What's the difference between inTERnet and inTRAnet?

inTERnet refers to the world wide web (www) - a vast interconnection of computers that allows communication in virtually all directions and is accessible to just about anyone (although some sites require a form of membership in order to gain access).

inTRAnet refers to a private network owned by a company and allows access to only their employees and/or only those that are granted a login id and password. This is not a "membership" that you can buy into or sign up for; you are either elgible for access or not. Often a company will grant limited access of their intranet to their trading partners. Intranets allow employees within a company to exchange and share data that aids them in completing their tasks or provides company information such as employee benefits. Generally, the information found on an intranet is not of interest to the general public.

Below are some mainframe projects that I've worked on.

   Created mainframe screens to automatically compare information on a customer purchase order to the corresponding in-house production orders. Users are presented with a list of differences and may select the ones that they want to apply to the production order. When selected, the user is transferred to the appropriate screen with the new data filled in. All the user has to do is press Enter and verify the changes (the order entry system is highly integrated and changes to one piece of data often causes automatic changes, or suggestions for changes, to other pieces of data). This functionality has proven to be vital to users who used to find it quite a challenge to keep up with customer changes to orders.
   Implemented numerous enhancements to order entry, costing, and style definition applications on the mainframe using ADSO and COBOL.
   Implemented UPC processing such that whenever colors or sizes are added or changed on a garment, the corresponding UPC data is generated or modified. UPC data is sent via EDI to an online catalog, allowing customers to place orders electronically.

UPC modifications were implemented using ADSO and COBOL.
   Enhanced an EDI process to streamline receiving of orders from customers in standard EDI format and uploading them to the mainframe. Involved converting current DOS Gentran system to Windows Gentran system, enhancing COBOL programs that post data to the mainframe, and writing new ADSO programs to provide easy access to the data by users.
   Coded programs (COBOL and ADSO) to automatically send purchase orders via Gentran to various factories, and to automatically receive confirmations of receipt, and to make the status of transmission for individual orders accessible to users via mainframe screens.
   Performed analysis, coding, and testing to ensure that mainframe systems are year 2000 compliant. Involved updating JCL, COBOL, CULPRIT, and ADSO programs.
   Performed analysis and coding of enhancements to manufacturing and financial systems in a COBOL/ADSO/IDMS environment.
   Performed analysis and coding of enhancements to a financial system in a COBOL/ADSO/ IDMS/CULPRIT environment. Implemented EDI programs that automate receiving vendor invoices, verifying invoice data, and generating vendor checks.
   Performed analysis and coding necessary to convert data from several existing systems (written in CICS/ADSO/IDMS) to a format that would be compatible with an integrated software package (INDUS) that handles financial, purchasing, inventory, and bill of material applications.

Conversion involved writing programs using Easytrieve to analyze and convert current data; and reading through the new package's DB2/SQL source code to understand what the new system was expecting and how it worked.
   Performed analysis and coding of key components for a new integrated order entry system that involved extensive use of pop-up windows and a complex ADSA structure in an ADSO/IDMS environment. Resolved many problems inherent in forcing ADSO to work like a windowing environment.
   Performed analysis, spec writing, and coding of programs for a new customer information revenue system. Coded batch programs in COBOL II, accessing an IDMS database. Coded online programs using ADSO, and implemented new program interfaces via ADSA.
   Responsible for implementing changes to suspension and licensing systems in order to accommodate the new ALS (Administrative License Suspension) law.

Analyzed the business process and coded programs to correctly calculate suspension end dates while taking into consideration special rules such as consecutive vs. concurrent suspensions.

Coded modifications to records, subschemas, and online programs in ADSO; coded batch programs using COBOL.
   Performed analysis, spec writing, spec walk-thrus, and programming in order to implement changes that would allow a company to keep track of their private label insurance business.

This involved accessing shared and segmented IDMS databases, and heavy use of scratch records and ADSA "flows" (default responses).

Modified ADSO dialogs, COBOL batch programs, PJCL, procs, and DYL280 programs. Worked with MVS, TSO/ISPF, SDSF, DBOL, GENX, ADS Alive, and XD (Express Delivery).
   Performed analysis and coding needed to develop a new system to automate the capturing and electronic generation of titles (e.g. vehicle titles). All work was done in COBOL and ADSO, accessing an IDMS database.
   Designed and coded programs in ADSO/COBOL/IDMS for sales and inventory applications.

Coded programs to handle conversion from in-house/Axis software running on the Prime computer to CAS (Cullinet Application System) software running on the IBM.

Trained users when new features of the system were implemented.
   Designed and coded manufacturing programs in COBOL.

Troubleshot user problems on NCR; resolved mainframe software and hardware problems; incorporated custom changes into new releases of IMCS II, an interactive manufacturing control system.
