Michael picked up on my workflow post and added some great points regarding messaging<\/a>. <\/span>I thought I\u2019d do a light \u201cprimer on messaging\u201d to round out the topic. <\/span>Now I have to figure out how to explain this in 3 paragraphs.<\/p>\n

Michael hits on the old CORBA model and compares it to XML. <\/span>CORBA is simply a standard for object request brokers and there are other similar standards for ORBs as well. <\/span>XML is a simple markup language that allows a simpler interface of data between data repositories. <\/span>I\u2019ll get back to this later, but let me first simplify and make our discussion a bit more generic.<\/p>\n

When we talk about the \u201cold\u201d model of data interfaces, we\u2019re really talking about \u201casynchronous\u201d messaging. <\/span>Async messaging really just means that someone has to push a data file out and the receiving database needs to actively receive it. <\/span>So the good old days when you \u201ccreated\u201d the interface file (usually a push of a button somewhere) and the file would then upload to an FTP server or whatever. <\/span>The receiving end then goes to that FTP server and loads the data into the receiving database. <\/span>One simple advance in async messaging was the simple ability to schedule these push pull processes so that a human no longer needed to be around to kick off the process. <\/span>Even then, it\u2019s still async messaging. <\/span>Why? <\/span>Because it\u2019s not real time. <\/span>You can new hire a person into the database, but that person is not getting loaded to your medical insurer\u2019s database until the interface file runs 3 hours later.<\/p>\n

When we talk about the \u201cnew\u201d model, we are talking real time, or synchronous messaging. <\/span>This is what the HR-XML Consortium<\/a> is all about. <\/span>An example of this is you indicate that your applicant is now a new hire, the ATS sends a message instantly to your HRMS with employee data and status changes, your HRMS instantly sends data to your medical insurance provider with enrollments. Sounds cool, right?<\/p>\n

The key to synchronous messaging is standardization. <\/span>Old async models were a pain because every interface had to be programmed individually, and every time you upgraded one of the software applications, you had to rewrite the interface. <\/span>In a sync model (like XML), you don\u2019t really care about the interface file and how it\u2019s formatted. <\/span>Instead, the HR-XML consortium tells you what the format is supposed to be, you markup your file appropriately, and every sender and receiver of these files is supposed to be on board.<\/p>\n

Up next, a primer on HRMS evolution and how messaging is the key behind this year\u2019s advancements.<\/p>\n
