Concurrency Control in RDBMS

What are Transactions?

Transactions are sets of operations (like reading or writing data) treated as a single unit. Think of transferring money: multiple steps must happen together.

Isolation Levels

RDBMS uses isolation levels to manage how transactions interact:

• Read Uncommitted: Transactions see changes before they're finalized, which is risky due to potential inaccuracies.
• Read Committed: Transactions only see finalized changes, safer but still prone to inconsistencies.
• Repeatable Read: Data remains unchanged during a transaction, preventing some issues.
• Serializable: Transactions run sequentially, avoiding all problems but potentially slowing performance.

Techniques like locking data, timestamps,... Continue reading "Concurrency Control and ER Model in Database Systems" »

Hydro-Electric Power Plant

Classification of Hydro-Electric Power Plants

According to the Availability of Head:

1. Low head plants - head below 30 m
2. Medium head plants - head between 30 m to 180 m
3. High head plants - head 180 m and above.

According to the Nature of Load:

1. Base load plant
2. Peak load plant.

According to the Quantity of Water Available:

1. Run-off river plant without pondage.
2. Storage reservoir plant
3. Pump storage plant.

Such a plant has a large storage capacity of water; therefore, water collected in the rainy season is utilized during the dry period of the year.

The collection of water is done on a yearly basis; therefore, the capacity of the reservoir required is extremely large compared with the other types of hydroelectric power plants.

Constructor

A constructor is a special method in object-oriented programming that is automatically called when an instance (object) of a class is created. The main purpose of a constructor is to initialize the object's attributes (properties) and allocate resources if needed. Constructors have the same name as the class and do not have a return type.

Example of a Constructor

Here is an example in Python:

class Person:
    def __init__(self):
        self.name = "John Doe"
        self.age = 30

# Creating an instance of the Person class
person = Person()

print(person.name)  # Output: John Doe
print(person.age)   # Output: 30

In this example, __init__ is the constructor method in the Person class. It initializes the name and age attributes of the... Continue reading "Understanding Constructors and Class Variables in OOP" »

Manner and Form Requirements

Trethawon - The Privy Council upheld the manner and form of restriction on the Australian legislature. Even though it can be distinguished on the basis that, at the time, Australia had a colonial legislature as compared to New Zealand's sovereign Parliament.

Westco (HC) - Manner and form requirements can be applied (Obiter). At [93], McGechan J said, “While the point does not arise directly in this case, which is not a “manner and form” case but is a “content” case, I see no reason why the Court could not intervene in cases of non-compliance with the mandatory manner and form requirements as to passage of legislation at some suitable point before enactment.” If the content of the legislation offends, the...

Insertion Sort Algorithm

def insertion_sort(arr) :

for i in range(1, len(arr)):

key = arr[i]

j = i - 1

while j >= 0 and key < arr[j]:

arr[j + 1] = arr[j]

j -= 1

arr[j + 1] = key

# Example usage:

arr = [12, 11, 13, 5, 6]

insertion_sort(arr)

print("Sorted array is:", arr)

Binary Search Algorithm

def binary_search(arr, target):

left, right = 0, len(arr) - 1

while left <= right:

mid = (left + right) // 2

if arr[mid] == target:

return mid

elif arr[mid] < target:

left = mid + 1

else:

right = mid - 1

return -1

# Example usage:

arr = [2, 3, 4, 10, 40]

target = 10

result = binary_search(arr, target)

if result != -1:
