RAM and cache memory are examples of online storage as they provide direct and fast access to data. CD-ROM, floppy disk, and registers are examples of offline storage as they require external devices or are part of the processor's internal storage.

Online Storage:

1. RAM (Random Access Memory): RAM is a type of volatile memory that provides temporary storage for data and instructions while a computer is running. It is considered online storage because it is directly accessible by the computer's processor and allows for fast retrieval and modification of data.

2. Cache Memory: Cache memory is a small, high-speed memory located within the computer's processor or between the processor and the main memory. It is used to temporarily store frequently accessed data and instructions to speed up processing. Cache memory is considered online storage because it is directly connected to the processor and provides quick access to data.

Offline Storage:

1. CD-ROM (Compact Disc-Read-Only Memory): A CD-ROM is a type of optical disc that stores data and can only be read. It is considered offline storage because data is stored on the disc and requires a CD-ROM drive to read the information.

2. Floppy Disk: A floppy disk is a portable storage medium that uses magnetic storage to store data. It is considered offline storage because it requires a floppy disk drive to read and write data.

3. Registers: Registers are small, high-speed storage locations within the computer's processor. They hold data that is currently being used by the processor for arithmetic and logical operations. Registers are considered offline storage because they are part of the processor's internal storage and not directly accessible or removable.

When you filter a record, you hide some records and display others according to predetermined criteria. Both the records and the data within them are not permanently deleted from the document.

In Access databases, filtering is a helpful approach to display only the data you want to see. You can use filters to only print particular records from a report, table, or query or to display just particular records in a form, report, or query.

The act of selecting a smaller portion of your data set and using that subset for viewing or analysis is known as data filtering. Filtering is often only utilised temporarily; the entire data set is retained.

Data abstraction and data independence are two key concepts in computer science and database management systems. They are closely related and aim to improve the efficiency, flexibility, and maintainability of data management.

The definitions of these two are:

Data Abstraction:

Data abstraction refers to the process of hiding the implementation details of data and providing a simplified view or interface to interact with it. It allows users to focus on the essential aspects of data without being concerned about the underlying complexities. In programming languages, data abstraction is often achieved through the use of abstract data types (ADTs) or classes.

By abstracting data, programmers can create high-level representations of data entities, defining their properties and operations.

Data Independence:

Data independence refers to the ability to modify the data storage structures and organization without affecting the higher-level applications or programs that use the data. It allows for changes to be made to the database system without requiring corresponding modifications to the applications that rely on that data. Data independence provides flexibility, scalability, and ease of maintenance in database systems.

(a) To find all the candidate keys in R, we first need to find the minimal set of attributes that uniquely determine all the other attributes in the relation. These minimal sets of attributes are the candidate keys of the relation.

From the functional dependencies given, we can see that C and E determine D and D determines B. We can also see that C determines A. The combination of C and E will uniquely determine D, D and B and D, D, B and A, that's why C and E are candidate keys for the relation R.

In question (b) A relation is in 1st normal form (1NF) if it satisfies the rule that the values in each cell of a table must be atomic, meaning not a combination of other values. A relation is in 2nd normal form (2NF) if it is in 1NF and all non-key attributes are dependent on the primary key. A relation is in 3rd normal form (3NF) if it is in 2NF and it does not have transitive functional dependencies(FDs), meaning that any non-prime attribute (attribute that is not part of the candidate key) is non-transitively dependent on the primary key.

A relation is in Boyce-Codd Normal Form (BCNF) if it is in 3NF and all non-trivial FDs are determined by a superkey (candidate key).

Since the functional dependencies given (CE D, D B, C A) satisfies this definition, R is in BCNF.

(c) Since the relation is already in BCNF, there is no need to decompose it. However, if we have additional functional dependencies that are not in BCNF, we can decompose the relation until it becomes BCNF. This is done by identifying the non-trivial functional dependencies that violate BCNF and creating new relations based on them. Then, the new relations would be re-computed to ensure that they are in BCNF.

In , the best normal form for the given relation R is BCNF and it does not need to decompose since it does not have any transitive dependency, and all the functional dependencies are determined by the candidate key.

# Declare variables for largest and smallest

largest = None

smallest = None

# Prompt user to enter three integers

num1 = int(input("Enter first integer: "))

num2 = int(input("Enter second integer: "))

num3 = int(input("Enter third integer: "))

# Determine largest number

if num1 >= num2 and num1 >= num3:

   largest = num1

elif num2 >= num1 and num2 >= num3:

   largest = num2

else:

   largest = num3

# Determine smallest number

if num1 <= num2 and num1 <= num3:

   smallest = num1

elif num2 <= num1 and num2 <= num3:

   smallest = num2

else:

   smallest = num3

# Output results

print("The largest value is", largest)

print("The smallest value is", smallest)

```

In this program, the variables `largest` and `smallest` are declared and initialized to `None`. Three additional variables `num1`, `num2`, and `num3` are declared and initialized with integer values entered by the user using the `input()` function and converted to integers using the `int()` function.

The program then uses a series of `if` and `elif` statements to determine the largest and smallest of the three numbers, based on their values. The `largest` and `smallest` variables are updated accordingly.

Finally, the program outputs the results using two `print()` statements.v
