Doctype helps the web browser to correctly render the web pages. There are different types of Doctype that are available and they are as follows:


=> Strict Doctype: it consists of all the HTML elements and it is also known as DTD (Document type definition) but it doesn't include the presentational and deprecated elements i.e. font, center, etc. Framesets related elements are also not allowed in this. For example:


<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"

Q:

What is a Collection? Explain collection types.

Answer

A collection just like an array is an ordered group of elements of the same type. Each elements position is determined by a unique subscript.


 


Index by tables:- They are similar to hash arrays that allows to search for subscript values using arbitrary numbers and strings.


They can be declared as:


TYPE type_name IS TABLE OF element_type [NOT NULL]


INDEX BY [BINARY_INTEGER | PLS_INTEGER | VARCHAR2(size_limit)];


INDEX BY key_type;


Example:


TYPE studenttyp IS TABLE OF emp%ROWTYPE


INDEX BY BINARY_INTEGER;


stud_tab studenttyp;


 


Nested tables:- they hold random number of elements and use sequential numbers as sub scripts.


They can be declared as:


TYPE type_name IS TABLE OF element_type [NOT NULL];


Example: TYPE employee_type IS TABLE OF NUMBER INDEX BY VARCHAR2(64);


 


Varrays: Holds a fixed number of elements which can be changed in run time. 


They can be declared as:


TYPE type_name IS {VARRAY | VARYING ARRAY} (size_limit) OF element_type [NOT NULL];


Example: TYPE Calendar IS VARRAY(366) OF DATE;
