Depends, what language?
New, compared to what? I guess you meant user-defined data-types, which exist in almost every modern programming language.
Because that is how the language is defined. It has floating data types and integral data types.
What are language design requirements for languages that support abstract data types ---- Is something that you will find in your text book or ask your teacher. WikiAnswers cannot do your homework for you.
In c language data types are used to specify the tye of data.for ex:int a;It means "a" is a variable of type integer.There are two types of data types in c.They areprimary data typessecondary data typesprimary data types are the built in data types and secondary data types are the user defined data types.eg for primary data types are int,float,char,long,double..and for secondary are arrays,structures,pointers,unions..
C is called a middle level language since it is a higher language than something like assembler, which communicates to the computer through operations that directly manipulate data and uses machine code.High level languages, are very close to human readable/speakable languages, such as English and French ( and many more), and are therefore more human-oriented.Unfortunately, the C programming language is neither a low-level language, such as assembler, or a high level language such as English, but somewhere in between. Thus a middle-level languageBy mistake. It is a high-level language.

The ranges for all data types in C are implementation-defined.
Because that is how the language is defined. It has floating data types and integral data types.
SQL in database is short for structured query language. There are four types of SQL statements which are as follows : 1) Data retrieval language 2) Data manipulation language 3) Data control language 4) Data definition language
If an object oriented language supports the concept of primitive data types then the language is not a pure. C++ is not pure because it supports raw data pointers and fundamental types like int and float, none of which have member methods associated with them. Java, on the other hand, is pure object oriented because it has no primitive data types; all types are implemented as objects. Java is therefore easier to use than C++, but is less efficient because it provides no low-level interaction with the machine.

In a computer language, Primitive data types are the fundamental or built-in data types the language will manipulate without a subroutine call, type modifier, or object. For example, in C they are: int, char, float, and double. In Java they are: byte, short, int, long, float, double, Boolean, and char. Below the language level, Primitive data types are that which are supported or implemented directly in hardware or through microcode. For example, some computers directly handle strings with length up to the database record capacity through microcode. These Primitive types can be combined with type modifiers for Int (short, long), pointers, arrays, structs, and unions into many different "complex" data types handled by the programming language.
a composite data type is any data type which can be constructed in a program using its programming language's primitive data types and other composite types. The act of constructing a composite type is known as composition.
primary datatypes means the data types which are provided by developer of language himself like int,float,double,char are the primary data types in c language where as the String,array are nothing but the derived data types. for Ex.we derived the String data type from char datatype using array system.

Presentations do not have data-types, you might have misunderstood somethings.
