BEST MODE FOR CARRYING OUT THE INVENTION
Many of the functional units described in this specification have been labeled as modules, in order to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom VLSI circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices or the like.
Modules may also be implemented in software for execution by various types of processors. An identified module or component of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions which may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different locations which, when joined logically together, comprise the module and achieve the stated purpose for the module.
Further, a module of executable code could be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be identified and illustrated herein within modules, and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, over disparate memory devices, and may exist, at least partially, merely as electronic signals on a system or network.
Furthermore, modules may also be implemented as a combination of software and one or more hardware devices. For instance, a module may be embodied in the combination of a software executable code stored on a memory device. In a further example, a module may be the combination of a processor that operates on a set of operational data. Still further, a module may be implemented in the combination of an electronic signal communicated via transmission circuitry.

Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.
Moreover, the described features, structures, or characteristics of the invention may be combined in any suitable manner in one or more embodiments.

Reference will now be made in detail to the preferred embodiments of the invention.
In one embodiment, the invention provides a method for transforming a source code written in a source programming language into one or more target modules written in one or more target programming languages. The method comprises parsing a source code written in a source programming language. In an embodiment, the source code has one or more source modules. The method further comprises selecting one or more target programming languages suitable for transforming the one or more source modules of the source code into one or more target modules, looking up for a source function in the source code an equivalent target function in a target programming language of the one or more target programming languages selected, such that execution of the equivalent target function in the target programming language is optimized. The method further comprises writing out in the target programming language of the one or more target programming languages selected the equivalent target function corresponding to the source function, such that each of the one or more source modules of the source code is transformed into the one or more target modules whose execution in the one or more target programming languages is optimized. The method further comprises launching execution of each of the one or more target modules in the one or more target programming languages. In an embodiment, the parsing step further comprises reading each line of the source code written in the source programming language, and parsing each line of the source code into the one or more source functions. In an embodiment, the looking up step further comprises providing a target conversion table for transforming each of the one or more source functions of the source code into one or more target functions written in the one or more target programming languages selected. Further, the looking up step comprises looking up the source function of the source code in the target conversion table in order to transform the source function of the source code into the equivalent target function. In an embodiment, the writing step further comprises writing out the one or more target modules in the one or more target programming languages. In an embodiment, the source programming language is different than each of the one or more target programming languages selected.
Reference is now made to FIG. 1, which outlines the method steps involved in transforming a single source code into a plurality of target modules in one or more target programming languages, in accordance with an embodiment of the invention. Turning to FIG. 1, reference numeral 100, outlines the steps involved in transforming a single source code into a plurality of target modules in one or more target programming languages. The method starts in step 102 with starting execution of the transformation code for transforming a single language source program or code. In step 104, the transformation code reads or gathers configuration data stored in a configuration file 103 in order to transform the source program. In particular, the configuration file 103 provides input data, such as, which programming language to use for the source code and which target programming languages to use for transforming the source code into one or more target modules. For instance, the source code may be written in the Rexx programming language whereas, the target programming languages that the source code is to be transformed into may be a program module using the C programming language and another program module using the DB2 SQL programming language. The configuration file 103 also provides platform information for the target programming languages. For instance, the platform for the C program module may be an AIX platform, whereas, the platform for the SQL program module may be a UNIX or mainframe platform. Further, the configuration file 103 also provides location information for the source code, the location information where the target modules or programs will be stored as well as the location information for the function conversion table that is to be used for converting a function in the source code into an equivalent target function in a target programming language, such that execution of the target function in the target programming language is optimized. Further, in step 106, the transformation code reads a first source program, for instance, source program 105A of the source code stored in a storage system, such as, a database system. The transformation code parses the source program 105A. In particular, the source program includes one or more source modules. As such, the transformation code parses each line of a source module of the source program into one or more source functions. The transformation code locates or looks up in step 110 an ideal or equivalent target function from an inventory of functions, often referred to herein as a function conversion table or conversion table 109, which contains an inventory of all source functions in a source code or program in a given programming language. The function conversion table 109 provides an ideal or equivalent target function in a target programming language that corresponds to the source function, and whose execution in the programming language will be optimized. The transformation code locates or looks up in step 110 an equivalent target function for each of the source functions parsed in step 108. After the transformation code has located an equivalent target function for each source function in each of the source modules of the source program 105A, the transformation code writes in step 112 the equivalent target function in a target programming language that will provide optimized execution of the target function. The transformation code converts or transforms each source function by writing out an equivalent or ideal target function in a target programming language in which execution of the target function will be optimized. The transformation code will determine the optimal target function/code for a given source function based on the setting in the configuration file and based on the available inventory of target functions. For instance, if the configuration file 103 sets forth that the source code or program is to be transformed using three different programming languages, then a source function may be written as a target function in any one of three target programming languages, such as, programming language 1, reference numeral 114 or in programming language 2, reference numeral 116 or programming language 3, reference numeral 118, depending on which programming language will provide optimized execution of the target function transformed from the source function. As such, each source module in the source program 105A written in a single source programming language may be transformed into one or more target modules written in each of the three programming languages 114, 116 and 118 or in one programming language or even two programming languages chosen from the set of three programming languages 114, 116 or 118. Once the transformation code has transformed and written out the target functions corresponding to the source functions in the source program 105A, the transformation code reads the next source program, namely, source program 105B. The steps 108 through 112 are repeated as described herein above. Similarly, if there are more source programs to be transformed, then the transformation code reads the next source program, for instance, source program 105C and repeats steps 108 through 112 until all the source programs have been transformed.
Accordingly, as mentioned herein above a source program may consist of one or more source modules. In an embodiment, each source module gets transformed into one or more target modules. As each line of the source module is read, it is parsed into one or more source functions. Then based on the configuration data, each source function is transformed into a target function by doing a lookup in the inventory of functions. The transformation code will then select a replacement target function in a target programming language from the inventory of functions to be used based on the configuration data. The inventory of functions is a list or table of source to target mappings based on the source programming language and the target programming languages to be used. The transformation code then writes out one or more target modules in one or more target programming languages. In a simple case, if the source program is written in SAS and the target programming language to be used is C, for each supported SAS function, there would be an entry in the inventory with the corresponding C function. For example, if the SAS function is Foo=SUM(a,b) then the transformed version in C may be Foo=a+b. Similarly, if the selection as set forth in the configuration file is to transform a source program written in SAS into target modules written in C and DB2 SQL, then each source function is converted based on the priority of the function in the inventory table. For instance, functions that are more efficient in SQL, would be transformed into SQL and other functions that are more efficient in C would be transformed into C. In an embodiment, the target modules would typically stay together with the functions being called for one or more target programming languages. The master or main programming language selected would allow functions to run in other languages. For example, the main program might be C, with calls to SQL and PMML that are driven into the database.
Another example is of a source code written in the SAS programming language that is to be converted into the DB2 SQL programming language and the C programming language. For example, the SAS programming language has a function named MAX that fetches the largest number in a given set of numeric variables, for instance, VAR1, VAR2, VAR3. The SAS code for this function may be:

