Enterprise Application Integration

Sometimes you simply want two programs on one computer to work together, without a person spending 30 minutes each and every time you alter some trivial information. Maybe its extracting the monthly sales figures from twenty field reports, putting them into a Word document and then distributing this to 10 members of the board - some in the company, some outside it. Or perhaps its just re-keying a supplier's electronic catalogue into your computer system to assist others with their purchase orders. Maybe you'd just like to receive an SMS message on your mobile phone anytime the CEO sends you an email message or the main web server goes offline. Application to Application program (A2A) is about improving operations between different programs in an automated, easy process generally on a single machine. This goes beyond simple cut-and-paste to complicated object processing languages.
Scripting EnginesIn many cases, a scripting languages may be available for working with the language. These lightweight programs are evaluated each time they run, making it easy to make changes and implement them. This may include features like Visual Basic for Applications as found in the Microsoft Office Suite of programs. Or it may involve platform based scripting engines like javascript, vbscript, python and perl. Again, the code is compiled and executed each time the script is selected, makeing changes easy to implement.
Server processingIn some cases applications may be linked through web servers with background processing that can move data from system to system. This user-controlled activity provides sophisticated processing with a reactive environment. |
