities are in the form of reduced brokerage and commissions, better broking services etc. Constructive uses of new technologies have always contributed positively towards improving human life standards and the economy of a country .Such as online trading, in equity markets it increased trade volumes and number of investors trading in stock markets. Online trading was started in India in the year 1995, where a new system is formed which allows the investor to trade through an internet site where the major financial products and services like equities, mutual funds, life insurance, general insurance, loans, share trading, commodities trading, portfolio management and financial planning etc. are directly available for the customer. There is also stock option trading in India. An option is a financial agreement, with a predetermined maturity period and price, for the purchase or sales of the underlying products. Stock options enable the protection of dealers and control of their stocks, in addition to generation of higher earnings. For carrying out online trading in India, you have to open an online demat and trading account, followed with online trading software. For this purpose, you would require a Depository Participant (DP), selection of which should be preceded by extensive research on various determinants. This is time consuming and inefficient. This imposed limits on trading volumes and efficiency. In order to provide efficiency, liquidity, and transparency NSE and BSE introduced nationwide online fully automated “SCREEN BASED TRADING SYSTEM”. Online trading in India is the internet based investment activity that involves no direct involvement of the broker. There are many leading online trading portals in India along with the online trading platforms of the biggest stock houses like the National stock exchange and the Bombay stock exchange. The total portion of online share trading India has been found to have grown from just 3 per cent of the total turnover in 2003-04 to 16 per cent in 2006-07.
  2. 2. 2 The investor has to register with an online trading portal and get into an agreement with the firm to trade in different securities following the terms and conditions listed down on the agreement. The order processing is done in correct timings as the servers of the online trading portal are connected to the stock exchanges and designated banks all around the clock. They can also get updates on the trading and check the current status of their orders either through e-mail or through the interface. Brokerages also provide research content on their websites, such that the clients can take their own decisions on stocks before investing. In spite of many private stock houses at present involved in online trading in India, the NSE (National Stock Exchange) and BSE (Bombay Stock Exchange) are among the largest exchanges. They handle huge daily trading volumes, supporting large amounts of data traffic and processing a countrywide network. The automated online systems used for trading by the national stock exchange and the Bombay stock exchange are the NIBIS or NSE’s Internet based System and NEAT for the national stock exchange and the BSE online trading system or BOLT for the Bombay stock exchange. Thanks to the ever-rising number of people owning computers along with a readily available internet access, online stock trading in India is simplified manifolds. This is because investments can now be easily controlled by traders themselves as a result of extensive availability of all types of information on the web.
  3. 3. 3 HISTORY 2. HISTORY As early as 1969, digital trading systems called electronic communications networks (ECNs) were being used by brokerages to display in-house the bid and ask prices for stocks. By the late 1980s, as the financial industry began to realize the potential of a public internet and ownership of personal computers was growing in popularity, some of the leading brokerages began to look more closely at ECNs. Several industrious brokerages either developed software or bought companies that had developed software to link up stock traders with current stock price information, thereby matching up buyers with sellers easily and efficiently and with significant cost savings. It was 1981 at my local Radio Shack. But just one year later in 1982, the first full service electronic consumer equity trading system for buying and selling stocks, mutual funds and commodities using a PC came online. It was called NAICO-NET and it was offered by a company called North American Holding Corp. located in East Hartford, CT. The system was ANSI based, meaning it was terminal based but IBM PCs could connect to it via a simple application and it connected traders from all over the world. Trades were sent directly to Pershing Corp. (Donaldson Lufkin & Jenrette) for high speed clearing and the trader subscription base quickly rose to over 5,000. And the rest, as they say, is history – the history of online stock trading. Over the next 10 years, the history of online stock trading developed slowly, temporarily crippled by the stock market crash of 1987, a recession and the Gulf War. Additionally, the costs were still generally high for online access for retail stock traders. It was in the 1990s that things shifted and online stock trading really took off. Trade*Plus was another pioneering company in the history of online stock trading and in 1985 offered some of the very first retail trading platforms on America Online and CompuServe. Trade*Plus continued to offer its services to brokerages, but in 1991 one of the founders of Trade*Plus, William Porter, created a new subsidiary company called E*TRADE Securities, Inc. For retail traders, the coming together of better accessibility to information, the ease of an electronic trade and decreased cost to process a trade enhanced the popularity of online stock trading and it began to take off. By the mid-1990s, more than 20 percent of the nation’s population was investing in stock, compared with less than 5 percent the decade before. To illustrate the impact this had on E*Trades’ bottom line, its revenues increased from $850,000 in 1992 to $11 million in 1994 and was rated as the fastest growing company in America that year. The rush to become an online stock trading broker was on!