“MAX_VAR=MAX(VAR1, VAR2, VAR3);”

then the SAS source function would be looked up in the inventory of functions or the function conversion table depending on the configuration data obtained from the configuration file and converted into the DB2 SQL function:
















“CASE WHEN VAR1 > (CASE WHEN VAR2 > VAR3



    THEN VAR2



    ELSE VAR3



   END)



 THEN VAR1



 ELSE (CASE WHEN VAR2 > VAR3



    THEN VAR2



    ELSE VAR3



  END)



END AS MAX_VAR;”.










Further, the SAS source function MAX would be looked up in the inventory of functions or function conversion table, again, using the configuration data in the configuration file and converted into the C function:

“MAX_VAR=MAX(VAR1, MAX(VAR2, VAR3));”.

In another embodiment, the invention provides a system for transforming a source program written in a source programming language into one or more target modules written in one or more target programming languages. The system includes a source program written in a single source programming language, the source program having one or more source modules.

Referring now to FIG. 3, there is illustrated a system 300 for transforming a single source program in a source programming language into one or more target modules in one or more target programming languages, in accordance with an embodiment of the present invention. As depicted, system 300 includes a computer infrastructure 302, which is intended to represent any type of computer architecture that is maintained in a secure environment (i.e., for which access control is enforced). As shown, infrastructure 302 includes a computer system 304 that typically represents a server 304 or the like configured to transform a single source program in a source programming language into one or more target modules in one or more target programming languages that is accessed by a user or programmer at a client (e.g., a personal computer, a laptop, a handheld device, etc), for instance, user A 330. It should be understood, however, that although not shown, other hardware and software components (e.g., additional computer systems, routers, firewalls, etc.) could be included in infrastructure 302.
In general, a programmer or user (for instance, user 1, reference numeral 330) at a client is connected via a network to infrastructure 302, which includes a transformation code or component 316 that is configured to transform a single source program in a source programming language into one or more target modules in one or more target programming languages. Similarly, one or more users, such as user 2, reference numeral 332 and/or user 3, reference numeral 340 and/or user 4, reference numeral 342 can interface with infrastructure 302, which is configured to transform a single source program in a source programming language into one or more target modules in one or more target programming languages. To this extent, infrastructure 302 provides a secure environment. In particular, a user or programmer accesses the server or system 304 over a network via interfaces (e.g., web browsers) loaded on the client, for example, a personal computer, a laptop, a handheld device, etc. In the case of the latter, the network can be any type of network such as the Internet, a local area network (LAN), a wide area network (WAN), a virtual private network (VPN), etc. In any event, communication with infrastructure 302 could occur via a direct hardwired connection (e.g., serial port), or via an addressable connection that may utilize any combination of wireline and/or wireless transmission methods. Moreover, conventional network connectivity, such as Token Ring, Ethernet, WiFi or other conventional communications standards could be used. Still yet, connectivity could be provided by conventional TCP/IP sockets-based protocol. In this instance, the parties could utilize an Internet service provider to establish connectivity to infrastructure 302. It should be understood that under the present invention, infrastructure 302 could be owned and/or operated by a party such as provider 344, or by an independent entity. Regardless, use of infrastructure 302 and the teachings described herein could be offered to the parties on a subscription or fee-basis. In either scenario, an administrator 334 could support and configure infrastructure 302.
The server 304 is shown to include a CPU (hereinafter “processing unit 306 ”), a memory 312, a bus 310, and input/output (I/O) interfaces 308. Further, the server 304 is shown in communication with external I/O devices/resources 324 and storage system 322. In general, processing unit 306 executes computer program code, such as the transformation code or component 316, which reads in a source program that a user wants to transform.
