What are the features of embedded SQL? Explain.
Embedded SQL - SQL could be implemented within two ways. It can be used interactively or embedded in a host language or through using API. The use of SQL commands inside a host language (e.g., C, Java, etc.) program is known as embedded query language or Embedded SQL. While same capabilities are supported for a variety of host languages, the syntax sometimes varies. A few of the features of embedded SQL are:
SQL statements could be used while a statement in the host language is permitted. It merges the strengths of two programming environments, the procedural characteristics of host languages and non-procedural character of SQL.
SQL statements could refer to variables (must be prefixed by a colon in SQL statements) described in the host program.
Special program variables (known as null indicators) are used to assign and retrieve the NULL values to and from the database.
The facilities available by the interactive query language are also mechanically available to the host programs.
Embedded SQL along with host languages could be used to accomplish extremely complex and complex data access and manipulation tasks.
What are axioms? Axioms or rules of inference give a simpler technique for reasoning about
