PERFORMANCE
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 HANA base administrators can master the database in a way that wasn't possible back then. The SAP database is much more self-healing. Errors do less damage, are easier to detect and fix, and are less likely to impact system performance and availability before they are fixed. Monitoring tools can automatically scan the application logs, identify potential errors, and even suggest fixes, making it much easier to get to the root of the problem.
Tasks and activities
In the database, which is located on a database server, all data of a company is saved. Application programs pull the data they need from the database. This data can consist of data tables, applications or system control tables. In addition, the database also takes new information from users and backs it up.
In the area of SAP Basis it is necessary to make temporary changes in the security settings of the clients and systems in the course of system updates. You can use the system changeability variable to specify whether changeability of cross-client data, such as programs or menus, as well as client-independent customizing is allowed.
Use "Shortcut for SAP Systems" to accomplish many tasks in the SAP basis more easily and quickly.
SAP Basis is the foundation of any SAP system. You can find a lot of useful information about it on this page: www.sap-corner.de.
Third-party application management tools such as Protera AppCare build on HANA's enhancements to provide SAP Basis administrators with better visibility and the ability to achieve better performance, faster time to value and cost savings.
