String data type allows unlimited character intput
When we enter a variable then we know it what type it belong ,but the compiler does not know it ,for knowing it we declare data types. Storage representations & machine instructions to handle constants differ from machine to machine.The variety of data types available allow the programmer to select the type appropriate to the needs of the application as well as the machine. ANSI C supports 3 types of data types 1.Primary data types 2.Derived data types 3.User defined data types JAVA has 2 types 1.In Built data types 2.User Defined datatypes
All built-in data types are not abstract data types.
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..

BLOB = (Binary Large OBject) An Oracle BLOB data type that contains binary data with a maximum size of 4 gigabytes. This maps to an Array of type Byte. See also: CLOB, NCLOB An Oracle CLOB data type that contains character data, based on the default character set on the server, with a maximum size of 4 gigabytes. This maps to String. An Oracle NCLOB data type that contains character data, based on the national character set on the server with a maximum size of 4 gigabytes. This maps to String.
SQL server data types include integer, character, date and time, monetary, and binary strings. These types are divided into groups including approximate numerics, exact numerics, character strings and unicode character strings.
Data entry is the process of transcribing or copying data from usually a paper source into a computer or information system. This is done by a person manually using specialized tools (e.g. a keyboard or scanner). Data can consist of text, numeric, audio, video, or other types. Data entry has two contradictory goals: * maximum accuracy (entry with minimal errors), and * maximum speed (greatest number of data per hour or minute).

Spreadsheets generally accept two fundamental types of data: constant data, such as a constant number, date, time or text, or formulas. Formulas produce data of the same data types (e.g. text, number, date, time, etc), but are evaluated dynamically.
text is a default data type that allows and support any kind of data character digit and special character it store alphanumeric values up to 255 characters a memo store data up to 2GB and it has maximum length of 65,536 character notes
Integer types, floating point types, Boolean types, character types, string types, pointer and array types, reference types, enumeration and other user-defined types.
The primitive data types that can normally be represented and processed by a CPU are an integer, real number, character, Boolean, and memory address
The alphanumeric keyboard is used for data entry. One types to enter data into the computer. Keyboards that look like piano keys are used to enter notes into an electronic device that plays or stores music.
Java has a total of 8 primitive data types# byte: The byte data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). # short: The short data type is a 16-bit signed two's complement integer. It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive) # int: The int data type is a 32-bit signed two's complement integer. It has a minimum value of -2,147,483,648 and a maximum value of 2,147,483,647 (inclusive). # long: The long data type is a 64-bit signed two's complement integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (inclusive). # float: The float data type is a single-precision 32-bit IEEE 754 floating point. # double: The double data type is a double-precision 64-bit IEEE 754 floating point. # boolean: The boolean data type has only two possible values: true and false. # char: The char data type is a single 16-bit Unicode character. It has a minimum value of '\u0000' (or 0) and a maximum value of '\uffff' (or 65,535 inclusive). In addition to the eight primitive data types listed above, the Java programming language also provides special support for character strings via the java.lang.String class. Enclosing your character string within double quotes will automatically create a new String object;For ex: String name = "Rocky"; would create a new String object of name "name" and holding an initial value "Rocky"
