Worksheet This table contains the information about the various supply order made in the current year including their LPP reference, Tender Price, Price List of respective equipments.
A data dictionary contains a list of all files in the database, the number of records in each file, and the names and types of each field. Most database management systems keep the data dictionary hidden from users to prevent them from accidentally destroying its contents. Technologies Used www. It also has the scalability, availability, and security features required to operate as the data storage component of the largest Web sites. SQL Server Enterprise Edition supports features such as federated servers, indexed views, and large memory support that allow it to scale to the performance levels required by the largest Web sites.
The SQL Server relational database engine supports the features required to support demanding data processing environments. The database engine protects data integrity while minimizing the overhead of managing thousands of users concurrently modifying the database. SQL Server distributed queries allow you to reference data from multiple sources as if it were a part of a SQL Server database, while at the same time, the distributed transaction support protects the integrity of any updates of the distributed data.
Replication allows you to also maintain multiple copies of data, while ensuring that the separate copies remain synchronized. You can replicate a set of data to multiple, mobile, disconnected users, have them work autonomously, and then merge their modifications back to the publisher. SQL Server also supports a standards-based programming model integrated with the Windows DNA, making the use of SQL Server databases and data warehouses a seamless part of building powerful and scalable systems.
These features allow you to rapidly deliver SQL Server applications that customers can implement with a minimum of installation and administrative overhead.
SQL Server includes tools for extracting and analyzing summary data for online analytical processing. SQL Server also includes tools for visually designing databases and analyzing data using English-based questions. Server applications provide a component called an MMC snap-in that presents MMC users with a user interface for managing the server application.
In addition to these utilities, SQL Server contains several wizards to walk administrators and programmers through the steps needed to perform more complex administrative tasks.
Net Introduction on. NET Framework. NET is the framework for which we develop applications. It sits in between our application programs and operating system. Applications developed for. NET run inside. NET and are controlled by. It supports both Windows and web applications. NET provides an object oriented environment. It ensures safe execution of the code by performing required runtime validations. For example, it is never possible to access an element of an array outside the boundary.
Similarly, it is not possible to a program to write into another programs area, etc. The runtime validations performed by. NET makes the entire environment robust. Components of. NET framework has two main components.
They are: 1. Common Language Runtime 2. NET are run. It provides various services, like memory management and thread management. For example, when a program needs a block of memory, CLR provides the block and releases the block when program is done with the block. All programs targeted to. MSIL is the output of language compilers in.
As every program is ultimately converted to MSIL in. NET, the choice of language is pure personal. A program written in VB. NET and a program written in C are both www. Then MSIL is converted to native code and run. So, whether you write program in C or VB. MSIL in. NET is same as Bytecode in concept. NET Class Library. NET comes with thousands of classes to perform all important and not-so-important operations. Its library is completely object oriented, providing around classes to perform just about everything.
Visual Basic. NET VB. NET framework. The great majority of VB. NET developers use Visual Studio. NET provides the easiest, most productive language and tool for rapidly building Windows and Web applications. NET comes with enhanced visual designers, increased application performance, and a powerful integrated development environment IDE. It also supports creation of applications for wireless, Internet-enabled hand-held devices.
The following are the features of Visual Basic. NET with. NET Framework 1. Some Features of Vb. NET comes with features such as a powerful new forms designer, an in- place menu editor, and automatic control anchoring and docking. NET delivers new productivity features for building more robust applications easily and quickly.
With an improved integrated development environment IDE and a significantly reduced startup time, Visual Basic. NET offers fast, automatic formatting of code as you type, improved IntelliSense, an enhanced object browser and XML designer, and much more.
You can double-click and write code to respond to events. NET we can build applications more rapidly and deploy and maintain them with efficiency.
The flexibility of ADO. NET enables data binding to any database, as well as classes, collections, and arrays, and provides true XML representation of data. Seamless access to ADO enables simple data access for connected data binding scenarios. Using ADO. NET, Visual Basic.
