JOB MANAGEMENT
In order to reduce the complexity of the SAP basis operation and to accelerate and simplify the tasks of the SAPBasis and to create free capacities, standardisation and automation of the existing activities is required. Details can be found in chapters 7.7 and 9.5 of the Master's thesis.
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.
IT Security
In order to demonstrate the necessary open spaces and capacities and also to demonstrate the innovative power of the SAP basis, regular reporting to the CIO or the management is recommended. If a product or technology is successfully evaluated, this can also be published as a success story within the framework of SAPBasis marketing (see chapter 7.4 in the Master's thesis) within the company.
It should be mentioned here that it only makes sense to access the tables by reading the SELECT statement to get a quick view of the results. Using the DBACOCKPIT, it is not possible to create entire table structures using Create Table. For such applications, SAP provides other, better options. Another important point is that once a user has the necessary permissions to use the transaction DBACOCKPIT, it can potentially (with appropriate permissions on the tables) access the entire SAP system. For example, a query can be used to read the entire user table. Therefore, the transaction should always be treated with caution and only awarded to administrators. DBACOCKPIT handles the call control permissions similar to the SE16 / SE16N transaction. When the table is called, the S_TABU_DIS or S_TABU_NAM permission object is checked with a specific activity. This means that only the tables or table permission groups for which the corresponding values in the aforementioned permission objects are assigned can be accessed. You can read more about assigning permissions to individual tables here. In addition, you can save SQL statements that you run once, and run them again at any time to recognise changes in the result set without having to reformulate the SQL statement each time. The editor also allows you to start the query for SQL statements in the background. The result is obtained by calling the transaction SM37, in which the result is output in a spool file.
Some missing SAP basic functions in the standard are supplied by the PC application "Shortcut for SAP Systems".
People tend to forget how important this element of the architecture is.
Only with professional care and maintenance of its components can SAP NetWeaver bring its advantages as an integrative platform to bear.
