there are two types of parameters we can create
1.Job level parameters. - Those parameters only use in that particular job.U can create in Desinger.
2.Project Level parameters. - Those parameters can use into multi jobs under that particular project.Using Admin we have to create the project level parameters.
Use - Dynamic value passing at runtime(while running of job) like file_name , path etc.so, runtime u can pass the file name or path or whatever u want.so ur job wil be dynamic take that parameters and do perform the work.
i hope u understand the parameters usage.

Parameters are helps to enter values at run time. and also makes secure by not to forcing a hard coding.
Unit testing is the one mainly deals with a single job.
system testing is the one deals with system compatabilty.
integration testing deals with entire set of jobs that meets business requirements.
Schudeling jobs helps to set a timer to run a job at a perticuler event of time
error hanling is done through a stage in job sequences.
We can remove duplicates using remove duplicate stage

The main purpose of job parameters in Datastage is to provide the values at job run time.Ex;File Path,File name,database server name,userid,password.
