Final Product of this Course - Demo1:09
Simplified RDBMS5:08
Pre-Requisite Course2:46
Note : We dont need this library until section 8 - The Select queries.
Code Access4:39

Project Architecture6:53
Why We need Mexpr Library ?7:59
Understand why the RDBMS project relies on mathematical expression computations by showing how select clauses compute algebraic expressions, where clauses use logical expressions, and the library parses and evaluates them.
Select Query Execution Plan9:24
Memory Hungry SQL Queries4:49

Initializing Record Table2:52
We implement the record table for the employee SQL table using a B+ tree. If no primary key is provided, return an error and release allocated resources.
Understanding Database Layout ( Catalog Table )4:43
Mandatory Assignment
Implementing Database (Catalog Table)8:47
Assignment - Test your Implementation

Insert Into SQL Query - RoadMap5:26

Insert into Query - Data Collection4:00
Insert into Query - Algorithm Discussion12:34
Insert into Query - Algorithm Implementation9:52
Implement the sql insert operation by validating the catalog table, computing key and record sizes, building buffers, checking for duplicates, and inserting with success or error messages.

Testing the project at this point !1:33

Integrating Mexpr Library - Challanges3:29
In this section, we will going to integerate Mexpr Library which we developed in pre-prequisite course. For some notoriuous students, who may have not developed Mexpr Library fully or partially incomplete or buggy or for some reason not ready to use, they can integrate the pre-built Mexpr Library instead which is present in MathExpressionParser/libMexpr.a ( Oops branch only). Pls follow the same steps of integratation (though most steps are already done since it is pre-built library), the only difference is use path MathExpressionParser instead of MathExpressionParser/Course at all places. Though, you are strongly encouraged to use your invention only.

Last Step : Handling Lexical Stack5:42
Is your Calculator Application still working fine ?

Requirements

Should know basic SQL Queries or have some experience with SQL RDBMSs
well-verse with C/C++ programming languages, intermediate level of programming
Basic knowledge of Virtual Memory, and how malloc/free works
Zeal to learn instead of finding excused why not to do this course
Theoretical knowledge of B+ Trees ( why are they most suitable for RDBMS )

Description

** 29 DEC 2023 Under Dev **

This Course is about Learning Internal Design and Implementation of RDBMSs. Several times you have used RDBMSs and written a few SQL queries - but, never given a thought to how RDBMSs internally work. This Course is exactly about this.

This course is not about learning SQL queries or how to work with RDBMSs. This course is for developers.

We shall explore step by step - The Design, Implementation, Data Structures, and Algorithms in place which work together to make your SELECT queries work!

This Course Will be delivered as two courses - In the first Course (this course), we would implement a basic working RDBMS (PostgreSQL clone ) which can handle basic SQL select, create, insert, and delete queries. We will enhance the functionality further by supporting advanced features such as Aggregate functions, Joins, Where, and Group by Clauses. Nested Queries can also be supported. This RDBMS completely exists in RAM, and all data would vanish upon process termination.

In the sequel part of the course, We will take our RDBMS implementation onto the disk for persistent storage ( like real RDBMS do ) and also Implement other Database complexities such as Concurrnet readers/Writers , Write-Ahead-Logging ( WAL), Transactions, DB Update Hooks etc.

Talk to your prof - Do it as a Semester or Final year project. Best of luck!

Needless to say - This course is Advanced and for Champs who are chasing knowledge and excellence rather than degrees and jobs.

Warning: The Level of this course is intermediate to Advanced. Those who are still struggling with basic data structures, better excuse this course. You are expected to be thorough with Coding.

Who this course is for:

Students - Developer profile
Working Professionals
RDBMS developers or working on similar technologies