  4. 4. 4 Another well-known company, TD Ameritrade, originally started out as a company called First Omaha Securities and in 1995 the company acquired K. Aufhauser& Company, Inc. and its WealthWeb, which had begun offering online stock trading in August 1994. The company that was to eventually become TD Ameritrade continued to merge and acquire other companies, quickly becoming one of the largest online brokerages. A conversation about the history of online stock trading must include the fact that Charles Schwab, for a long time, had been cornering a huge portion of the financial industry’s market share through branch offices and discount fees. They continued to build market share at a strong pace all through the 1990s. Charles Schwab was only slightly late to the online stock trading party and became another strong leader as an online stock trading provider in the late 1990s, combining their market share with strong promotional activity. They started by providing a web presence in 1995 and at the time had $181.7 billion in total client assets. The very next year their online stock trading went live and in 1996, they ended the year with $253 billion in total client assets. By the next year, 1997, Charles Schwab registered it’s one millionth online account, reached total client assets of $437 billion and ranked as the top online broker in the U.S.
  5. 5. 5 SYSTEM ANALYSIS 3. SYSTEM ANALYSIS 3.1 DEFINATION System Analysis is the detailed study of the various operations performed by the system and their relationships within and outside the system. Analysis is the process of breaking something into its parts so that the whole may be understood. System analysis is concerned with becoming aware of the problem, identifying the relevant and most decisional variables, analyzing and synthesizing the various factors and determining an optimal or at least a satisfactory solution. During this a problem is identified, alternate system solutions are studied and recommendations are made about committing the resources used to design the system. 3.2 DESCRIPTION OF PRESENT SYSTEM Existing system refers to the system that is being followed till now. Presently all the registrations are done manually. If a person wants to buy computer and accessories, domestic used things, mobile and accessories and many different goods etc., he should directly contact to the various websites such as flip kart, Naaptol, Snap deal etc. which provides the online trading facilities. The main disadvantage is that there will be lot of difficulties for the citizens. So, all these procedures will be a time consuming one. 3.3 LIMITATIONS OF PRESENT SYSTEM  Difficult for persons.  Time consuming.
  6. 6. 6 3.4 PROPOSED SYSTEM Online Trading is aimed at developing a web-based system. In this system the person can sales online and do many things. The details of all the things are made available to them through the website. ADVANTAGES:  This website provides online help for legal queries.  This website helps all the users to view the registration.  The user can post thread in the forum.  The system is user friendly. 3.5 FEASIBILITY STUDY A feasibility analysis usually involves a thorough assessment of the operational (need), financial and technical aspects of a proposal. Feasibility study is the test of the system proposal made to identify whether the user needs may be satisfied using the current software and hardware technologies, whether the system will be cost effective from a business point of view and whether it can be developed with the given budgetary constraints. A feasibility study should be relatively cheap and done at the earliest possible time. Depending on the study, the decision is made whether to go ahead with a more detailed analysis. When a new project is proposed, it normally goes through feasibility assessment. Feasibility study is carried out to determine whether the proposed system is possible to develop with available resources and what should be the cost consideration. Facts considered in the feasibility analysis were.  Technical Feasibility  Economic Feasibility  Behavioral Feasibility
  7. 7. 7 3.5.1 Technical Feasibility Technical Feasibility deals with the hardware as well as software requirements. Technology is not a constraint to type system development. We have to find out whether the necessary technology, the proposed equipment have the capacity to hold the data, which is used in the project, should be checked to carry out this technical feasibility. The technical feasibility issues usually raised during the feasibility stage of investigation includes these  This software is running in windows 7 Operating System, which can be easily installed.  The hardware required is Pentium based server.  The system can be expanded. 3.5.2 Economical Feasibility This feasibility study present tangible and intangible benefits from the prefect by comparing the development and operational cost. The technique of cost benefit analysis is often used as a basis for assessing economic feasibility. This system needs some more initial investment than the existing system, but it can be justifiable that it will improve quality of service. Thus feasibility study should center along the following points:  Improvement resulting over the existing method in terms of accuracy, timeliness.  Cost comparison  Estimate on the life expectancy of the hardware  Overall objective Our project is economically feasible. It does not require much cost to be involved in the overall process. The overall objectives are in easing out the requirement processes. 3.5.3 Behavioral/ Operational Feasibility This analysis involves how it will work when it is installed and the assessment of political and managerial environment in which it is implemented. People are inherently resistant to change and computers have been known to facilitate change. The new proposed system is very much useful to the useful to the users and there for it will accept broad audience from around the world.
