A Preliminary Study on MDS in oaf Development)

Recently, someone asked me what is MDS. To tell the truth, I didn't care much about it. I only knew it was called "metadata repository" (meta. data Services), today I took some time to study it. With some research results, I posted it to share it, ^ _ ^.

First of all, my starting point is to study the imported command. The BAT file I run in the Windows operating system is in D: \ p00009325_r12_generic \ jdevbin \ oaext \ bin directory, find export. bat, import. bat, jpximport. bat, xliffimport. BAT, the others did not look at it today, and I will try again later.

After studying import. bat, there are a bunch of verifications in front, and the final useful ones are Java oracle. jrad. Tools. xml. Importer. xmlimporter % Params %.

I am too lazy to find it locally. I directly log on to the application environment, and then CD $ java_top/Oracle, compress all classes in the jrad subdirectory into a tar package, download it, and open it with jdecompiler.

Oracle. jrad. Tools. xml. Importer. xmlimporter. Class

See, after some javaCodeThe following background objects are finally pointed:

---- Table
Applsys. jdr_attributes -- stores the attribute of the oaf component
Applsys. jdr_attributes_trans
Applsys. jdr_components -- store the oaf component tree
Applsys. jdr_paths -- store the oaf page path (directory tree)
---- Scripts
Jdr_mds_internal
Jdr_utils
Jdr_custom_internal
Jdr_docbuilder

The specific relationship has not been carefully read yet, but it is critical to find the jdr_mds_internal package. If you are interested, you can check it yourself.