Improved Coding You can code faster and more effectively. A multitude of enhancements to the code editor, including enhanced IntelliSense, smart listing of code for greater readability and a background compiler for real-time notification of syntax errors transforms into a rapid application development RAD coding machine. Direct Access to the Platform Visual Basic developers can have full access to the capabilities available in.
Developers can easily program system services including the event log, performance counters and file system. Full Object-Oriented Constructs You can create reusable, enterprise-class code using full object-oriented constructs. Language features include full implementation inheritance, encapsulation, and polymorphism. Structured exception handling provides a global error handler and eliminates spaghetti code.
Testing and Debugging Software testing is a critical element of the ultimate review of specification design and coding. Testing of software leads to the uncovering of errors in the software functional and performance requirements are met. Testing also provides a good indication of software reliability and software quality as a whole. The result of different phases of testing are evaluated and then compared with the expected results. If the errors are uncovered they are debugged and corrected. A good test case is one that has a probability of finding an as yet undiscovered error.
A successful test is one that uncovers an as yet undiscovered error. Our Objective is to design test processes that systematically uncover different classes of errors and do so with minimum amount of time and effort. All the features to be tested are noted as follows. Testing plan can begin as soon as the requirement model is complete.
Detailed definition of the test cases can begin as soon as the design is solidified. Therefore, the entire test can be planned before any code has been generated.
The first test planned and executed generally focus on the individual modules. As testing progresses testing shifts focus in an attempt to find errors in integrating clusters of modules and ultimately in the entire system 5. Test Case Before the project is released, it has to has pass through a test cases suit, so that the required functionality is met and previous functionality of the system is also not broken to do this, there is an existing test cases which checks for the previous functionality.
New test cases are prepared and added to this existing test suit to check for the added functionality. Test case describes an input description and compare the observed output with expected output to know the outcome of the test case. If it is different, then, there is a failure and it must be identified.
Test Cases for different field used. The unit testing is normally considered as an adjunct step to coding step. A stub serves to replace the modules that are subordinate to the modules to be tested. A stub may do minimal data manipulation, prints verification of entry and returns. Approaches used for Unit Testing were: Functional Test: Each part of the code was tested individually and the panels were tested individually on all platforms to see if they are working properly. In between there involves the logic layer for effectively and correctly manipulating the request.
The 3-tier includes the following: 2. It provides core function of the system as well as connectivity to the data tier, which simplify tasks that were done by the clients tier. This is the actual DBMS access layer or object layer also called the business object. The database backend stores information which can be retrieved by using the mysql database Connectivity.
In one view, database can be classified according to types of content: bibliography, full-text, numeric, and image. In computing, database are sometime classified according to their organizational approach. A distributed database is one that can be dispersed or replicated among different points in a network. A relational database is a digital database whose organization is based on the relational model of data. This model organizes data into one or more tables of rows and columns.
These tables here have the relation. The relation is maintained by the unique key defined in each row. The key can be primary and foreign depending on their nature of connection. The standard user and application program interface to a relational database is the structured query language SQL. SQL statement are used both for interactive queries for information from relational database and for gathering data for reports.
It can either be a normal attribute that is guaranteed to be unique or it can be generated by the DBMS. Foreign Key A foreign key is a column or group of column in a relational database table that provides a link between data in two tables.
In foreign key reference, a link is created between two tables when the column or columns that hold the primary key value for one table are referenced by the column or column in another table thereby establishing a link between them. In fact, SQL is the only language the most database actually understand.
Whenever you interact with such a database, the software translates your commands into SQL statement that the database knows how to interpret. Consistency — every transaction must leave the database in a consistent correct state, i.
An aborted transaction does not change the database state it has started from, as if it never existed atomicity above. Isolation — Transactions cannot interfere with each other as an end result of their executions. Moreover, usually depending on concurrency control method the effects of an incomplete transaction are not even visible to another transaction. Providing isolation is the main goal of concurrency control. Initially we bounded our research to find the general reasons that emerged the needs of Inventory Management System.
