1. It is recommended that TravelFun use the Object-Oriented (O-O) technique for the construction of its information system. O-O methodology has significant advantages over conventional analysis and modeling tools, making it especially well-suited for developing, complex projects such as this one. First off, modularity and reusability are encouraged by the O-O technique. It enables the analysts to dissect the system into objects—smaller, more manageable units of the system. These objects make it simpler to comprehend, alter, and expand the system over time by encapsulating data and behavior. For TravelFun, this means having the flexibility to quickly adjust to shifting consumer tastes and vacation travel trends. Second, the O-O methodology places a strong emphasis on real-world modeling, matching the actual entities and interactions in the holiday travel domain with the system's structure. By doing this, the likelihood of miscommunications between developers and stakeholders is decreased and TravelFun's information system is guaranteed to precisely reflect the business operations and needs. Traditional methods, on the other hand, could find it difficult to fully capture the nuances of the leisure travel market. O-O approach also promotes cooperation and teamwork. Independent object development enables parallel work on various system components. TravelFun's expansion goals are in line with this cooperative approach, which allows for a quicker development cycle and an early entry into the cutthroat vacation travel industry. To summarize, TravelFun's information system is most suited for the Object-Oriented technique due to its collaborative nature, real-world alignment, and adaptability. It guarantees the system's efficiency, flexibility, and adaptability—all essential components of a profitable foray into the leisure travel industry. 2. I would not provide the coworker who was not present at the session the training materials in this case. Sharing these resources, while seemingly useful, would devalue the certification and may compromise the integrity of the training program. The effort and commitment of those who did attend the training are compromised when a coworker has access to the training materials without physically attending the session. Acquiring a certification need to demonstrate an individual's comprehension and proficiency in the subject matter, which is attained by actively engaging in the training course. The certification process loses significance for individuals who obtained it through legal ways when materials are shared with someone who did not put in the necessary time and effort to complete the course. Preserving the integrity and standards of the certification is also crucial. If someone is allowed to take the test without the required preparation, people may end up earning credentials without the requisite abilities and knowledge, which might damage the certification's and the organization's image. In order to maintain the norms and tenets of professional growth, it is imperative that information sharing within a team be encouraged. Rather of giving the colleague access to the documents, I may provide assistance and direction in locating relevant resources or recommend more training possibilities. I could maintain the integrity of the certification process while also encouraging a culture of learning within the team in this way.
