Answer:
2. A data modelling project using a packaged data model REQUIRES A GREATER SKILL than a project not using a packaged data model.
Explanation:
1a. Review of universal models:
A data model is an abstract model that organizes elements of data and standardizes how they relate to one another and to the properties of real world entities. It has become the standard approach used towards designing databases.
A universal data model is a template data model that can be reused as a starting point or a building block to jump-start development of a data modelling project, industry specific model, logical data models.
1b. Discuss how these are being used more widely today.
*Universal data models helps professional reduce development time, improve consistency and standardization while achieving high quality models.
*Higher quality: just as architects consider blue prints before constructing a building, one should also consider data before building an app. A data model helps define the problem, enabling one to consider different approaches and choose best ones.
*By properly modelling and organization's data, the database designer can eliminate data redundancies (needless repetitions) which are a key source for inaccurate information and ineffective systems.
2. Greater and advanced skills are adequate and required when data modelling project is done using packaged data model while fewer skills are required when data modelling is done without packaged data model.
HTML5
HTML5 has fewer plug-ins like the ability to standardize how audio and video are presented on a Web page. It introduces the <video> element designed to remove the need to install 3rd party add-ons and plug-ins like adobe flash player. It also adds the <audio> element too that allows pages to smoothly add audio files.
Answer:
True is the correct answer for the above question.
Explanation:
- The software is a collection of instruction which states the computer to how to do a specific work. The software developer only develops the software, but it is used by many users of the software who wants to do some specific task.
- The developer creates a graphical event for users through which the user can use the software of the computer system for his personal use.
- So the above line concludes that the software is for the user only. So the user interaction in software development is necessary which is also said by the question-statement. Hence the question statement is the true statement.
