What recovery actions is required for ensuring the durability property of a database?
Durability is one of the ACID properties of computer science, which guarantees the reliable processing of database transactions (single logical operations). Specifically, durability ensures that committed transactions will persist even if the system crashes. This can be obtained via a transaction log or flushing the transaction's log records to non-volatile memory before returning an acknowledgement for the transaction.
What is recovery model?
SQL Server backup and restore operations occur within the context of the recovery model of the database. Recovery models are designed to control transaction log maintenance. A recovery model is a database property that controls how transactions are logged, whether the transaction log requires (and allows) backing up, and what kinds of restore operations are available. Three recovery models exist: simple, full, and bulk-logged. Typically, a database uses the full recovery model or simple recovery model. A database can be switched to another recovery model at any time.
What is the difference between olap and oltp?
Hi, The difference can be highlighted by defining the two entities separately, OLTP: Online Transaction Processing is a system normally used in the regular routine of database or User end Transactions (These Transactions are short Transactions). In OLTP, the data is fully normalized in order to avoid redundancy,Duplication of data etc, for achieving normalization various Joins are used that connects the tables. (without these joins OLTP cannot be fully Normalized). Now move on, OLAP: Online Analytical Processing is a system helpful for analysis purposes, it is used in Business Intelligence for analysis reporting, unlike OLTP it doesn't have too many joins in it because in OLAP it is not required to normalize the data, the basic purpose is to make Facts and Dimensions. <<Specifically for reporting purposes the data retrieval should be faster (The joins make the data processing slow) so the basic need of designing OLAP is to make the reporting system faster.>>
