Introduction

Warehouse Management System website is useful for the suppliers and the retailers to view their orders and details of the stocks easily without much paper work. It provides the facility to order new stocks and update the details of the new arrivals of the products for the customers.

1.1 Preamble

This project is very helpful for suppliers as they can give the orders to the retailers easily and the details will be stored. The retailers can assign the rates of the products directly through the website and need not go to the store every now and then.

1.2 Motivation

The warehouse Management system is very useful as the details of all the products and the orders will be updated and will not have paper works. When new products arrive it will be updated in the database. All the details about the products can be obtained without any difficulty.

1.3 Goal and Objectives of the Project Report

• To develop general purpose tool to maintain stock and order details and customers can easily view the products via online.

• This project intends to introduce more user friendliness in the various activities such as stock updating, maintenance, and searching.

• Accepting user details and updating details about the users and the stocks.

• Easy to order the stocks/products.

• Authentication of administrative users is done using proper user name and password. So that other users cannot retrieve administrative data.

1.4 Problem Statement

• In an existing System, all process are Handled manually. The admin should refer all the records kept for years ago to simply know the details. This is time consuming.

• This process is very difficult when the number of users increases. There are many limitations for the existing systems. In manual system all the work is done by human intervention due to which there are maximum chances of errors.

• Suppliers had to visit again and again to know about the order details and when the products will be completed and delivered.

• The files were not stored in hierarchical format. Hence searching was big problem. Due to this the updating was difficult. This leads to duplication of records.

1.5 Scope of the Dissertation Report

As the growing demands and heterogeneity of applications are continuously challenging the architectural aspects of the Internet, it becomes necessary to devise an architecture which is flexible in terms of any modification or update of applications or protocols.

• No data duplication

• No Paper Work Required

• Time Efficient

• Cost Efficient

• Automatic data validation

• User friendly environment

• Data security and reliability

• Fast data insertion & retrieval

• Easy performance check

• Format report generation

1.6 Outline of Dissertation Report

The Project Report is encompassed with six chapters in total and it is organized as follows:

Chapter – 1: Introduction:

It gives the details about the research work and the scope and objective of the project report. It also gives the information about the overview of the project report starting with the project explanation such as the introduction. It also briefs the feelings of the authors.

Chapter – 2: Literature Survey:

Determine the relevant background information such as the Internet design goals & principles, initiative towards the OSI reference model, architectural principles, a critical review of Internet dealing with its limitations and issues, future research approaches, and finally the need of net- work architecture.

Chapter-3: Requirement Analysis:

The main goal of the requirements phase is to produce the software requirements specification(SRS), which accurately captures the client’s requirement and forms the basis of the software development and validation. The main basic activity in the requirements phase is requirement analysis.

Chapter -4: System Design:

Deciding which module are needed for the system, the specification of these module should be interconnected is called “SYSTEM DESIGN”. System design is also called Top Level design. The design of a system is a plan for solution for the system here we consider a system to be set of components with clearly defined behavior that interact with each in a fixed manner to produce some behavior.

Chapter-5:Implementation:

Implementation forms an important phase in the system development life cycle. It is a stage of the project work that transforms the design into a work module.

Chapter-6: Testing:

Testing can be stated as the process of validating and verifying that a software program/application is behaving just as expected during the designing phase. Track the errors to understand their causes and any patterns that may exist.

Chapter 2

Literature Survey

Literature survey is a text of a scholarly paper, which includes the current knowledge including substantive findings, as well as theoretical and methodological contributions to a particular topic.

Literature survey use secondary sources and do not report new or original experimental work.

During literature survey, we found the information about the warehouse management system that the products in the system will be very easy to find out if it is categorized. Hence categorization of the products will be easier for the customers to find the required products.

Advantages:

• New information about the proposed system

• Techniques used for user interactions

• How the users wish to have the proposed system and its functionality

Disadvantages:

• Lengthy Modules

• User accessibility

• User security

Literature Survey if very important as the users will be using the system and they will be using the system only if they are happy with the way the system is developed. Hence taking the information from the survey has become mandatory. It will also be helpful if we get to know the ideas how the users wish to have the system developed and the interface they wish to use.

Hardware and software Requirements

3.1 Requirement Analysis

Software Requirement Specification is a technical specification of requirements for the software products. SRS represents an overview of products, features and summarizes the processing environment for development operation and maintenance of the product.

Software Requirement Specification completely describes what the proposed software is supposed to do, without explaining what it actually does. It contains all the basic requirements that are needed for the development of the software.

The main purpose for preparing this document is to give a general insight into the analysis and requirements of the existing system or situation and for determining the operating characteristics of the system. An SRS provides a reference for validation of the final product. The Warehouse Management System is useful for all the suppliers who wish to view the products online and give orders of the stocks quickly and in a easy way. It helps to keep the details of the records and can be viewed even after many years. It will be updated easily without any problem.

3.1.1 Software Requirement Specification

• Windows 7 Ultimate, Windows 8

• Browser Software like Microsoft Internet Explorer 4.0 or later.

• Visual Studio 2010 or later

• .Net as front end.

• SQL Server 2005 and above

3.1.2 Hardware Requirement Specification

• 256 MB of RAM or more.

• 2GB of hard disk space.

• VGA or higher monitor resolution.

• Mouse or other pointing devices.

• Network interface card or Modem.

• LAN Network.

• Processor Intel core i3 and above.

• Communication Devices such as Wi-Fi.

System Design Architecture

Deciding which module are needed for the system, the specification of these module should be interconnected is called “SYSTEM DESIGN”. System design is also called Top Level design. The design of a system is a plan for solution for the system here we consider a system to be set of components with clearly defined behavior that interact with each in a fixed manner to produce some behavior.

4.1 E-R Diagram

An ER model is an abstract way to describe a database. Describing a database usually starts with a relational database, which stores data in tables. Diagrams created to design these entities and relationships are called entity–relationship diagrams or ER diagrams. E-R diagram depicts the various relationships among entities, considering each object as entity.Peter Chen developed ERDs in 1976.

4.2.1 Entity-Relationship Diagram Notation:

Entity: An entity is an object or concept about which you want to store information.

Weak Entity: A weak entity is an entity that must defined by a foreign key relationship with another entity as it cannot be uniquely identified by its own attributes alone.

Key attribute:A key attribute is the unique, distinguishing characteristic of the entity. For example, an employee’s social security number might be the employee’s key attribute.

4.2 Data Flow Diagram

A data flow diagram (DFD) is a graphical representation of the “flow” of data through an information system, modelling its process aspects. Often they are a preliminary step used to create an overview of the system which can later be elaborated. DFDs can also be used for the visualization of data processing (structured design).

A DFD shows what kinds of information will be input to and output from the system, where the data will come from and go to, and where the data will be stored. It does not show information about the timing of processes, or information about whether processes will operate in sequence or in parallel.

4.2.1 Description of the Documents

The notations used in the diagram are:

Process:

A process transforms incoming data flow into outgoing data flow.

Data Store:

Data stores are repositories of data in the system. They are sometimes

also referred to as files.

External Entity:

External entities are objects outside the system, with which the system

Communicates. External entities are sources and destinations of the

system’s inputs and outputs.
