Michael StutzInterfaces: The Next Generation
Integration Broker and Similar Tools
• Independent PeopleSoft Consultant• Started Technical• Do both Functional and Technical consulting• Primary Focus HCM and Campus Solutions• 25 years of IT industry experience• 16 years of PeopleSoft consulting experience• PeopleSoft v.2.11 – v.9.1• Lost Track of the number of PeopleSoft Projects I’ve been
on• Here at OHUG to network . . . • . . . and to share my insights on the future of interfaces in
the PeopleSoft environment
Agenda
• The Stage for Change• Term Demystification• What Change Looks Like• Integration Broker and Other Tools
Interfaces: The Next GenerationIntegration Broker and Similar Tools
History• 1925 – Smoke Signals• 1950 – The Telephone• 1975 – Greenbar (where most of our trees went)• 1985 – Magnetic Tape, followed by
Diskettes• 1995 – FTP• Today
The Stage is Set• PeopleSoft was designed from the ground
up as a transition for large enterprise computer systems:o from mainframe based o to Client / Server based systems
• Databases, although more advanced today, were, and still are where the vast majority of business data is stored
The Stage is Set• With Client / Server, business rules were
programmed into the online system and stored as Metadata . . .
• In our case, the Metadata is coding (PeopleCode) stored in the database instead of a program file:o Business rules defined & implemented on the
cliento Business rules defined & implemented on the
servero But ALL in the database as Metadatao . . . and ALL for the online portion of the system
• Which leads us to a big motivation . . . . . . business rules are duplicated in batch
programs . . . and so they also have to be maintained
separately
The Stage is Set• At the dawn of PeopleSoft, and still today,
the vast majority of Interfaces are executed using flat files on a batch basis
• For batch processing PeopleSoft doesn’t want us to mess with . . . they use COBOL
• For batch processing PeopleSoft knows clients will likely need to modify . . . they use and deliver SQRs:o Reportingo Interfaces
The Stage is Set
• Today . . . reports have been evolving:o PeopleSoft Queryo Crystal Reportso Business Intelligenceo Reporting Cubes
• But the interface evolution has only begun . . .
What Interface Change Looks Like
• Batch Mode of Interface . . . • Real Time Mode of Interface
o Non-human interventiono across the Internet . . .
• Removal of Business Rule Duplication• . . . with all of this, come a whole host of
technology and associated acronyms and terms
Hold onto your Seats . . .
• HTML• XML• WSDL• WSIL• UDDI• API
• Java• JMS• BEA• Tuxedo• Jolt• TCP/IP
Here Comes Demystification . . .
• HTTP• FTP• SMTP• SOAP• MIME• AJAX
HTML• Hypertext Markup Language• Uses “<“, “>”, “/”, and a few other characters
to designate code
<html><head></head><body>Hello World</body></html>
XML• Extensible Markup Language• Uses “<“, “>”, “/”, and a few other
characters to designate code, but continues on to be able to redefine itself.
XSD• XML Schema Definition• A way to describe and validate XML
data• Allows the same custom “tags” to be
read differently in different XML documents
WSDL• Web Services Definition Language• Common XML language specific to businesses
WSIL• Web Services Inspection Language• Common XML language used to inspect a site
for available services
UDDI / UBR• Universal Description, Discovery and
Integration• UDDI Business Registry• An internet directory where businesses
list themselves . . . and can discover each other
API• Application Program Interface• Prebuilt pieces of programs . . . used as
building blocks . . . to develop a program (or enhance another program) to interface with other systems
Java• The name of a software platform . . . • . . . a number of computer software products
and specifications from that together provide a system for developing application software and deploying it in a cross-platform environment
JMS• Java Message Server• A proprietary protocol & associated language
similar in function to HTTP and HTML, only more complex
Jolt• Java class library and API that provides an
interface to BEA Tuxedo from remote Java clients o The company's three founders: Bill Coleman, Ed Scott
and Alfred Chuango Transactions for Unix, Extended for Distributed
Operations
TCP/IP• Transmission Control Protocol• Internet Protocol• The first two networking protocols
defined• Today's IP networking represents a
synthesis of two developments that began in the 1970s, namely LANs (Local Area Networks) and the Internet, both of which have revolutionized computing. (www.wikipedia.org)
HTTP• Hypertext Transfer Protocol• Protocol for data transmission on the internet• Original purpose to provide a way to publish
and retrieve HTML pages. Development of HTTP was coordinated by the W3C (World Wide Web Consortium) and the IETF (Internet Engineering Task Force), culminating in the publication of a series of (RFCs) Request for Comments like RFC 2616 (1999), which defines HTTP/1.1, the version of HTTP in common use today. (www.wikipedia.org)
FTP / SFTP
• File Transfer Protocol• SSH File Transfer Protocol• A common misconception is that
SFTP is simply FTP run over SSH; in fact it is a new protocol designed from the ground up by the IETF SECSH working group. It is sometimes confused with Simple File Transfer Protocol. (www.wikipedia.org)
Email• Specific Format & Layout• Commonly Used• Allows for Attachments
SMTP• Send Mail Transfer Protocol
POP• Post Office Protocol
IMAP• Internet Message Access Protocol
MIME• Multipurpose Internet Mail Extensions• is an Internet Standard that extends the
format of e-mail to support:o text in character sets other than US-ASCII;o non-text attachments;o multi-part message bodies; ando header information in non-ASCII character sets.
(www.wikipedia.org)• Most e-mail is transmitted via SMTP in MIME
format• The content types defined by MIME standards
are also used in communication HTTP and other protocols
SOAP• Simple Object Access Protocol• A way of communicating between
programs on different operating systems using HTTP and XML
URL/URI
• Uniform Resource Locator• Uniform Resource Identifier
AJAX
• Asynchronus• Javascript
o and• XML
Time to wake up . . .
What Change Looks Like
• First we have Client / Server Architecture • Which came hand in hand with
o GUI Interfaceso Business Rules Stored as Metadata
• Followed by o Components, o Component Interfaces, and o Application Engine
What Change Looks Like
• Moving more and more toward reuse of online metadata Business Rules in a batch mode
• Evolving into greater use of batch mode “non-human” Component Interface integration with the outside world . . . using all the various current technology . . . with some of the newer PeopleSoft delivered tools . . .o Integration Brokero XML Publishero Workflow