  9. 9. 9 Waterfall Model The waterfall model derives its name due to the cascading effect from one phase to the other as is illustrated in above figure. In this model each phase well define starting and ending point, with identifiable deliveries to the next phase. Note that this model is sometime referred to as the linear sequential model or the software life cycle model. The water fall diagram is basically divided into following 5 models.  Requirement  Design  Implementation  Verification  Maintenance  Requirement:- In the requirement phase the need to create the application is specified. What is the need of the system is defined. What information to be feeder to create the application will come under the requirement phase?  Design: After the requirement phase the next phase is the Design phase where the application is designed according to the forms and other modules created. This phase is much important phase because it will structure the layout of your application.  Implementation: Implementation is the process of having a system personnel phase check out and put new equipment into use, train users, install new application and construct any file of data need to use it.  Verification: After the whole application is being the developed the main phase is the verification phase where the whole application tested and verified to check the whole application.  Maintenance: After the successful verification of the application the main phase is the maintenance phase where the application needs to be maintained for its successful operation in future.

It spans clients, servers and developer tools and consists of:  The .NET Framework programming model that enables developers to build Web- based applications which expose their functionality programmatically over a network using standard protocols such as SOAP and HTTP.  Developer tools such as Microsoft Visual Studio .NET, which provide a rapid application integrated development environment for programming with the .NET Framework.  A set of servers including Microsoft Windows 2000, Microsoft SQL, Server and Microsoft BizTalk Server that integrates, runs, operates and manages XML Web services and applications.  Client software such as Windows XP, Windows CE and Microsoft Office XP that helps developers deliver a deep and compelling user experience across a family of devices and existing products. The .NET Framework is the programming model of the .NET environment for building, deploying and running Web- based applications, smart client applications and XML Web services. It manages much of the plumbing, enabling developers to focus on writing the business logic code for their applications. The .NET Framework includes the common language runtime and class libraries.

  13. 13. 13 SPECIFICATION OF LANGUAGE 6. OVERVIEW OF THE LANGUAGE USED 6.1 MICROSOFT VISUAL STUDIO Microsoft Visual Studio is Microsoft’s flagship software development product for computer programmers. It centers on an integrated distribution environment which has programmers create stand alone, and web services that run on any platforms supported by Microsoft’s .Net Framework (for all versions after 6). Supported platforms include Microsoft windows, servers and workstations, Pocket PC, Smart Phones and World Wide Web browsers not the Java Virtual Machine that all other java tools target. VISUAL STUDIO 2005 The most important language added in this version was the introduction of generics, which are similar in many aspects to C++ templates. This potentially increases the number of bugs caught at compile- time instead of run- time by encouraging the use of strict type checking in areas where it was not possible before, C++ also got a similar upgrade with the addition of C++/CLI which is slated to replace the use of Managed C++. Other new features of Visual Studio 2005 include the “Development Designer” which allows application designs to be validated before deployments, an improved environment for web publishing when combined with ASP.NET 2.0 and load testing to see application performance under various sorts of user loads. Visual Studio 2005 also added extensive 64- bit support. While the development environment itself only available as a 32- bit application, visual C++ 2005 supports compiling for (x64AMD64 and EM64T) as well as IA- 64 (Itanium). The platforms SDK include 64- bit and 64-bit versions of the libraries.
