Figure 2: The Open Innovation Model
Before SAP HANA was released, there was no SAP database - you had to install SAP ERP (or the application you were using) on a third-party database, such as Oracle or SQL Server. SAP developed the HANA database to fully leverage the power of SAP's next-generation S/4 software.
How does a blockchain build consensus? Once you decide to send a payment to someone, you must use the Private Key to "sign" it (in German: signature). This means nothing other than that you specify another public address to which you want to send the money and confirm this transaction with your own private key. You don't have a central authority to send the information to, you're going to spread the information to all the other Miners around you. The miners then forward this information to other miners, who in turn do the same. This exponential wave of information reaches the entire network of the distributed community within a few milliseconds. Every time a miner receives a transaction, it checks that the transaction is actually correct. It checks which private key has signed, which public address the transaction should go to and whether the sender has enough "coins" for this transaction. What are consensus mechanisms? Any miner that solves a transaction through complex mathematical calculations is rewarded by the sender with a "fee" (transaction fee). How will it be decided which miner will receive the transaction fee? Because only one can get this reward. Also, what happens when you try a double spending by sending one transaction to one miner and then another transaction with the same money to another one millisecond later? These two could not yet exchange and thus information would be different in the network.
Introduction/training of the in-memory database
Each SAP Basis system must be controlled and managed by an administrator. This person is responsible for the smooth operation of the system. This can be an internal administrator or it can be handed over to external service providers.
By establishing a new role concept and building new roles, the SAP basis has the skills necessary to support new tasks and topics as well as to operate new technology and service forms. The relevant roles are listed below.
"Shortcut for SAP Systems" simplifies tasks in the area of the SAP basis and complements missing functions of the standard.
Therefore, these properties do not need to be maintained several times.
In case of non-compliance, for example due to project influences or technological problems, the exception must be returned to the standard in a timely manner.
