-------------Day-1 SQL----------
SQL is a standard language for accessing and manipulating databases.
โ What is SQL?
- SQL stands for Structured Query Language
- SQL lets you access and manipulate databases
- SQL became a standard of the American National Standards Institute (ANSI) in 1986, and of the International Organization for Standardization (ISO) in 1987
โ What Can SQL do?
- SQL can execute queries against a database
- SQL can retrieve data from a database
- SQL can insert records in a database
- SQL can update records in a database
- SQL can delete records from a database
- SQL can create new databases
- SQL can create new tables in a database
- SQL can create stored procedures in a database
- SQL can create views in a database
- SQL can set permissions on tables, procedures, and views
โ โ What Is a SQL Dialect, and Which one Should You Learn?
-----MySQL-----
MySQL is often compared to a handy free tool you might find in a toolbox. Imagine having a gadget that doesn't come with a price tag, yet is loved and recommended by many. That's MySQL for the digital world.

Day-1 Statistics
โ What is statistics?
Statistics is the study of the collection, analysis, interpretation, presentation, and organization of data. In other words, it is a mathematical discipline to collect, summarize data. Also, we can say that statistics is a branch of applied mathematics.
โ Why study statistics?
statistics is one of the most important things that you can study.
To be more specific, here are some claims that we have heard on several occasions. (We are not saying that each one of these claims is true!)
- 4 out of 5 dentists recommend Dentine.
- Almost 85% of lung cancers in men and 45% in women are tobacco-related.
- People tend to be more persuasive when they look others directly in the eye and speak loudly and quickly.
- Women make 75 cents to every dollar a man makes when they work the same job.
โ Common terms in Statistics!
1. Population
A population is a selected individual or group representing the full set of members of a certain group of interest.
2. Sample
A sample is a subset drawn from a larger population. If this drawing is accomplished in such a manner that each member of the population has an equitable chance of selection, the result is referred to as a random sample.
3. Parameters
A parameter is a value which is generated from a population. If I had all the data of all humans on Earth and generated the mean age, this value would be a parameter.
4. Statistics ๐
A statistic is a value which is generated from a sample

---------Day-2 of SQL-------------
โ What is a Database?
- Definition: A database is an organized collection of structured information or data, typically stored electronically in a computer system.
- Purpose: Databases are used to store, manage, and retrieve data efficiently.
โ What is DBMS?
- Definition: DBMS (Database Management System) is software that interacts with end-users, applications, and the database itself to capture and analyze data.
- Function: It provides a systematic way to create, retrieve, update, and manage data.
โ Features of DBMS
1. Data Integrity: Ensures accuracy and consistency of data.
2. Data Security: Protects data from unauthorized access.
3. Data Recovery: Provides mechanisms for data backup and recovery.
4. Data Independence: Separates data from application programs.
5. Concurrency Control: Manages simultaneous data access by multiple users.
6. Data Management: Facilitates data storage, retrieval, and update.
โ How Can We Interact with DBMS?
- SQL (Structured Query Language): The most common language used to interact with a DBMS for querying, updating, and managing data.
- Database Interfaces: Tools and applications (e.g., phpMyAdmin, pgAdmin) that provide a graphical interface to interact with the database.
- APIs: Application Programming Interfaces that allow software applications to interact with the DBMS programmatically.
โ What is a Query and Why is it Used?
- Definition: A query is a request for data or information from a database table or combination of tables.
- Purpose: Used to extract specific data by filtering, sorting, and presenting it based on certain conditions.
Example of a Query on Amazon
Extracting product details for all items in the "Electronics" category with ratings above 4 stars.
- SQL Example:
- Usage: This query helps Amazon identify and display high-rated electronic products to customers, enhancing user experience and satisfaction.

๐๐ป๐๐ป Statistics have majorly categorised into two types:
โ Descriptive statistics
โ Inferential statistics
๐Descriptive Statistics
In this type of statistics, the data is summarised through the given observations. The summarisation is one from a sample of population using parameters such as the mean or standard deviation.
Descriptive statistics is a way to organise, represent and describe a collection of data using tables, graphs, and summary measures. For example, the collection of people in a city using the internet or using Television.
๐ Inferential Statistics
This type of statistics is used to interpret the meaning of Descriptive statistics. That means once the data has been collected, analysed and summarised then we use these stats to describe the meaning of the collected data. Or we can say, it is used to draw conclusions from the data that depends on random variations such as observational errors, sampling variation, etc.

โ What is a Relational Database (RDBMS)?
A relational database is a type of database that stores and provides access to data points that are related to one another. Relational databases are based on the relational model, an intuitive, straightforward way of representing data in tables. In a relational database, each row in the table is a record with a unique ID called the key. The columns of the table hold attributes of the data, and each record usually has a value for each attribute, making it easy to establish the relationships among data points.
โ Relational terms
we need to know a few important terms. These are:
๐๐ป Relations โ Most of us know what a table is from using spreadsheet software. It is a grid made up of rows and columns. Well in relational databases we often refer to these as โrelationsโ.
๐๐ป Tuples โ A row in a table is known as a record, or a tuple. A tuple holds all the data on a single item.
๐๐ป Attributes โ An individual piece of data in a record is known as a field, or attribute.
Table Record Field
๐๐ป Domains โ All the possible allowable values for an attribute. This is slightly different to the data type of the attribute.
๐๐ป Cardinality โ How unique an attribute is in terms of its data values. Some attributes will have a wide range of different data values entered.
