Stored procedure is the pl-sql block in precomplile from and can be used to excecute plsql statement
They have data bases which are used and stored for information
Stored procedures prevent unauthorized access to data
DBMS procedures, or Database Management System procedures, refer to the set of predefined operations or functions that manage and manipulate data within a database. These procedures can include tasks such as data retrieval, insertion, updating, and deletion, as well as maintenance activities like backup and recovery. They are often implemented as stored procedures in the database, allowing for efficient execution of complex operations and ensuring data integrity. Additionally, DBMS procedures help standardize database interactions, making it easier to maintain and manage the data.
Procedures in an RDBMS are programs that are written to accomplish a set of functions that cannot be done using a single query. A procedure contains a sequence of SQL Queries that can be executed one after the other by invoking the procedure. There are two kinds of procedures Functions & Stored Procedures.
stored data is data that gets placed in different places on a computer but there is different types of stored data
1> Poor Exception handling 2>There are no debuggers available for stored procedures Siva.Pachigolla
data is stored in RAM modules
sp_helpdb , sp_who2, sp_renamedb are a set of system defined stored procedures. We can also have user defined stored procedures which can be called in similar way.
Most companies will have policies on how data should be stored, special attention should be paid to protect confidentiality of personal data. There are now many data protection laws in place, which need to be followed.
Data is stored on the hard disc. The more memory hard disc has the more data can be stored.
how data are stored would be in a physical layer
A trigger is a SQL procedure that initiates an action when an event (INSERT, DELETE or UPDATE) occurs. Triggers are stored in and managed by the DBMS.Triggers are used to maintain the referential integrity of data by changing the data in a systematic fashion. A trigger cannot be called or executed; the DBMS automatically fires the trigger as a result of a data modification to the associated table. Triggers can be viewed as similar to stored procedures in that both consist of procedural logic that is stored at the database level. Stored procedures, however, are not event-drive and are not attached to a specific table as triggers are. Stored procedures are explicitly executed by invoking a CALL to the procedure while triggers are implicitly executed. In addition, triggers can also execute stored procedures.Nested Trigger: A trigger can also contain INSERT, UPDATE and DELETE logic within itself, so when the trigger is fired because of data modification it can also cause another data modification, thereby firing another trigger. A trigger that contains data modification logic within itself is called a nested trigger.
