As Promised in my Previous post [Video] : Oracle SOA Suite Development : Domain Value Map (DVM) to share Video on MDS (Metadata service) , we are here and exited to share 5 Min Tech clip Video on MDS (MetaData Services) for SOA Developers which is very hot topic in market and you Must have knowledge on MDS.
In this Video , we are going to look at what is Metadata service in Oracle SOA Suite, how to refer shared artifacts from MDS.
Oracle SOA MDS : Used to store Common Artifacts (xsd, wsdl,dvm etc:)
MDS is a Central Repository which is used to store shared Artifacts , deployed composites, configuration files.Those files which can be shared among multiple SOA Projects / Services are recommended to be stored in MDS. It is more commonly used to reduce the jar size and avoid redundancy of the code.
For More explanation refer the Video==>
Various types of File which can be stored in MDS as :
- XSD file
- WSDL file
- Fault Handling related files
- spring context
MDS can be of two types:
a) File based b) DB based
Below is the Slides of our Training where is have covered MDS in more detail :
Why Developers should use File Based MDS instead DB Based MDS :
File based MDS resides in local machine of developers and each developer has his/her own copy of file based MDS. It is replica of DB based MDS. This file based MDS is used during the development time .
The only reason why developers should use File based MDS is because at the time of development if we are using DB based MDS, it might take more time to access files as compared to file based MDS and can slow down the speed of development.
Note : SOA Server look up for the files from DB based MDS but Developers can use both File based MDS and DB based MDS .
This is only a teaser of our SOA Development Training if you want more depth details and want to see full picture , Register for this Course Oracle SOA Suite Development Training with Atul Kumar (Oracle ACE & Author) and Sumit K. (SOA Expert)
