What is SQL? and History of SQL?

 

What is SQL?

  • SQL stands for Structured Query Language and is a Programming language.
  • SQL is used to manage and manipulate relational databases.
  • SQL is a tool for organizing, managing, and retrieving archived data from a database.

History of SQL?

In June 1970, Dr. E. F. Codd published the paper, “A Relational Model of Data for Large Shared Data Banks,” in the Association of Computer Machinery (ACM) journal, Communications of the ACM.

Codd’s model, now accepted as the definitive model for relational database management systems (RDBMS), inspired the development of the language Structured English Query Language (SEQUEL) by IBM Corporation, Inc.

SEQUEL, later known as SQL (still pronounced “sequel”), was designed to implement Codd’s model. In 1979, Relational Software, Inc. (now Oracle), introduced the first commercially available implementation of SQL.

Oracle Database 19C Performance Tunning - PART 1

Advantages: 1. Improved Query Performance •    Optimized SQL execution plans lead to faster query response times. •    Reduces unnecessary full table scans and improves indexing strategies. •    Parallel execution tuning speeds up large data processing tasks. 2. Better Resource Utilization •    Efficient use of CPU, memory, disk I/O, and network resources. •    Reduces contention on Redo Logs, Undo Tablespaces, and Buffer Cache. •    Helps in load balancing across multiple instances in RAC (Real Application Clusters). 3. Increased System Scalability •    Ensures that the database can handle a growing number of users and transactions. •    Proper tuning allows scaling without degrading performance. •    Optimized parallel processing ensures better performance on multi-core servers. 4. Lower Infrastructure Costs •    Reduces the need for add...

Oracle RMAN Backup And Restore

RMAN: (Oracle 8) RMAN (Recovery Manager) is a utility provided by Oracle Database to perform backup, restore, and recovery operations. It is a command line tool. Features of RMAN in Oracle 19c Comprehensive Backup Capabilities: Full and incremental backups. Block-level backups for efficient data storage. Archived redo log backups. Fast Recovery Area (FRA) integration for centralized backup storage. Efficient Recovery Options: Point-in-time recovery (PITR). Complete and incomplete recovery. Flashback database capabilities for quick undo of changes. Multitenant Database Support: RMAN fully supports container databases (CDBs) and pluggable databases (PDBs). Provides flexibility to back up and recover individual PDBs or entire CDBs. Automatic Space Management: Manages disk space in the FRA. Automatically deletes obsolete backups and archived logs. Data Deduplication and Compression: Backup optimization through block-level deduplication. Built-in compression algorithms to reduce storage req...
