It is a scripting language and a lightweight programming language in which it is possible to mix SQL easily. It is easy to install.ADP is base on Prolog. But ADP uses only the backtrack and unification. The syntax is original and likes a another scripting language, supports method call.This Webpage is made with ADP.Concept of ADPADP is being developed with the following concepts.-A multiparadigmlanguage based on logic programming-A lightweight scripting language-High affinity for SQL-Simple and familiar syntax-Not requires installation of complex procedures-Decent running speed-Supporting multi-processorsADP aims to be a powerful language that helps busy engineers .Tutorials (basic syntax)StringYou can define in C-style string by enclosing the string in double quotes ("). - If you want to put a double quotation in a string, you need to put \" in the string.- \" and \r and \n, \\ are the same way as C.You can define in BASIC-style string by enclosing the string in single quotes ('). - If you want to put a single quotation in a string, you need to put '' in the string.If a string contains new line, it is valid.Example"SELECT * FROM tab "VariablesA variable name has to start dollar $ sign.Example$x $valuePredicate(Like calling a function)Predicate is the ADP assessment unit.Write the following.　predicate_name(argment list)Exampleprint("Hello World")TermStrings and numbers, variables and predicate are called term.Goal cluase（Like a function body parts）Goal cluase has terms separated by commas "," and terminated by a semicolon ";".Goal clause is evaluated in the description of the order of source files by adp command.Example,print("Hello World");You input the source file above to adp command, then the command 'Hello World' on the screen. Horn clause（Like a function definition）　Horn clause has a horn head and a goal cluase.  The horn head begins from a "+" charactor and has horn_clause_name and argment lists. 　+horn_clause_name(argment list)goal_cluaseExample+horn_name($x,$y),print($x, '=', $y);CommentsA comment begins from a '#' character and ends to the end of the line.,printn("Hello World"); # Here is a comment.Tutorials (example of code）Hello Wold・program code（helloworld.p）,printn("Hello World.");・example of the executionD:\sample>adp helloworld.pHello World.ADP command loads and compiles the program. Then, ADP evaluates goal clauses, executes the program.This sample, hellowrld.p, is evaluating predicate of 'printn'.　 'printn' is one of the embedded predicate, l
