Error analysis and correction in the databases and the SAP system
In order to make a transaction in cryptocurrencies, you do not have to let your bank know about it as you would for "normal" money, but you have to use the Private Key to prove that you own the coins. The transaction looks like a piece of the puzzle. Half of the puzzle piece consists of information about the coin set, time and public address of the sender or receiver. The other half is the signature of the private key belonging to the sent public address. Both halves make this piece unique. Changing only one piece of information would completely change the whole transaction or the appearance of the puzzle piece. This transaction is transferred to the network or to the miner and is checked for correctness first. If everything fits, the transaction will be sent to other miners who will do the same. Otherwise, the transaction is ignored. Miners try to integrate the transactions into a block. This is called mining and we have described it so that the miners put the puzzle pieces together into a puzzle (block). A small part of a block to be integrated follows from the block that was previously mined. If all miners accept the correctness of a completed block, they will all work the next one immediately. The puzzle (block) is fixed and is irrevocably connected to the block before or after. The blocks form a chain and are called blockchain, which contains all the transactions that have ever been made and is visible and unchangeable by everyone. In doing so, blockchain replaces a central institution and avoids double-spending, which ultimately gives value to a cryptocurrency. Smart Contracts The biggest advance compared to Bitcoin and similar applications is that second-generation blockchains, such as Ethereum, use the so-called Turing-Complete script language Solidity. This enables calculations to be made within the blockchain. While Bitcoin allows only rudimentary multi-signature functions, Ethereum opens the door to much more complex operations called smart contracts. Smart contracts are contracts in which a decentralised blockchain ensures their unchangeability and execution.
SAP offers a huge toolbox of different technologies to support business processes. The usefulness of their use is essentially determined by the task and its technical requirements. We have gained a lot of valuable experience in the following technologies, which we would like to make available to you.
Automatic error handling when a job is aborted is desirable and useful in most cases. The conscious processing and consideration of error situations in job chains - also at step level - can help to reduce manual effort. Error situations should be catchable: If they are non-critical elements, the following job can perhaps be started anyway. In the case of critical errors, a new attempt should be made or an alert issued so that an administrator can intervene manually. Simple batch jobs are usually not capable of this. The goal of an automated environment is not to have to react manually to every faulty job.
Administrators often need to replicate part or all of a database, for example, to create a system backup or test an upgrade before putting it into production. In the past, this was surprisingly difficult to do with most databases. With HANA, replication works instantly and offers richer features and better control than previous databases.
Tools such as "Shortcut for SAP Systems" complement missing functions in the SAP basis area.
Data that the user enters in the SAP GUI is passed on to the database via the application servers.
SAP Basis operations manage the IT underlying the SAP system.
