Using The Simplified Ood Methodologywrite Down A Detailed Description

Using the simplified OOD methodology: Write down a detailed description of the problem. Identify all the (relevant) nouns and verbs. From the list of nouns, select the objects. Identify the data components of each object. From the list of verbs, select the operations. Write a short paper in response to the following prompt: Your local police department wants to design new software to keep track of people, property, and criminal activity. List at least three classes you think should be in the design. For each class, identify some data members and methods.

Paper For Above instruction

The development of software for law enforcement agencies is a complex task that requires careful analysis of the key entities involved and the operations needed to manage these entities effectively. Using the simplified Object-Oriented Design (OOD) methodology, this paper identifies relevant nouns and verbs from the problem description, selects core objects (classes), and determines their data components and operations. The goal is to design a system that efficiently tracks people, property, and criminal activity within the police department's scope.

Problem Description Analysis

The core problem involves creating software that manages information related to individuals, assets, and unlawful activities. The system should facilitate data storage, retrieval, and management, supporting police officers in their daily tasks. As an initial step, relevant nouns (entities) and verbs (actions) are identified from the problem statement.

Nouns (Entities):

- People (individuals, suspects, witnesses, officers)

- Property (personal belongings, vehicles, valuables)

- Criminal activity (crimes, offenses, incidents)

- Software (the application itself)

- Data components (attributes related to these entities)

Verbs (Operations):

- Track (monitor)

- Record (log)

- Manage (organize)

- Update

- Search

- Assign

- Report

From these lists, the main objects (classes) are derived as those entities that require data encapsulation and associated behaviors.

Selection of Classes

Based on the nouns and verbs, three key classes are identified:

1. Person

2. Property

3. Crime

Class Descriptions with Data Members and Methods

1. Person Class

The Person class represents individuals involved in or related to criminal activities. This includes suspects, victims, witnesses, and police officers.

Data Members:

- PersonID (Unique identifier)

- Name

- Address

- PhoneNumber

- DateOfBirth

- Role (e.g., suspect, victim, officer, witness)

Methods:

- recordInfo()

- updateInfo()

- displayInfo()

- assignRole(roleType)

- searchByName(name)

This class allows the system to store detailed information about individuals and perform functions like updating details or searching for a person based on name or ID.

2. Property Class

The Property class models various assets that might be involved in crimes or need to be tracked during investigations.

Data Members:

- PropertyID (Unique identifier)

- Description

- Type (e.g., vehicle, jewelry, electronics)

- Owner (linked to Person object)

- Location

- Status (e.g., recovered, stolen, returned)

Methods:

- recordProperty()

- updateStatus()

- displayProperty()

- transferOwnership(newOwner)

This class supports recording new property, updating its status, and transferring ownership, thereby assisting in inventory management and recovery processes.

3. Crime Class

The Crime class encapsulates details about criminal incidents.

Data Members:

- CrimeID (Unique identifier)

- CrimeType (e.g., burglary, assault, theft)

- DateTime

- Location

- Suspect (linked to Person object)

- Victim (linked to Person object)

- Property involved (linked to Property object)

- Status (e.g., open, closed, under investigation)

Methods:

- recordCrime()

- assignSuspect()

- updateStatus()

- generateReport()

- searchCrimeByType()

This class helps in logging crimes, associating suspects, victims, and properties, and tracking the status of investigations.

Integration and Operations

The classes interact to provide comprehensive tracking and management. For example, when a new crime is recorded, associated Person and Property objects are linked to the Crime object. Operations such as searching for all crimes involving a specific suspect or property are facilitated through class methods.

Conclusion

By applying the simplified OOD methodology, the police department’s software system can be efficiently designed around core classes that encapsulate relevant data and functions. The Person, Property, and Crime classes form the backbone of the system, enabling detailed data management and operational effectiveness essential for law enforcement activities.