We used different techniques to collect the data that can clearly give us the overall image of the application. The techniques we used were interview with the developers, visiting online websites that are presented as the templates and visiting some organization to see their IMS application. We have even visited some organization in Kathmandu valley and analyze its importance and try to develop the project by fulfilling all the weakness that were found in the application.
We then decided to bulid same type of application with different logic flow and new language which will be suitable for the small organization.
Once it is automated all the functions can be effectively managed and the organization can achieve the competitive advantage. The system is medium scale desktop application and has affordable price. The benefits include increased efficiency, effectiveness, and the better performance. Comparing the cost and benefits the system is found to be economically feasible.
The solution provided by this system will be acceptable to ultimate solution for the stock management. The reasonable timeline reveals that the system development can be finished on desired time framework.
A Gantt chart is a graphical representation of a project that shows each activity task as a horizontal bar whose length is proportional to its time for completion.
A Gantt chart for the project deliverables within time frame. It is a diagrammatic representation of the algorithm. The Process flow Diagram of our application is shown below: Figure 4. The main purpose of a use case diagram is to show what system functions are performed for which actors.
Actor An actor is a person, organization or external system that plays a role in one or more interactions with the system System boundary boxes optional A rectangle is drawn around the use case called the system boundary box to indicate scope of the system.
It is used to develop console and graphical user interface applications along with Windows Form applications, websites, web applications, and web services in both native code together with managed code for all platforms supported by Microsoft Window, Windows Mobile, Windows CE,.
NET Framework,. Microsoft Visual Studio simplifies the basic tasks of creating, debugging and deploying applications. Microsoft Visual Studio comes with. NET Framework and supports applications targeting Windows.
It has integrated support for developing Microsoft Silverlight applications, including an interactive designer. Microsoft Visual Studio offers several tools to make parallel programming simpler: in addition to the Parallel Extensions for the. The Visual Studio code editor now highlights references; whenever a symbol is selected; all other usages of the symbol are highlighted.
NET projects. Quick Search supports substring matches and camel Case searches. The Call Hierarchy feature allows the developers to see all the methods that are called from a current method as well as the methods that call the current one.
IntelliSense in Visual Studio supports a consume-first mode which developers can opt into. In this mode, IntelliSense will not auto-complete identifiers; this allows the developer to use undefined identifiers like variable or method names and define those later.
Visual Studio can also help in this by automatically defining them, if it can infer their types from usage. We have used Visual Studio Community , v It consists of the common language runtime CLR and the.
NET Framework class library, which includes classes, interfaces, and value types that support an extensive range of technologies. NET Framework provides a managed execution environment, simplified development and deployment, and integration with a variety of programming languages, including Visual Basic and Visual C. Net architecture is basically segregated in to three layers namely top, middle and bottom layer.
The bottom layer is CLR, it is the heart of. NET Framework which provides the runtime environment in which programs are executed. The middle layer comprises the next generation of standard system services are brought under the control of the framework, making them universally available and standardizing their usage across languages. NET Framework sits on top of the operating system. There has also been a lot of talk about. NET being ported over by some third-party companies so that a majority of the.
NET Framework could run on other platforms as well. At the base of the. The CLR is the engine that manages the execution of the code. The next layer up is the. This layer contains classes, value types, and interfaces that you will use often in your development process. Most notably within the. NET, which provides access to and management of data. The third layer of the framework is ASP.
NET and Windows Forms. Using ASP. NET, or Jscript. NET compilers provided by Microsoft. Any item or resource that is used in an organization is considered to be in inventory. Arnold, Inventory is generally composed of three elements: raw materials, work-in-progress WIP , and finished goods.
By doing so, operations can be cost controlled successfully. The foundation of any business is knowing what you have, where you have it, and how to manage the supply chain properly. Inventory management is what it sounds like. Knowing what type of inventory you have will help you improve inventory control and inventory management. We will discuss the three most common inventory management strategies used by manufacturers: the pull strategy, the push strategy, and the just in time JIT strategy in this article.
It is important to have a good understanding of what products are in stock, where they are, and how much each item can be purchased. Inventory control will reduce inventory investment and minimize handling costs without negatively impacting customer satisfaction.
