Natural for Tamino

• The Idea
• / read employees from Tamino
• define data local
• using INS-EMP2
• end-define
• read ins-empl by name WOOLSEY
• print employee
• end-read
• end
• The Answer

Natural for Tamino

• DDM generation based on Tamino doctype (XML
  Schema)
• Xquery FLWR expression generated from Natural DML
  
• FLWR For Let Where Return
• FLWR example
• for x in input()/Employee
• let a x/Full-Name/Name
• let b x/Full-Adress/city
• where a gt WOOLSEY
• return ltMyOutputgtablt/MyOutputgt
• W3C standard Xquery does not define updates on
  node level
• Today Natural for Tamino doesnt support updates
  on node level
• However Insert, Delete, Replace is supported.

Natural for Tamino vs - Parse

• Natural for Tamino
• Characteristics
• Access through Naturals powerful, easy-to-use
  DML
• Interaction with business logic through Natural
  data structures
• Value
• No new skills required
• No third-party technology required
• Long-living and easy-to-maintain business logic
  (through database independence)
• Reduced development and maintenance costs

• Naturals Parse statement
• Characteristics
• Decomposes XML document into stream of tag/value
  pairs
• Is an integral part of the language
• Value
• Increased productivity during development
• High flexibility through independence from data
  structure
• Long-living and easy-to-maintain business logic
  (through platform independence)

13
Natural 6.1Enhanced Language

• PARSE Statement
• Example
• parse xml xml-data into path xml-path
• name
  xml-name
• value
  xml-value
• display xml-path (al60) xml-name (al15)
  xml-value (AL11)
• end-parse
• Example output

14
Natural 6.1Enhanced Language

• Dynamic Arrays
• Arrays of dynamic variables
• Arrays with dynamic number of occurrences
• DEFINE DATA LOCAL
• 01 DYN-ARR (A/110) DYNAMIC
• 01 DYN-GROUP (1)
• 02 NAME (A) DYNAMIC
• 02 AGE (N5)
• END-DEFINE
• Enhanced String processing
• EXAMINE - STARTING ENDING DIRECTION
• Function TRANSLATE Translate string to lower or
  upper case
• Function TRIM Remove leading and / or trailing
  blanks
• Large Constants and Init Values more than 253
  Bytes

15
Natural 6.1Enhanced Language

• Functions (procedures with return values)
• External / Internal Functions
• DEFINE FUNCTION name RETURNS var type
  DEFINE DATA PARAMETER ...
  END-DEFINEEND-FUNCTION
• DEFINE PROTOTYPE name RETURNS .... DEFINE
  DATA PARAMETER ...END-PROTOTYPE
• MOVE MY-FUNC (ltparm(), parm2gt) TO longtext
• Library SYSEXV, V6-FUNC (and V6-FUNCA)

16
Natural 6.1Change Enhancements

• Printing Treeview and Listview
• Fonts in data and program editor
• MINVAL / MAXVAL as system function
• Modifiable fields with edit masks
• Thousand separator
• Append work file
• FUNCTIONS
• New user interface for Debugger
• ...

17
Enhanced XML Toolkit

• Use new Natural features
• Parse Statement
• Dynamic arrays

• RESET INITIAL EMPLOYEE
• VALUE 'Employee/_at_Personnel-ID'
• EMPLOYEE.PERSONNEL-ID XML_VALUE
• VALUE 'Employee/Full-Name'
• IGNORE
• ...

19
