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.
Answer:
The missing code to this question is g.
Explanation:
In this question firstly import packages. Then declaration of the class Test that inherits the JApplet. In this class, we declare the default constructor. In this constructor, we call the add function. Then we declare another class that is SquarePanel. This class inherits JPanel. In this class, we define a method that is paintComponent(). In this method, we define an integer variable. In this method, we perform calculations and pass it to another function that is displaySquares(). In this function, we pass the value as the arguments. So in question the missing code or argument is g.