  14. 14. 14 6.2 NET FRAMEWORK SDK The .NET framework is an integral windows component that supports building and running the next generation of applications and XML web services. The key component of the .NET frame work are the common language run time and the. NET frame work class library, which includes ADO.NET, ASP.NET and windows forms. The .NET framework provides a wide variety of programming languages. This framework is made up of the following parts:  The common language runtime(CLR)  The base class libraries.  Object oriented internet development with ASP.NET  Rich client user interface using windows forms  RAD for the internet using web forms 6.3 OVERVIEW OF THE .NET FRAME WORK The .NET framework is a new computing platform that simplifies application development in the highly distributed environment of the internet. The .NET framework is designed to fulfill following objectives:  To provide a consistent object oriented programming environment whether object code is stored and executed locally but internet- distributed or executed remotely.  To provide a code execution environment that minimizes software deployment and versioning conflicts.  To provide a code execution environment that guarantees safe execution of code, including code created by an unknown or semi trusted third party.  To provide a code execution environment that eliminates the performance problem of scripted or interpreted environments.
  15. 15. 15  To make the developer experience consistent across widely types of application, such as windows based applications and web based applications.  To build all communication on industry standards to ensure that code based on the .NET framework can integrate with any other code. The .NET framework has two main components: the common language runtime and the .Net framework class library. The common language runtime is the foundation of the .NET framework. You can think of the runtime as an agent that manages code at execution time, and remoting while also enforcing strict type safely and other forms of code accuracy that ensure security and robustness in fact the concept of code management is a fundamental principle of the runtime. Code that targets the runtime is known as managed code, while code that does not target the runtime is known as unmanaged code. The class library, the other main component of the .NET frameworks is a comprehensive, object-oriented collection reusable types that you can use to develop applications ranging from traditional command line or graphical user interface (FGUI) applications to application base d on the latest innovations provided by ASP.NET, such as web forms and XML web services. The .NET framework can be hosted by unmanaged component that load the common language runtime into their processes and initiate the execution of managed code. ASP.NET works directly with the runtime to enable ASP.NET application and XML web services, both of which are discussed later in this topic, Internet explorer is an example of unmanaged application that hosts the runtime (in the form of a MIME type extension). Using internet explorer to the host runtime enables you to embed managed components or windows forms controls in HTML documents. Hosting the runtime in this way makes mobile code 9similar to Microsoft Active Xr controls) possible, but with significant improvement that only managed code can offer, such as semi-trusted execution and secure isolated file storage.
  16. 16. 16 The following illustration shows the relationship of the common language runtime and the class library to your application and to the overall system. The illustration also shows how managed code operated with in a larger architecture. We can use the .NET framework to develop the following types of application and services:  Console applications  Window GUI application (Windows Forms) ASP.NET applications  XML Web services  Windows services 6.4 COMMON LANGUAGE RUNTIME (CLR) The common language runtime (CLR) is responsible for runt-time services such as language integration; security enforcement; and memory, process and thread management. In addition, it has a roll at development time when features such as life cycle management strong type naming, cross-language exception handling, dynamic binding and so on, reduce the amount of code that a developer must write to turn the business logic the reusable component. The runtime can be hosted by high performance, server-side applications, such as Microsoft Internet Information Services (IIS) for building web applications with ASP.NE and the next release of Microsoft SQL Server. This infrastructure enables you to use code “managed “ by the .NET framework to write your business logic, while still enjoying the superior performance of the industry’s best enterprises servers that support runtime hosting. 6.5 ASP.NET ASP.NET is a set of Microsoft.NET framework technologies used for building web applications and XML Web services. ASP.NET page execute on the server and generate markup such as HTML, WML or XML that is sent to a desktop or mobile browser. ASP.NET pages use a compiled, event-driven programming model that improves performance and enables the separation of application logic and user interface. Both ASP.NET pages and ASP.NET web services files contain server-side (as opposed to client side logic) written in Visual basic .NET, C#.NET or any .NET compatible language, Web applications and XML Web Services take advantage of the features of the common language runtime, such as type safety, inheritance, language, interoperability, versioning, and integrated security.
