Naming Conventions and Standards

• Database Object Name (i.e. Table, Sequence, View, Index, Trigger, Package, Procedure, Function, Materialized View, Job, Type, Directory, Constraints, Synonyms and Tablespace ) should be meaningful. Example : Table Name "HRS_EMPLOYEE_PERSONNEL"
• Column Name should be clearly defined and meaningful. Example : Employee_ID
• Database Object name and Column name should not contain the Number and Special characters except "_" character
• Constraints name should be clearly defined and must be used the prefix and suffix when creating the constraints

Constraints Name
Abbreviation	Description	Example
fk	References (Foreign Key)	hr_emp_empid_fk
uk	Unique Key	hr_emp_empid_uk
pk	Primary Key	hr_emp_empid_pk
ck	Check	hr_emp_empid_ck
nn	Not Null	hr_emp_empid_nn

• Use the following prefix in Identifier/Variable naming conventions (Local Variable, Global Variable, Parameter Variable, Constant Variable)

Abbreviation	Description	Example	Comment
k	Constant	k_mailhost	Generic constant
g	Variable	g_loop_count	Global (package-level) variable
v	Variable	v_loop_count	Local variable
p	Variable	p_loop_count	Parameter variable

• Use the following prefix for scalar types that have aggregate data types.

Abbreviation	Description	Example
c	Cursor	c_employees
cp	Cursor parameter	cp_employee_id
r	Record	r_employee

• The suffix is used to qualify the identifier further by documenting its usage. For example, the suffix denotes the type of parameter, whether IN, OUT, or IN OUT, or to show that a variable or parameter is also a table.

Type	Description	Example
	Input-only parameter	p_num_items
out	Output-only parameter	p_sum_out
inout	Both input and output	p_sum_inout

Product Naming Conventions and Standards
