2. Database object - Wikipedia

   en.wikipedia.org/wiki/Database_object

   A database object is a structure for storing, managing and presenting application- or user-specific data in a database. Depending on the database management system (DBMS), many different types of database objects can exist. [1] [2] The following is a list of the most common types of database objects found in most relational databases (RDBMS):

3. Lists of database management systems - Wikipedia

   List of column-oriented DBMSes that store data tables by column rather than by row; List of in-memory databases, which primarily rely on main memory for computer data storage; See Category:Database management systems for a complete lists of articles about database management systems.

4. Temporal database - Wikipedia

   en.wikipedia.org/wiki/Temporal_database

   Non-relational, NoSQL database management systems that provide temporal features including the following: TerminusDB is a fully featured open source graph database that natively supports version control, time-travel queries and diffing functions. It has an immutable layer architecture based on delta encoding and succinct data structures. [16]

   A database management system (DBMS) is a computer program (or more typically, a suite of them) designed to manage a database, a large set of structured data, and run operations on the data requested by numerous users. Typical examples of DBMS use include accounting, human resources and customer support systems.

6. Isolation (database systems) - Wikipedia

   en.wikipedia.org/wiki/Isolation_(database_systems)

   Isolation is typically enforced at the database level. However, various client-side systems can also be used. It can be controlled in application frameworks or runtime containers such as J2EE Entity Beans [2] On older systems, it may be implemented systemically (by the application developers), for example through the use of temporary tables.

7. Database storage structures - Wikipedia

   Heap files are lists of unordered records of variable size. Although sharing a similar name, heap files are widely different from in-memory heaps. In-memory heaps are ordered, as opposed to heap files. Simplest and most basic method insert efficient, with new records added at the end of the file, providing chronological order

8. Tombstone (data store) - Wikipedia

   en.wikipedia.org/wiki/Tombstone_(data_store)

   A tombstone is a deleted record in a replica of a distributed data store. [1] The tombstone is necessary, as distributed data stores use eventual consistency , where only a subset of nodes where the data is stored must respond before an operation is considered to be successful.

9. Durability (database systems) - Wikipedia

   en.wikipedia.org/wiki/Durability_(database_systems)

   Existing database systems use volatile storage (i.e. the main memory of the system) for different purposes: some store their whole state and data in it, even without any durability guarantee; others keep the state and the data, or part of them, in memory, but also use the non-volatile storage for data; other systems only keep the state in main ...
