Don't forget to understand these essential SQL topics if you're just starting out.
1. SQL Basics
- SELECT Statement:
It's like asking the database for specific information.
- FROM Clause:
Tells the database where to look for that information.
- WHERE Clause:
Filters out the stuff you don't need.
- ORDER BY Clause:
Arranges the results in a specific order.
2. Data Manipulation
- INSERT: Adds new data.
- UPDATE: Changes existing data.
- DELETE: Removes data.
- MERGE: Combines these actions.
3. Data Definition
- CREATE TABLE: Makes a new table.
- ALTER TABLE: Edits an existing table.
- DROP TABLE: Deletes a table.
- INDEXES: Helps with finding data quickly.
4. Constraints
- PRIMARY KEY: Ensures each row is unique.
- FOREIGN KEY: Keeps data relationships intact.
- UNIQUE: Ensures values are unique.
- DEFAULT: Sets a value if none is given.
5. Joins (Really Important)
- INNER JOIN: Combines data from different tables.
- LEFT JOIN: Gets all data from one table and matching data from another.
- RIGHT JOIN: Opposite of LEFT JOIN.
- FULL JOIN: Gets data if it's in either table.
- SELF JOIN: Links data within the same table.
6. Subqueries:
- Correlated Subqueries: Subqueries connected to the main query.
- Scalar Subqueries: Subqueries that return a single value.
- Subquery in FROM Clause: Using a subquery as a table.
7. Aggregation Functions:
- SUM, COUNT, AVG, MAX, MIN: Math on groups of data.
- GROUP BY: Groups data before doing math.
- HAVING: Filters groups based on math results.
8. Views:
- CREATE VIEW: Makes a pretend table.
- ALTER VIEW: Changes the pretend table.
- DROP VIEW: Deletes the pretend table.
9. Transactions:
- BEGIN TRANSACTION, COMMIT, ROLLBACK: Ensures data stays safe and consistent.
- ACID Properties (Important): Rules for safe transactions.
10. Database Security:
- GRANT and REVOKE: Decides who can do what.
- Roles: Groups of permissions for users.
11. Normalization (Important):
- 1NF, 2NF, 3NF, BCNF, 4NF:
Ways to organize data for efficiency and accuracy.
12. Indexes:
- Clustered vs. Non-Clustered Indexes: Different ways to find data quickly.
13. Database Management Systems (DBMS):
- Different software tools for working with databases, like MySQL etc.

6. /lib: Shared libraries (similar to Windows DLLs) that programs can use are stored here. Examples are
7. /mnt: This directory is often used as a mount point for temporary filesystems.
8. /opt: Additional software packages and applications that are not part of the core system can be installed here. Each package may have its own subdirectory, like
9. /proc: A virtual filesystem that provides information about running processes and system status.
10. /root: The home directory for the root user.
11. /sbin: System binaries essential for system administration, like
12. /srv: This directory is typically used for data served by the system.
13. /sys: Another virtual filesystem that provides information about kernel and devices.
14. /tmp: Temporary files are stored here. They are usually cleared on system startup.
15. /usr: This directory contains user programs and data.
- /usr/bin: User-level command binaries.
- /usr/include: Header files for C/C++ libraries.
- /usr/lib: Libraries for programming and software.
- /usr/local: Software manually installed by the system administrator.
16. /var: Variable data that changes frequently.
Overall, this file system structure reflects a standard layout found in many Linux distributions, with key directories serving specific purposes, from system binaries to user files, libraries, configuration, and temporary data. Keep in mind that while this is a general representation, individual distributions might have variations or additional directories based on their design and purpose.

---------------------------
1. /boot: This directory contains essential files for booting the system.
2. /bin: Basic system binaries reside here, such as common command-line utilities like
ls, mkdir,
and cp.
3. /dev: This directory contains device files that represent various devices connected to the system, such as hard drives (`sda`,
sdb`) and pseudo devices like `null.
4. /etc: Configuration files for the system and installed applications are stored here. Examples include
fstab
(filesystem table), hostname
(system's hostname), passwd
(user account information), sudoers
(sudo configuration), and nginx .conf
(configuration for the Nginx web server).5. /home: User home directories are typically found here. Examples include
user1, user2,
and user3,
each with their files and settings.6. /lib: Shared libraries (similar to Windows DLLs) that programs can use are stored here. Examples are
libcrypto .so
and libssl .so.
7. /mnt: This directory is often used as a mount point for temporary filesystems.
8. /opt: Additional software packages and applications that are not part of the core system can be installed here. Each package may have its own subdirectory, like
app1
and app2.
9. /proc: A virtual filesystem that provides information about running processes and system status.
10. /root: The home directory for the root user.
11. /sbin: System binaries essential for system administration, like
init
(the first process) and shutdown
(to shut down the system).12. /srv: This directory is typically used for data served by the system.
13. /sys: Another virtual filesystem that provides information about kernel and devices.
14. /tmp: Temporary files are stored here. They are usually cleared on system startup.
15. /usr: This directory contains user programs and data.
- /usr/bin: User-level command binaries.
- /usr/include: Header files for C/C++ libraries.
- /usr/lib: Libraries for programming and software.
- /usr/local: Software manually installed by the system administrator.
