Top 10 SQL concepts for data analysts 1. Database: A database is a structured collection of data that is organized and managed for easy access and retrieval. It stores data in tables, which are made up of rows and columns. 2. SQL (Structured Query Language): SQL is a programming language used to communicate with and manipulate databases. It allows data analysts to retrieve, insert, update, and delete data from a database. 3. Tables: Tables are the basic building blocks of a database. They consist of rows (records) and columns (fields) that store data in a structured format. 4. Queries: Queries are SQL statements used to retrieve specific data from a database. They can be simple or complex, involving multiple tables and conditions. 5. Joins: Joins are used to combine data from multiple tables based on a common field. They allow data analysts to retrieve related information from different tables in a single query. 6. Aggregation Functions: Aggregation functions, such as SUM, COUNT, AVG, MIN, and MAX, are used to perform calculations on groups of data. They are commonly used to summarize and analyze large datasets. 7. Filtering: Filtering allows data analysts to retrieve specific data based on certain conditions. It involves using the WHERE clause in SQL queries to specify the criteria for selecting records. 8. Sorting: Sorting allows data analysts to arrange data in a specific order. It involves using the ORDER BY clause in SQL queries to sort records based on one or more columns. 9. Subqueries: Subqueries are queries nested within another query. They allow data analysts to perform complex operations by using the results of one query as input for another query. 10. Data Manipulation Language (DML): DML statements, such as INSERT, UPDATE, and DELETE, are used to modify data in a database. Data analysts use these statements to insert new records, update existing records, or delete unwanted records ✅✅✅✅

In Python, data types are categories of values that determine what kind of operations can be performed on them. Python has several built-in data types that can be broadly classified into numbers, sequences, mappings, sets, and more. Here’s a breakdown of some common data types in Python: ### Numeric Types 1. int: Integer values.

    x = 10
    

2. float: Floating point numbers (decimals).

    y = 10.5
    

3. complex: Complex numbers with real and imaginary parts.

    z = 3 + 4j
    

### Sequence Types 1. str: String, a sequence of characters.

    s = "Hello, World!"
    

2. list: Ordered, mutable collection of items.

    lst = [1, 2, 3, "a", "b", "c"]
    

3. tuple: Ordered, immutable collection of items.

    tpl = (1, 2, 3, "a", "b", "c")
    

4. range: Sequence of numbers, often used in loops.

    r = range(1, 10)
    

### Mapping Types 1. dict: Collection of key-value pairs, unordered.

    d = {"name": "Alice", "age": 25}
    

### Set Types 1. set: Unordered collection of unique items.

    st = {1, 2, 3, 4, 5}
    

2. frozenset: Immutable version of a set.

    fs = frozenset([1, 2, 3, 4, 5])
    

### Boolean Type 1. bool: Represents True or False values.

    b = True
    

### None Type 1. NoneType: Represents the absence of a value.

    n = None
    

### Examples and Operations - int and float operations:

    a = 5
    b = 2.5
    c = a + b  # c is 7.5
    

- String operations:

    greeting = "Hello"
    name = "Alice"
    message = greeting + ", " + name  # message is "Hello, Alice"
    

- List operations:

    numbers = [1, 2, 3]
    numbers.append(4)  # numbers is now [1, 2, 3, 4]
    

- Dictionary operations:

    person = {"name": "Bob", "age": 30}
    person["age"] = 31  # Update value
    

- Set operations:

    set1 = {1, 2, 3}
    set2 = {3, 4, 5}
    union_set = set1 | set2  # union_set is {1, 2, 3, 4, 5}

Set up the folder structure as follows: src for Java source files WebContent for JSP files and static content (HTML, CSS, JavaScript) WEB-INF for web.xml and lib folder for dependencies

Hashing a password in Python can be efficiently done using the hashlib or bcrypt library. Here's a step-by-step guide for both methods: ### Using hashlib:

import hashlib

def hash_password(password: str) -> str:
    # Convert the password to bytes
    password_bytes = password.encode('utf-8')
    # Create a SHA-256 hash object
    sha256 = hashlib.sha256()
    # Update the hash object with the password bytes
    sha256.update(password_bytes)
    # Get the hexadecimal representation of the hash
    hashed_password = sha256.hexdigest()
    return hashed_password

# Example usage
password = "my_secure_password"
hashed = hash_password(password)
print(f"Original password: {password}")
print(f"Hashed password: {hashed}")

### Using bcrypt:

import bcrypt

def hash_password(password: str) -> str:
    # Generate a salt
    salt = bcrypt.gensalt()
    # Hash the password with the salt
    hashed_password = bcrypt.hashpw(password.encode('utf-8'), salt)
    return hashed_password.decode('utf-8')

def check_password(password: str, hashed: str) -> bool:
    # Check the password against the stored hash
    return bcrypt.checkpw(password.encode('utf-8'), hashed.encode('utf-8'))

# Example usage
password = "my_secure_password"
hashed = hash_password(password)
print(f"Original password: {password}")
print(f"Hashed password: {hashed}")

# To verify the password
is_correct = check_password(password, hashed)
print(f"Password is correct: {is_correct}")
