Answer:
"Option b and Option d" is the correct option for this question.
Explanation:
In the database, datatype belongs to the information storage medium, which can hold a specific type of value. There are several data types, which is used in database like integer, character, series, floating-point and array numbers, and the rules, that give levels of security to information are known as a security constraints. It may be either developed as rules on integrity, mathematical formalism rules or schematic rules, and other choices were wrong which can be described as follows:
- In option a, The asserts, which is in any exchange in a database, should only modify the information, that is effected in acceptable ways is called consistency, that's why it is wrong.
- In option c, The validity and accuracy of the data in the database can not be ensured, that's why it is wrong.
The responsibility for failures was deflected away from the automated parts of the system (and the humans, such as engineers, whose control is mediated through this automation) and placed on the immediate human operators, who possessed only limited knowledge and control.
The answer to this is C :D
Answer: Determine the most popular solution.
Explanation:
Some of the approaches to problem solving that are listed here include:
• Gather data and verify the most likely causes.
• Revise the project plan.
• Evaluate the alternative solutions
To solve a problem, one needs to gather the data and verify the likely causes of the problem. This can be done by asking questions, running test, interviewing people, running tests, reading reports, or analyzing data.
The project plan can also be revised. Likewise, when one comes with different solutions, one should weigh the cost and benefits of each in order to choose the best solution.
Determine the most popular solution isn't a correct option.
Answer:
A BorderLayout corresponds to a layout type where the components are organized along geographical directions represented by NORTH, SOUTH, EAST, WEST, and CENTER.
Explanation:
The layout class is awt determines the actual placement of components in the user interface. BorderLayout is a layout where the components are organized along geographical directions represented by NORTH, SOUTH, EAST, WEST, and CENTER. For example:
Panel p = new Panel();
p.setLayout(new BorderLayout());
p.add(new TextArea(), BorderLayout.CENTER);
p.add(new Button("Close"), BorderLayout.SOUTH);
This code segment will add a textarea at the CENTER of the interface and a button 'Close' towards the SOUTH.
