  2. What is AtomBox Out of the box solution for quick and easy data access

  3. Key components • Atom/Box Data Model • AtomBox Script

  4. AtomBox Data Model Understands your data

  5. Atom/Box Data Model • Atom – the data unit • Holds a value – the smallest logical data unit • Packs (consumes)binary data into the internal storage • Unpacks the internal storage into binary data • Does validation against defined constraints • Has internal states – OK, WARNING, ERROR, DEFAULT • Emits SIGNALS – when packed, unpacked, value/state changed

  6. Atom/Box Data Model • Box – The container • Container of other Boxes and Atoms (does not hold a value) • Packs (consumes)binary data into the contained atoms and boxes • Unpacks the model into a binary data • Has internal states – OK, WARNING, ERROR, DEFAULT (all depending on its Atoms/Boxes it contains) • Emits SIGNALS – when packed, unpacked, value/state changed

  7. Atom/Box DDL • Textual Domain Specific Language aiming at describing any kind of data. • Compatible with HP NonStop DDL • Custom DDL language extensions for dynamic data: • VLENGTH DEPENDING ON • VLENGTH DELIMITED BY • ISOBITMAP • CHOICE – speculative parsing • EBCDIC – character set • Others. • Direct mapping to an Atom/Box Data Model

  8. Other Atom/Box mappings • ACI’s metadata storage CSV – file • Generated by MetaMan utility • Direct mapping to an Atom/Box Data Model • Further possible improvements includes: DFDL for IBM – Message Broker, or a Graphical DSL

  9. { workflow: { }<16><OK>, recordType_mb: {DBTRAN21}<8><Warning>, dataSpecificationVersion: {2.4 }<5><OK>, clientIdFromHeader: {FDI_00000118 }<16><OK>, recordCreationDate: { yyyy: {2014}<4><OK>, mm: {1}<2><OK>, dd: {29}<2><OK> }, recordCreationTime: { hh: {13}<2><OK>, mm: {38}<2><OK>, ss: {7}<2><OK> }, recordCreationMilliseconds: {675}<3><OK>, gmtOffset: {0}<6><OK>, customerIdFromHeader: { }<20><OK>, customerAcctNumber: { }<40><OK>, externalTransactionId: {140129143803 000029133807}<32><OK>, pan: {0005573510608683144}<19><OK>, authPostFlag: {A}<1><OK>, cardPostalCode: { }<9><OK>, cardCountryCode: { }<3><OK>, openDate: { }<8><OK>, plasticIssueDate: { }<8><OK>, cardExpireDate: { yyyy: {2015}<4><OK>, mm: {1}<2><OK>, dd: {1}<2><OK> }, transactionDate: { yyyy: {2014}<4><OK>, mm: {1}<2><OK>, dd: {29}<2><OK> }, transactionTime: { hh: {13}<2><OK>, mm: {38}<2><OK>, ss: {7}<2><OK> }, transactionAmount: {0}<13><Warning>, transactionCurrencyCode: {826}<3><OK>, transactionCurrencyConversionRate: {0}<13><OK>} userData01: { ref_anti_ref_days: { }<3><OK>, vac_cntry_cd: { }<3><OK>, user_ind_4: { }<2><OK>, card_act_stat: { }<1><OK>, ed_card_tech: {1}<1><OK> }, userData02: { acct_block_code_1: { }<1><OK>, acct_block_code_2: { }<1><OK>, card_block_code: { }<1><Warning>, bs_user_field_50: { }<1><OK>, amed_fraud_monitor: { }<2><OK>, some_filler: { }<4><OK> ……… Atom/Box model

  10. No data model is complete without an easy way of accessing it.

  11. A different approach: Interpreting vs Generating

  12. AtomBox Script Do more with less code

  13. Functional vs Imperative programming • Imperative programming • You tell the computer WHAT to do • Functional programming • You DESCRIBE what you want rather HOW you want something done

  14. JavaScript – The (only) language of the Web now coming to the Server • One of the world most popular language • Part of the WEB 2.0 revolution • Functional programming paradigm • Easy to use • Unlimited talent pool available • Built with the latest technologies (QT and C++)

  15. AtomBox Script • Based on the latest ECMA standards • Direct mapping from Atom/Box data models to JavaScript classes (Atom/Box instances) • Runs on multiple platforms: • UNIX, HP NonStop – Guardian and Windows • Asynchronous and event based • Remote debugging capabilities

  16. AtomBox Script (cont) • Full set of cross-platform API’s for: • Binary classes and streams • Accessing file systems and processes, terminals • Cryptography (including EFT modules) • TCP/IP Networking – including a TCP/IP server • Built-in WEB server for creating WEB Services • SQL module • XML • Extensive documentation

  17. AtomBox Script examples: !file helloddl! DEFINITIONHelloClass.     02 message.         04 part1 PIC X(5).         04 part2 PIC X(5) DEFAULT "world" MUST BE "world". END. var console = require("console"); //load the ddl that describe the message var Hello = require("helloddl","ddl").HelloClass; var o = new Hello(); //create an object of class Hello o.message.part1.value = "Hello"; //change the value of the part1 //unpack the message, decode the resulting ByteArray to a String //and invoke the `write` function on the 'console' object console.write(o.unpack().decodeToString());

  18. AtomBox Script examples: // //  TCP/Server Server example // var net     = require("net"); var server =  newnet.TcpServer(); server.listen(8150); // Connect the newConnection signal server.newConnection.connect(function() { // Accept the client connection     var client = server.nextPendingConnection();     client.write(“Hello World!”.toByteArray()); // Wait for the server to send the message and then disconnect     client.bytesWritten.connect(function() {          client.disconnectFromHost(); //close the connection     }); });