  17. 17. 17 6.6 IIS Microsoft Internet Information S4ervices (IIS; formerly called Server is a set of Internet-based services for servers using Microsoft Windows. It is the world’s second most popular web server in terms of overall websites. As of September 2007 it served 34.94% of all websites and 36.63% of all active websites according to Net craft. The servers currently include FTP, SMTP, NNTOP, and HTTP/HTTPS. 6.7 ADO.NET ADO.NET provides consistent access to data sources such as Microsoft SQL Server and XML, as well as to data sources exposed through OLE DB and ODBC. Data sharing consumer applications can use ADO.NET to connect to these data sources and retrieve, manipulate and update the data that they contain. ADO.NET separates data access from data manipulation into discrete components that can be used separately or in tandem. ADO.NET includes .NET Frame work data providers for connecting to a database, executing commands and retrieving results. Those results are either processed directly, placed in and ADO.NET Dataset objects in order to be exposed to the used in an ad hoc manner, combined with data from multiple sources or remoted between tiers. The ADO.NET Dataset object can also be used independently of a .NET Framework data provider to manage data local to the application or sourced from XML. The ADO.NET classes are found in System.Data.dll and are integrated with the XML classes found in System.Xml.dll. When compiling code that uses the System. Data, namespace reference both System.Data.dll and System.Xml.dll. ADO.NET provided functionality to developers writing managed code similar to the functionality provided to native component object model (COM) developers by ActiveX Data Objects (ADO).
  18. 18. 18 6.8 ADO.NET COMPONENTS There are two components of ADO.NET that you can use to access and manipulate data:  .NET Framework data providers.  The Dataset .NET FRAMEWORK DATA PROVIDERS The .NET Framework Data providers are components that have been explicitly designed for data manipulation and fast, forward-only, read-only access to data. The connection object provides connectivity to a data source. The command object enables access to database commands to return data, modify data, run stored procedures and send or retrieve parameter information. The Data Adapter provides a high-performance stream of data from the data source. Finally, the Data Adapter provides the bridge between the Data Set object and the data source. The Data Adapter uses command object to execute SQL commands at the data source to both load the Data Set with data and reconcile changes made to the data in the Data Set back to the data source. THE DATASET The ADO.NET Data Set is explicitly designed for data access independent of any data source. As a result, it can be used with multiple and differing data sources used with XML data or used to manage data local to the application. The Data Set contains a collection n of one or more Data Table objects made up to rows and columns of data as well as primary key, foreign key, constraint and relation information about the data in the Data Table objects.
  19. 19. 19 6.9 BENEFITS OF ADO.NET ADO.NET offers several advantages over previous versions of ADO and over other data access components. These benefits fall into the following categories: 1. Interoperability 2. Maintainability 3. Programmability 4. Salability 6.10 MICROSOFT DATA ACCSS COMPONENTS (MDAC) Microsoft Data Access Components (MDAC) is a collection of core files provided to help applications by providing a means of accessing data. MDAC includes core files for Open Database Connectivity (ODBC), ActiveX Data Objects (ADO), OLEDB, Network libraries and client configuration tool for SQL Server. Depending on your data access strategy, you may need to ensure that MDAC is installed on the client computers, the business servers, the Web servers or the database servers. MDAC 2.6 or later is required by the .NET Framework and at least MDAC 2.7 SP1 is recommended.
