Historization is the process of keeping track of data changes over time. We show how ACID transactions play a key role in Data Historization. In order to maintain consistency in a database, before and after the transaction, certain properties are followed. Concurrent writes follow an optimistic concurrency control protocol, with the first transaction to commit succeeding leading to a restart of all other conflicting concurrent transactions. Transactions access data using read and write operations. QUOTE: A transaction is a single logical unit of work which accesses and possibly modifies the contents of a database.According to Gray and Reuter, IMS supported ACID transactions as early as 1973 (although the term ACID came later). These four properties describe the major guarantees of the transaction paradigm, which has influenced many aspects of development in database systems. In 1983, Andreas Reuter and Theo Härder coined the acronym ACID as shorthand for atomicity, consistency, isolation, and durability, building on earlier work by Jim Gray who enumerated atomicity, consistency, and durability but left out Isolation when characterizing the transaction concept. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction. Implementing ACID transactions in a database requires significant systems engineering effort, especially when the database is distributed across multiple nodes. They help enterprises simultaneously gain customer data integrity and app development agility. ![]() In the context of databases, a sequence of database operations that satisfies the ACID properties (and these can be perceived as a single logical operation on the data) is called a transaction. ACID transactions are a fundamental feature of operational databases. ![]() In computer science, ACID ( atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee validity even in the event of errors, power failures, etc.See: Relational Database Management System.An Atomic Consistent Isolated Durable (ACID) Transaction is a data transaction that is an atomic transaction, a consistent transaction, an isolated transaction and a durable transaction. FairCom DB gives you a highly tunable database engine designed for mission critical transaction processing (OLTP) that guarantees ACID properties of your.
