Introduction Australia Wide Systems Integration Group (AWSIG) has been engaged by Broadway Book Shop (BBS) to perform the analysis of their current system and develop models to improve their organizational systems. In this report AWSIG is submitting critical Use-cases, Process and Data models, CRUD diagram and prototype of BBS Web-Store of BBS organizational systems. These designs will facilitate to understand and improve the structure of processes being followed and characteristics of data flowing between the current systems. Data-flow Diagrams are developed during business process modelling which models work flow between different processes in the organizational system. Entity-Relationship diagrams are developed in conceptual data modelling which shows the characteristics and organization of data between the data objects. These designs aid logical understanding of current system and develop improvements to design and build a better information system. Online presence is critical for survival of business. AWSIG has developed a draft model for BBS website which will improve the accessibility for customers and will expand horizon for BBS business.

Critical Use Cases A number of use cases were found to have occurred in the requirements gathering

of the Broadway Bookstore. Firstly the actors were identified, these are the external

entities, which interact with the system. Secondly, the use cases were found, these

are how the system will be used and initiated by the actors.

Actors

• Customers

• Suppliers

• Staff and

• Management

Critical Use Cases

• Record Customer Information

• Record Book list – By Genre, Price

• Record Suppliers

• Record Payment Information

• Create Customer Receipts

• Create Accounting Records

• Create Invoices.

Context Level diagram

A context level diagram was developed to gain an understanding of the scope of the

project and all of the interactions between the system, the external entities interacting

with the system and all of the major flows of information between the system and the

entities. Figure 1 shows the Context Level Diagram for the Broadway Bookshop System.

Data Elements

The data elements required to implement the Broadway Bookshop system are as follows:

• Customer name

• Customer address including city & postcode.

• Customer phone details

• Customer email address

• Customer reference number

• Book genres

• Book titles

• Product (book) reference

• Quantity ordered

• Unit price

• Description

• Order number

• Order date

• Delivery/collection date

• Publishers details

• Employees details

Prototype of Web store Design Prototype of Broadway Book store is designed using HTML web development (www.w3schools.com 1999-2015). Application tool used in designing is Mozilla SeaMonkey (www.seamonkey-project.org) which aids in web development as you can write and test the HTML code at the same interface.

Conclusion & Summary The analysis and activities performed during this assignment has developed

understanding into tools and methodologies to develop improved system designs.

Broadway Bookshop website and system modeling project has identified a number of

elements to be taken into consideration for the implementation of this system, use

cases were identified, outlining the functional elements of the system, including the

Actors and the use cases themselves. Secondly a Context diagram was prepared which

shows the how entities will interact with the system, through data flows into and out

of the system.

A level 0 Data Flow diagram is presented, which shows the flow of data between

entities and processes within the system. An Entity Relationship Diagram was also

included, showing the entities and the relationships they have to the system.

A CRUD diagram was prepared; this shows the interaction of data and its processes.

Finally, a PowerPoint presentation was prepared to show each element of this

project.