  20. 20. 20 SYSTEM DESIGN 7. SYSTEM DESIGN DEFINATION The most creative and challenging face of the system development is System Design. It provides the understanding and procedural details necessary for implementing the system recommended in the feasibility study. Design goes through the logical and physical stages of development. In designing a new system, the system analyst must have a clear understanding of the objectives, which the design is aiming to fulfill. The first step is to determine how the output is to be produced and in what format. Second, input data and master files have to be designed to meet the requirements of the proposed output. The operational phases are handled through program construction and testing. Design of a system can be defined as a process of applying various techniques and principles for the purpose of defining a device, a process or a system in sufficient detail to permit its physical realization. Thus system design is a solution to “how to” approach to the creation of a new system. Thus important phase provides the understanding and the procedural details necessary for implementing the system recommended in the feasibility study. The design step provides a data design, architectural design, and a procedural design. 7.1 OUTPUT DESIGN In the output design, the emphasis is on producing a hard copy of the information requested or displaying the output on the CRT screen in a predetermined format. Two of the most output media today are printers and the screen. Most users now access their reports from a hard copy or screen display. Computer’s output is the most important and direct source of information to the user, efficient, logical, output design should improve the systems relations with the user and help in decision-making. As the outputs are the most important source of information to the user, better design should improve the system’s relation and also should help in decision-making. The output device’s capability, print capability, print capability, response time requirements etc. should also be considered form design elaborates the way output is presented and layout available for capturing information. It’s very helpful to produce the clear, accurate and speedy information for end users.
  21. 21. 21 7.2 INPUT DESIGN In the input design, user-oriented inputs are converted into a computer based system format. It also includes determining the record media, method of input, speed of capture and entry on to the screen. Online data entry accepts commands and data through a keyboard. The major approach to input design is the menu and the prompt design. In each alternative, the user’s options are predefined. The data flow diagram indicates logical data flow, data stores, source and destination. Input data are collected and organized into a group of similar data. Once identified input media are selected for processing. In this software, importance is given to develop Graphical User Interface (GUI), which is an important factor in developing efficient and user-friendly software. For inputting user data, attractive forms are designed. User can also select desired options from the menu, which provides all possible facilities. Also the important input format is designed in such a way that accidental errors are avoided. The user has to input only just the minimum data required, which also helps in avoiding the errors that the users may make. Accurate designing of the input format is very important in developing efficient software. The goal or input design is to make entry as easy, logical and free from errors. 7.3 LOGICAL DESIGN Logical data design is about the logically implied data. Each and every data in the form can be designed in such a manner to understand the meaning. Logical data designing should give a clear understanding and idea about the related data used to construct a form.
  22. 22. 22 7.4 DATA FLOW DIAGRAM A Data Flow Diagram (DFD) is a diagram that describes the flow of data and the processes that change data throughout a system. It’s a structured analysis and design tool that can be used for flowcharting in place of or in association with information. Oriented and process oriented system flowcharts. When analysts prepare the Data Flow Diagram, they specify the user needs at a level of detail that virtually determines the information flow into and out of the system and the required data resources. This network is constructed by using a set of symbols that do not imply physical implementations. The Data Flow Diagram reviews the current physical system, prepares input and output specification, specifies the implementation plan etc. Four basic symbols are used to construct data flow diagrams. They are symbols thatrepresent data s ource, data flows, and data transformations and data storage. The points at whichdata are transformed are r epresented by enclosed figures, usually circles, which are called nodes. DATA FLOW DIAGRAM SYMBOLS:- Source or Destination of data - Data Flow - Process - Storage

  26. 26. 26 7.7 Process Model Spiral Model DEFINITION The spiral model, also known as the spiral lifecycle model, is a systems development method (SDM) used in information technology (IT). This model of development combines the features of the prototyping model and the waterfall model. The spiral model is intended for large, expensive, and complicated projects.
  27. 27. 27 The steps in the spiral model can be generalized as follows: 1. A preliminary design is created for the new system. 2. A first prototype of the new system is constructed from the preliminary design. This is usually a scaled-down system, and represents an approximation of the characteristics of the final product. 3. A second prototype is evolved by a fourfold procedure: (I) evaluating the first prototype in terms of its strengths, weaknesses and risks; (ii) Defining the requirements of the second prototype; (iii) Planning and designing the second prototype; (iv) Constructing and testing the second prototype. 4. At the customer's option, the entire project can be aborted if the risk is deemed too great. Risk factors might involve development cost overruns, operating-cost miscalculation, or any other factor that could, in the customer's judgment, result in a less-than-satisfactory final product. 5. The existing prototype is evaluated in the same manner as was the previous prototype, and, if necessary, another prototype is developed from it according to the fourfold procedure outlined above. 6. The preceding steps are iterated until the customer is satisfied that the refined prototype represents the final product desired. 7. The final system is constructed, based on the refined prototype. 8. The final system is thoroughly evaluated and tested. Routine maintenance is carried out on a continuing basis to prevent large-scale failures and to minimize downtime. Advantages  Estimates (i.e. budget, schedule, etc.) get more realistic as work progresses, because important issues are discovered earlier.  It is more able to cope with the (nearly inevitable) changes that software development generally entails.  Software engineers (who can get restless with protracted design processes) can get their hands in and start working on a project earlier.

