SQL (Structured Query Language) is a powerful domain-specific language designed for managing and manipulating relational databases. It allows users to define, query, and manipulate data in a relational database management system (RDBMS). SQL consists of various commands, such as SELECT, INSERT, UPDATE, and DELETE, enabling users to interact with databases efficiently.
PL/SQL (Procedural Language/SQL) is an extension of SQL developed by Oracle. It integrates procedural constructs with SQL, allowing for the creation of stored procedures, functions, and triggers. PL/SQL enhances the capabilities of SQL by providing procedural programming features like loops, conditional statements, and exception handling. This enables the development of more complex and dynamic database applications.
DBMS (Database Management System) is a software suite that facilitates the creation, management, and interaction with databases. It provides an interface for users and applications to interact with the database, ensuring data integrity, security, and efficient data retrieval. Popular relational database management systems include Oracle Database, MySQL, Microsoft SQL Server, and PostgreSQL.
In summary, SQL is the language used to communicate with databases, PL/SQL extends SQL by adding procedural programming capabilities, and a DBMS is the overarching software that manages databases, ensuring optimal organization and retrieval of data. Each component plays a crucial role in the efficient and secure operation of database systems.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
