海外TECH	DEV Community	Databases: Important Theoretical Concepts	https://dev.to/fahidlatheef/databases-important-theoretical-concepts-4nll	Databases Important Theoretical Concepts IntroductionIn the previous episode I discussed the important SQL Statements Keywords that are useful for day to day SQL use In today s episode I will try to explain few important Database Concepts that will boost our understanding even further TransactionsTransaction is a fundamental concept of all database systems It bundles multiple steps into a single all or nothing operation The intermediate states between the steps are not visible to other concurrent transactions and if some failure occurs that prevents the transaction from completing then none of the steps affects the database at all Transactions can be further tuned by BEGIN COMMIT and ROLLBACK operations BEGINEach transaction is explicitly initiated using BEGIN TRAN COMMITBy using COMMIT TRAN a transaction is closed explicitly and modifications performed by the transaction are made permanent ROLLBACKBy using ROLLBACK TRAN a transaction is explicitly closed and any modifications made by the transaction is discarded Each Transaction should follow ACID rules ACIDACID stands for Atomicity Consistency Isolation and Durability This describes a set of properties that apply to data transactions For a reliable database all these four attributes should be achieved AtomicityAtomicity is also known as the All or nothing rule It means that either the entire transaction takes place at once or doesn t happen at all There aren t any partial transactions Hence it is known as the All or nothing rule ConsistencyIt says that the database should be consistent before and after the transaction Data types triggers constraints etc It refers to the correctness of a database IsolationThis property says that the transactions occur independently without interference This property ensures that the execution of transactions concurrently will result in a state that is equivalent to a state achieved these were executed serially in some order DurabilityIt says that once the transaction is saved or committed it can t be “lost Data won t go missing after a power outage or system crash LOCKING MECHANISMLocking is designed to allow SQL Server to work seamlessly in a multi user environment Locking is the way that SQL Server manages transaction concurrency While objects are locked SQL Server will prevent other transactions from making any change of data stored in objects affected by the imposed lock Once the lock is released by committing the changes or by rolling back changes to the initial state other transactions will be allowed to make required data changes CAP THEOREMCAP Theorem aka Eric Brewer Theorem states that we cannot build a general data store that is continually available sequentially consistent and tolerant to any partition failures We can only achieve features out of these ​A combination of must be chosen and this is usually the deciding factor in what technology is used Consistency All the servers in the system will have the same data so users will get the same copy regardless of which server answers their request Availability The system will always respond to a request even if it s not the latest data or consistent across the system or just a message saying the system isn t working Partition Tolerance The system continues to operate as a whole even if individual servers fail or can t be reached TRIGGERSTrigger A trigger is a stored procedure in a database that automatically invokes whenever a special event in the database occurs For example a trigger can be invoked when a row is inserted into a specified table or when certain table columns are being updated Triggers can be run BEFORE or AFTER the triggering statement SQL NORMALIZATIONIt is the process of structuring a database following a series of Normal Forms to reduce data redundancy and improve data integrity Without Normalization in SQL we may face many issues such as Insertion anomaly It occurs when we cannot insert data to the table without the presence of another attribute Update anomaly It is a data inconsistency that results from data redundancy and a partial update of data Deletion Anomaly It occurs when certain attributes are lost because of the deletion of other attributes Some examples of Normal Forms are NF NF NF BCNF etc DATABASE ISOLATION LEVELSDatabase Isolation levels control the degree of locking that occurs when selecting data This is to prevent reads and writes of temporary aborted or otherwise incorrect data written by concurrent transactions For many database applications the majority of database transactions can be constructed using isolation level priority rules reducing the locking overhead for the system These are the priority rules for isolation levels SerializableRepeatable readsRead committedRead uncommitted ReferencesTransactionsACID Resource ACID