  30. 30. 30 TESTING 9. TESTING Testing is a process to show the correctness of the program. Testing is needed to show completeness, it improve the quality of the software and to provide the maintenance aid. Some testing standards are therefore necessary reduce the testing costs and operation time. Testing software extends throughout the coding phase and it represents the ultimate review of configurations, design and coding. Based on the way the software reacts to these testing, we can decide whether the configuration that has been built is study or not. All components of an application are tested, as the failure to do so many results in a series of bugs after the software is put to use. 9.1 Black box Testing Black box testing, also called behavioral testing, focuses on the functional requirements of software. This testing approach enables the software engineer to derive the input conditions that will fully exercise all requirements for a program. Black box testing attempts to find the errors like  Incorrect or missing functions  Interface errors  Errors in data structures or external database access  Behavior or performance errors  Initialization and termination errors In Black box testing software is exercised over a full range of inputs and outputs are observed for correctness. 9.2 White box Testing White box testing is also called Glass box testing is a test case design control; structure of the procedural design to derive test cases using White box testing method, the software engineer can derive the test cases that guarantee that all independent paths within the module have been exercised at least once. Exercise all logic decisions on their true or false sides. Execute all loops at their boundaries and within their operational bounds. Exercise internal data structure to ensure their validity.
  31. 31. 31 9.3 Software Testing Strategies Testing involves  Unit testing  Integration testing  Acceptance testing The first level of test is unit testing. The purpose of unit testing is to ensure that each program is fully tested. The second step is integration testing. In this individual program units or programs are integrated and tested as a complete system to ensure that the software requirements are met. Acceptance Testing involves planning and the execution of various types of tests in order to demonstrate that the implemented software system satisfies the requirements. Finally our project meets the requirements after going through all the levels of testing.
  32. 32. 32 SECURITY 10. SECURITY The system security problem can be divided into four related issues: security, integrity, privacy and confidentiality. They determine the file structure, data structure and access procedures. System security refers to the technical innovations and procedures applied to the hardware and operating systems to protect against deliberate or accidental damage from a defined threat. In contrast, data security is the protection of data from loss, disclosure, modifications and destruction. System integrity refers to the proper functioning of programs, appropriate physical security and safety against external threats such as eavesdropping and wiretapping. In comparison, data integrity makes sure that do not differ from original from others and how the organization can be protected against unwelcome, unfair or excessive dissemination of information about it. The term confidentiality is a special status given to sensitive information in a data base to minimize the possible invasion of privacy. It is an attribute of information that characterizes its need for protection. System security is the technical means of providing such protection. In contrast privacy is largely a procedural matter of how information is used.

  39. 39. 39 CONCLUSION 12. CONCLUSION Now a day’s manual process for the citizens to sales for their product such like mobile, computer, laptop, stock share etc… has become a huge task. The main object of the website is to reduce the effort by the candidate and save his time and avoid unwanted rushes at the ZECCO and assure a smooth working schedule at ZECCO for Trading. The main features of this site includes flexibility, reduce manual work in an efficient manner, a quick, convenient, reliable and effective way to apply for their online trading market committee records. The project could very well be enhanced further as per the requirements. Online trading is the new concept in the stock market. In India, online trading is still at its infancy stage. Online trading has made it easy to trade in the stock market as now people can trade while sitting at their home. Now stock market is easily accessible by the people. There are some problems while doing the trade through the internet. Major problem faced by online trader is that the investors are loyal to their traditional brokers, they rely upon the suggestions given by their brokers. Another major problem is that the people don't have full knowledge regarding online trading. They find it difficult to trade themselves, as a wrong entry made by them, can bring them huge losses.
