Analysis Class Diagram
a) Class Diagram Definition
Class diagram is a part of unified modelling languages which offers a structure and
overview of a system methods, attributes and classes. The diagram also defines the set the
relationship among different classes. Computer aided software engineering is considered
as a domain of software tools which is mainly utilized to implement and design
application in different areas. It is very much similar as CAD which stands for computer
aided design. It is also utilized to show the functions of the system servers and classes.
Every classes has also mainly two aspects as attributes and functions. In order to provide
a conceptual architecture and model of a primarily design, it is highly recommended to
develop class diagram. Basically, a class diagram consist of several classes along with its
attributes and functions of a system.

c) Summary
The above diagram shows the classes of the TMS system. In this diagram three classes are
identified as Clerical assistant, tour leaders along with branch manager and tour. These are
the main three actors responsible for record a tour. The initiation process can be start by both
clerical assistant and branch manager as they both could add tour and other tour details. The
clerical assistant has several attributes as clerical assistant name, clerical assistant ID, clerical
assistant address. Additionally, the class has several functions like add driver code, add tour
description, add tour leader, add tour location, update tour leader, Check customer payment
details, record payment details, record venue invoices, update record details and update tour
location. The clerical assistant class forms one to many relation with the class tour which also
has one to one relation with the tour leads. The branch class has a one to many relation with
the tour class well.
Communication diagram:
a) Definition
Communication diagram shows the interaction between different objects. Commonly it is
considered as an extension of object diagram which shows message with appropriate
direction from one object to another. It has been helping in the developemnt of the system in
appositive manner that [provide high efficiency rate to the output. It also model alternative
scenarios within the operations that associates with different collaboration of different
objects. It also support the identification of objects, and their attributes and operations that
participate in use cases.

c) Summary
The communication diagram shows the massages along with the direction from one object to
another. The clerical assistant is responsible for add tours along with required details. Clerical
assistant is also responsible for assign tour leads. The tour leads can view the tour details also
able to update tour leads and lastly the branch manager can view payment and other tour
details. Branch manager also can act as a clerical assistant if necessary. Communication
diagram shows the interaction between different objects. Computer aided software
engineering is considered as a domain of software tools which is mainly utilized to
implement and design application in different areas. It is very much similar as CAD which
stands for computer aided design. Commonly it is considered as an extension of object
diagram which shows the message with appropriate direction from one object to another.

Sequence Diagram
a) Definition
Sequence diagrams refers to various interaction between classes and modification of
messages over a timeline. These can be also referred to as event diagrams. A sequence
diagram is an optimal process for validating and visualize numerous runtime scenarios. It
assist to forecast how a system will perform and to determine accountabilities a class may
need to have in the process of modelling a new system. It is very useful for validating logic of
complex operations and Model and document how certain system will behave in various
scenarios.

themselves. A sequence diagram is an optimal process to validate and visualize numerous
runtime scenarios. These can assist to forecast how a system will perform and to determine
accountabilities a class may need to have in the process of modelling a new system.

Task 3:
Computer-Aided Software Engineering (CASE) technologies refers to tools which,
offer automated support for production of software. The aim of presenting CASE tools is
decrease of cost and time for development of software and the improvement of the excellence
of systems developed. The CASE tool market is expansionary grow thing day by day as the
requirement of such tools is necessary. Tourism is also considered as one of the world’s
largest economic activity. In many countries it is a leading business and the most substantial
approach to offer work worldwide. CASE tool is used by numerous industry including the
tourism industry. In this industry mainly three analysis tools are used for Computable General
Equilibrium models, Travel Competitiveness Index and Tourism Satellite Accounts by the
tour planners and destination managers. The effectiveness of such tools in e-learning is
optimal and assist the managers to excute suitable tours by gaining and evaluating useful
insights. Such tools can be also used together to offer competitive advantage and understand
the economical contribution of any certain location or environment However, the usefulness
of such tools cannot assist the estimation manager with policy formula. Even though the
practices to use such tolls in tourism has been around and still progressing (Bashroush et al.
2017 ).
Computer aided software engineering is considered as a domain of software tools which is
mainly utilized to implement and design application in different areas. It is very much similar
as CAD which stands for computer aided design. It is widely used for developing
maintainable, high quality and defect frre application as necessary in different domain. It is
also often considered to associate with the development of the automated tools in software
engineering used in the earlier development process (Kruser et al. 2015). It supports in

of functional and process description, development of top-level design, establishing a
relationship between requirements and models, relation of data flow and entity models.
CASE are mainly developed to upgrade and enhance the adoption of computing system
which is very significant for computer based programs that mostly used by business. The
dependency on this tools is also increasing because of the assistant to increase in the growth
and take effective strategy for advancement. The main reasons for developing the CASE tool
is followed:
 The development speed increased while developing the software.
 Efficiently transfer information among the tools.
 Manipulate and create documentation
 Develop design and enhanced analysis
 Optimum utilization of existed information.
 Enrich data flow and graphical techniques.
