SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Edgar F. Codd[12] in the early 1970s.[13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM’s original quasirelational database management system, System R, which a group at IBM San Jose Research Laboratory had developed during the…

Complexity
SQL databases can be complex to set up and manage, requiring skilled database administrators to ensure optimal performance and maintain data integrity.
-
Limited Query Performance
SQL databases may have limited query performance when dealing with large datasets, as queries may take longer to process than in-memory databases.
-
Lack of Real-Time Analytics
SQL databases are designed for batch processing and do not support real-time analytics, which can be a disadvantage for applications that require real-time data processing.
-
Limited Flexibility
SQL databases are less flexible than NoSQL databases when it comes to handling unstructured or semi-structured data, as they require data to be structured into tables and columns.
-
Complex Interface –
SQL has a difficult interface that makes few users uncomfortable while dealing with the database.
-
Data Consistency
SQL databases ensure consistency of data across multiple tables through the use of transactions, which ensure that changes made to one table are reflected in all related tables.
-
Backup and Recovery
SQL databases have built-in backup and recovery tools that help recover data in case of system failures, crashes, or other disasters.
