Answer:
Database.
Explanation:
A database is a structured collection and gathering of data, usually stored and later used electronically from a computer system. Whenever there’s a complexity in databases then there are mostly developed using formal design and some advanced modeling techniques.
It is a system built for storing and managing data (every kind of information). A database machine is capable of sorting, changing or serving the information on the database. The information itself can be kept in many diverse ways - prior to digital computers, printed books, card files, and other methods were used.
Answer:
B. Methods and occasionally final attributes
Explanation:
In Computer programming, class members can be defined as the members of a class that typically represents or indicates the behavior and data contained in a class.
Basically, the members of a class are declared in a class, as well as all classes in its inheritance hierarchy except for destructors and constructors.
In a class, member variables are mainly known as its attributes while its member function are seldomly referred to as its methods or behaviors.
One of the main benefits and importance of using classes is that classes helps to protect and safely guard their member variables and methods by controlling access from other objects.
Therefore, the class members which should be declared as public are methods and occasionally final attributes because a public access modifier can be accessed from anywhere such as within the current or external assembly, as there are no restrictions on its access.
<span>With the use of a database application people can store and retrieve large quantities of data almost instantaneously. Database applications can also be used to present the information in easy to read and understand forms. Database applications serve as an intermediary between the raw data and a user, making it easier to sort and use the data.</span>
Answer: Environment sensing Collector
Explanation:
An environmental monitoring system or collectors is the process which a device uses in monitoring the quality of the environment. These devices or software allows for a realtime monitoring and checking of any parameter required. They are used to monitor and collect data on environmental conditions such as relative humidity, temperature, dew and frost point, differential pressure, pressure, flow, and many more.
