Designing An Essay On Fitness Freak Online Store System.

Describe the Fitness Freak Online Store Software Requirement Specification.

Features of the Fitness Freak Online Store System

In the current world body health and fitness has been considered as one of the vital thing that human being should embrace to ensure they maintain their body health, therefore this report is about the designing of a fitness freak online store system that will have various functionalities that will enable the customers and the management team to use it.

In this fitness freak system there will be two major parts which includes the customers purchasing modules and the management’s module where each will be having different accessing privileges using their secret usernames and passwords.

However among the system users are the various customers of the fitness products and the member of staffs of the company.

Among the products that will be found in the online store will be in-ears sport headphones, home gym kits, multipurpose jogging armbands, fruits infusion bottles,100% cotton yoga mats, a set of exercise rope, mini-bikes peddlers, exercise balls, the running shoe, relatively fitness trackers and sleep monitors and also the gym bags. 

The fitness freak online shop is a system that will be used by the various people who includes the customers and the staffs as illustrated through the below dataflow diagrams.

The dataflow diagrams below illustrates how the information flows and the interaction of the various system users with the various system components as in the below context diagram.

The below  are the figure indicating the structure of the context diagram of the fitness freak online store system  that show the relationships between the online shop system and the various external entities .

Therefore in this system the customers will be able to shop and order products while the staffs will be able to do updating of the products through this online e-commerce website; however the customers will be able to make the payments for their products using external payment methods which include PayPal, visa card, master card or skill.

The figure 2 below of fitness freak online system consists of total of eight processes which are used in the ordering, updating the store details and making the payments .However the level 0 that makes the entire data flow diagram therefore has the information about the store products, placed orders, customer registration and logins details, details of the invoices and the workers login details.

However the data flow diagram has some data stores which include the, customers, workers, orders invoices, placed orders and the inventories.

While using the system the customers register their details to create account and then uses the login usernames and passwords to login into the system, after the customer login they add the selected items to the cart and then the system check if the products are available and then allow the customer to place the order, after placing of the orders the customer requests for invoice to make the payments.

Upon receiving the invoice the customer enter the payments details and then submit them where the system verifies them if they are accurate, if accurate the payments invoice amount is deducted to complete the payment of the products.

The management workers also uses the system to update the store products details after receiving new stock of products to sell and they also keep on checking the stock status as well.

In this online system there is the flow of information, below is a table showing the data flows and it gives the respective specifications of the Fitness freak online system.

The data flows names	Specifications
Customer registration	The customer details
Customer login	The customer username and password
Add products to shopping cart	Customer adding selected items to the shopping cart
Checking the products inventories	Checking the remaining products stock
Placing order	Placing the order of items on shopping cart
Creating invoices	Create invoices for the customers to know the amount to pay
Making payments	Paying for the products that the customer had bought
Workers logins	Worker username and password
Updating store products	Adding the products to the stock

The system has various interfaces that will allow the user inputs during the system interactions process below are the user interfaces.

The Fitness freak online shop system will be accessed using laptops and desktop computers which will be using Mozilla Firefox and Google chrome browsers, where the access time and speed will be moderately high.

While accessing the system the users require having enough data bundles more than 10mbs to enable efficient loading of the system features including the images of the store products.

However there will be two main users of the system who will be the customers and the workers of the organization.

The system targets many users which will include various groups of people who will be children, youths, and elderly people and therefore the graphics will be attractive to them and the descriptive text will be large enough to be visible by any of the targeted audience also there will be beautiful products for the ladies and nice colors to attract children (Bonczek, 2015).

The system will be highly reliable where the customer’s time will be highly saved since they require shopping for their products from anywhere which is more convenient.

However the customers will be able to have access to variety of the products which he can compare and he will be able to pay using the PayPal method.  

The system will provide the customers with the unique login details which they will be using to log in the system and buy or place order; also the workers also will be having the login details that they will be able to use while updating store products.

However there will be safety in the payment process where the customers will be allowed to pay through the PayPal method which is more secure payment method.

The Fitness Freak online system is small in size and thus requires small storage space while using it, therefore any computer device will just require at least 10mb free space which will be used by the system to run and only little data will be required for the initial system loading.

Below are some of the terms used and their meaning:

1. Data flow diagrams: This diagram consists of context and entity relation diagram that show the flow of the information in the system and how the system interacts with the various external entities (Greenberg,2016).
2. Context diagram: This is the diagram drawn to illustrate the flow of the information in the whole system and shows how the external entities interact with the system.

• Entity relation diagram: This is a diagram used to show how the various entities relate to each other in the storage of data in the system.

In the system design there are various assumptions that I made and they includes the following:

1. The customers can be able to access system using any computer installed with Google chrome and Mozilla Firefox.
2. The customers require to login to place orders.

• The customer require to pay using visa card, master card, skrill or PayPal .

1. The customer can buy unlimited number of items if they are in stock.
2. The products will be updated only by the worker who is the system administrator
3. The system will generate an invoice to the customers after adding the products to cart (Alter, 2016).

• While the workers will be updating the products stocks the system will be autonomous and will not cause any conflicts as the customers use the system at the same time since the data inventory will be backed up prior the updating process begin.
• Every time the order is completed and the payment is made by the customers the inventory will be automatically be updated.

The system design and development will take various phases which will have various stages where each stage will take different amount of time that takes a total of 82 days as shown in the below activities table and Gantt chart diagram.

PHASES	ACTIVITIES	NUMBER OF DAYS
1. PLANNING PHASE	Selecting group members	1 Day
	Defining problem	1 Day
	Producing the project schedules	2 Days
