DBMS offers automated procedures such as transaction log backups or point-in-time recovery for backup and recovery. You can customize these features according to your requirements to run regularly or at a specific time. This ensures a recent copy of the database is always available in case of ...
1.3.1.12Use of Type Inheritance Type inheritance enables you to create type hierarchies. A type hierarchy is a set of successive levels of increasingly specialized subtypes that derive from a common ancestor object type, which is called a supertype. Derived subtypes inherit the features of the pare...
The DBMS features can vary greatly. DBMS makes use of system commands to carry out these functions. It first receives instructions from a database administrator, and then the instructions are sent to the system to retrieve, modify, or load data....
In this article, we have discussed about the surrogate key in DBMS. The adoption of surrogate key in DBMS stands as a strategic choice, providing a range of benefits for efficient and reliable data management. The unique, stable, and meaningless nature of surrogate keys enhances data integrity,...

What are the features of a key-value database? A key-value database is defined by the fact that it allows programs or users of programs to retrieve data by keys, which are essentially names, or identifiers, that point to some stored value. Because key-value databases are defined so simpl...
Introduction of surrogate keys is based on the conservation of space as well as faster access. It is investigated as a solution for the cases where propagated key strings are too long or violate implementation DBMS limitations. In those cases where it is deemed viable, a surrogate key is creat...
However, the minute you introduce a second one, you have lost the property of uniqueness. We therefore forbid the presence of nulls in any primary key columns. This constraint, known as entity integrity, will be enforced by a DBMS whenever data are entered or modified. Identification of ...
The features of a key-value database The key-value store is one of the least complex types of NoSQL databases, which makes the model attractive to users that need to quickly sift through large volumes of basic information. It uses very simple functions to store, get and remove data. ...
