The document outlines a Computer Programming 2 course, emphasizing the CRUD operations—Create, Read, Update, Delete—essential for managing data in databases. Led by instructor Mark John P. Lado, the course intends to equip students with knowledge on data handling within relational databases like Oracle and SQL Server. Assignments include exploring database definitions and types, with a focus on the importance of CRUD in transaction processing systems.

10. Objectives
Through a lecture-discussion, the students can:
1. describe what is a CRUD;
2. relate a TPS’s major operations;
3. assess the importance of CRUD in each TPS; and
4. explain how to use CRUD;

11. What is CRUD?
■ CRUD is an acronym that comes from
the world of computer programming
and refers to the four functions
that are considered necessary to
implement a persistent storage
application: create, read, update
and delete.

12. Explaining CRUD Operations
■ Organizations that keep track of customer
data, accounts, payment information,
health data, and other records require
data storage hardware and applications
that provide persistent storage. This data
is typically organized into a database,
which is simply an organized collection of
data that may be viewed electronically.

13. CRUD Databases and the Applications to
Manage Them
■ The CRUD acronym identifies all of
the major functions that are inherent
to relational databases and the
applications used to manage them,
which include Oracle Database,
Microsoft SQL Server, MySQL, SQLite
and others.

14. The four CRUD functions can be called by users
to perform different types of operations on
selected data within the database. This could
be accomplished using code or through a
graphical user interface.

15. The create function allows users to create a
new record in the database. In the SQL
relational database application, the Create
function is called INSERT. In Oracle HCM
Cloud, it is called create. Remember that a
record is a row and that columns are termed
attributes. A user can create a new row and
populate it with data that corresponds to
each attribute, but only an administrator
might be able to add new attributes to the
table itself.

16. The read function is similar to a
search function. It allows users
to search and retrieve specific
records in the table and read
their values. Users may be able to
find desired records using
keywords, or by filtering the data
based on customized criteria.

17. The update function is used to
modify existing records that
exist in the database. To
fully change a record, users
may have to modify information
in multiple fields.
UPDATE

18. The delete function allows users to remove
records from a database that is no longer needed.
Both SQL and Oracle HCM Cloud have a delete
function that allows users to delete one or more
records from the database. Some relational
database applications may permit users to perform
either a hard delete or a soft delete. A hard
delete permanently removes records from the
database, while a soft delete might simply update
the status of a row to indicate that it has been
deleted while leaving the data present and
intact.
