  1. >Opening I-4GL Applications to Maximizing IT Assets Expanding Market Opportunities

  2. 4GL Business Applications • Mature, Robust, Scalable • Feature Rich, Easily Adapted • 10x Developer Productivity So What’s The Problem?

  3. Challenges • Rapidly changing infrastructure drives new deployment requirements • First Windows (1980s) • Then Web (HTML – 1990s) • Then Java • Now Mobile (PDAs, WAP) • Then What?

  4. Challenges … • Not to mention • OS Support … • First numerous Unix platforms • Then NT • And Linux finally appears here to stay • And, of course, what we’re here to focus on • What Database has your IT organization or customer decided on Today?

  5. 4Js in a Nutshell Four J’s enables rapid, low cost evolution of business applications to support Windows, the Internet, and Mobile Devices Any Database Across 18+ Operating Systems Providing you with maximum ROI and competitive leverage of your business applications

  6. Four J’s - Architecture

  7. 4J’s Development Tools Provide all the essential elements needed to easily migrate Informix 4GL applications to……

  8. We’ve done this before! Four J’s provides an Adaptation Guide and conversion tools specific to each of the major database engines. The guides contain detailed technical information with compatibility issues and conversion rules.

  9. The process is straightforward • Prepare Oracle and the data schema • Migrate the data • Setup database connectivity • Clean up proprietary SQL statements • Re-compile and test 4GL programs

  10. SMALLINT NUMBER(5) • INTEGER NUMBER(10) • DECIMAL(p,s) NUMBER(p,s) • MONEY(p,s) NUMBER(p,s) • CHAR(n) CHAR(n) (max = 2000 c) • VARCHAR(n) VARCHAR2(n) (max = 4000 c) • DATE DATE (year to second) • DATETIME DATE (year to second) • FLOAT NUMBER • SMALLFLOAT NUMBER Type conversion is automatic • Unsupported : INTERVAL, BYTE, TEXT, NCHAR, NVARCHAR

  11. Proprietary SQL is emulated • Transactions commands and auto-commit mode (begin work,…) • Temporary tables (create temp table… &select… into temp) • Scroll cursors (declare c scroll cursor for select…) • Insert cursors (declare c cursor for insert…) • Cursors declared “with hold” (transaction independent) • Positioned updates and deletes (where current of) • The SERIAL data type (sqlca.sqlerrd[2] supported) • OUTER joins (select…from tab1, outer(tab2)) • Column subscripts (colname[2,10]) • MATCHES operator (…where custname matches “A*”) • Double quoted string are converted to single quoted strings • Some SQL functions (today, current,…)

  12. 4Js supports proprietary SQL • SQL Blocks • SQL Directives 4Js also supports database-specific SQL through new 4GL features:

  13. Blocks allow proprietary SQL SQL Blocks • SQL syntax independent from the 4GL grammar • Opens 4GL to any SQL Language MAIN DATABASE stores DECLARE c1 CURSOR FOR SQL SELECT name, address, cdate FROM customer WHERE custid = $p_num END SQL OPEN c1 ... END MAIN

  14. SQL Directives control.. ..which SQL is used with which database • Purpose: Control the SQL text sent to the database server • Based on special comments {% …} • Kind of Macros for SQL statements • Customizable (defined externally in FGLPROFILE) Syntax: {% <directive name> [ <param> …] } Examples: {% IFDEF IFX “OUTER(order)” “order” } {% YEAR “order_date” }

  15. SQL Directives are supported in.. ..Dynamic SQL PREPARE s1 FROM “SELECT … FROM order AND{% YEAR \”ord_date\” }= ?” DECLARE c1 CURSOR FOR s1 OPEN c1 USING p_year • Some limitations: • Not supported in Static SQL (=part of 4GL grammar) • Cannot be nested ({% IFDEF IFX {% …} …})

  16. As are Blocks SQL Directives: Using SQL Blocks DECLARE c1 CURSOR FOR SQL SELECT … FROM customer,{% IFDEF IFX “OUTER(order)” “order”} WHERE{% IFDEF IFX “cust_num = ord_num”} {% IFDEF MSV “cust_num *= ord_num”} {% IFDEF ORA “cust_num = ord_num(+)”} AND{% COLSUBSTR cust_type 2 3}= ‘CF’ AND{% YEAR ord_date}= $odate END SQL The power of SQL Directives: Make 4GL programs speak any SQL dialect.

  17. The Value of 4Js • Rapidly Deploy your I4GL applications • On Oracle and other databases • On Windows, the Web, and Mobile Devices • Leverage your application’s mature, robust, feature rich code base • Save Millions in development and deployment • Millions less costly than re-engineering • Leverage existing staff and applications • It’s a predictable, safe upgrade path • With lower deployment costs

  18. The Application: Government and School Administration The Business Need: Competitive requirement to move to Windows and NT Must retain their product’s mature, feature rich capabilities Could not require their customers to upgrade client or network infrastructure The Solution: Four Js BDL allowed Pentamation to predictably move 1000s of users to windows in less than one year SUNGARD/Pentamation It would have taken many years to rewrite our complete suite of applications and get them to market, and that would have equated to many millions of dollars in lost revenues. We managed the transition to Four J's in a physical year. Jack Stork, VP Customer Services Pentamation

  19. The Application: Police Records and Emergency Response The Business Need: Competitive requirement to support Windows and mobile devices Wanted cross platform capabilities Clients requesting other databases The Solution: Four Js BDL allowed Versaterm to provide support for multiple platforms, databases and client interfaces Versaterm What's great about Four J's is that their tools give us cross-platform database compatibility and allow us to provide our customers with a mixed environment. We can support Informix, Oracle, and other database environments, as well as text-based and GUI desktops, so we don't have to force clients to upgrade. Sue Langlois, Technical Configuration Manager Versaterm
