BlockChain

 Blockchain Platform

- Ethereum
- Corda
- Multichain
- Quorum
- Hyperledger Fabric

Why blockchain - mainstream?

Cross border monetary payment system
- High transaction Fee
- Double Spending
- Internet fraud

Benefits

- Decreased Costs
- Reduced Fraudulent activity
- Increased Security

Blockchain is a distributed database of uneditable records called blocks, which are secured using cryptography

Blocks is a record book which contains the details of transaction data.

Elements of Block

- Hash
- Hash of previous block
- Nonce
- Transaction Data


Hash is an alphanumeric value which is used to identify a block.

Nonce is a random value which is used to vary the value of hash..

Payments transparent  and accountable

XML Publisher

Steps to create a XML Publisher Report   1] Add the “Xml Publisher Administrator” Responsibility to the user through the front end. 2] Create the Report(Data Model or we can say the .Rdf file) using Oracle Report Builder. 3] Set the user parameter as p_conc_request_id. 4] Add the default values to the Before Report and After Report triggers(not mandatory) 5] Ftp the Report to the Cust_Top/Report/Us. 6] Open the Oracle E-Business Suite then go to Sysadmin>Concurrent>Program>Executables, Here we have to create one executable file for that Rdf. 7] Then go to Sysadmin>Concurrent>Program>Define, Here we have to make a Concurrent Program for that Executable. Make sure that the output format must be XML. 8] Goto the Sysadmin>Security>Responsibility>Define. Query for the Xml Publisher Administrator. See the Request Group attached to this. Attach the Concurrent Program to this Request Group. 9] Design the template in Ms Word(Using the .Rtf file). 10] Goto responsi...
