Availability

In reliability theory and reliability engineering, the term availability has the following meanings.

Block Range Index

A Block Range Index or BRIN is a database indexing technique.

Column (database)

In a relational database, a column is a set of data values of a particular simple type, one value for each row of the database.

Consistent hashing

Consistent hashing is a special kind of hashing such that when a hash table is resized, only K/n keys need to be remapped on average, where K is the number of keys, and n is the number of slots.

Data striping

In computer data storage, data striping is the technique of segmenting logically sequential data, such as a file, so that consecutive segments are stored on different physical storage devices.

Database

A database is an organized collection of data, stored and accessed electronically.

New!!: Partition (database) and Database · See more »

Database index

A database index is a data structure that improves the speed of data retrieval operations on a database table at the cost of additional writes and storage space to maintain the index data structure.

New!!: Partition (database) and Database index · See more »

Database normalization

Database normalization is the process of restructuring a relational database in accordance with a series of so-called normal forms in order to reduce data redundancy and improve data integrity.

New!!: Partition (database) and Database normalization · See more »

Database transaction

A transaction symbolizes a unit of work performed within a database management system (or similar system) against a database, and treated in a coherent and reliable way independent of other transactions.

New!!: Partition (database) and Database transaction · See more »

Distributed database

A distributed database is a database in which storage devices are not all attached to a common processor.

New!!: Partition (database) and Distributed database · See more »

Load balancing (computing)

In computing, load balancing improves the distribution of workloads across multiple computing resources, such as computers, a computer cluster, network links, central processing units, or disk drives.

Nordic countries

The Nordic countries or the Nordics are a geographical and cultural region in Northern Europe and the North Atlantic, where they are most commonly known as Norden (literally "the North").

New!!: Partition (database) and Nordic countries · See more »

Program optimization

In computer science, program optimization or software optimization is the process of modifying a software system to make some aspect of it work more efficiently or use fewer resources.

New!!: Partition (database) and Program optimization · See more »

Relational database management system

A relational database management system (RDBMS) is a database management system (DBMS) based on the relational model invented by Edgar F. Codd at IBM's San Jose Research Laboratory.

New!!: Partition (database) and Relational database management system · See more »

Row (database)

In the context of a relational database, a row—also called a tuple—represents a single, implicitly structured data item in a table.

New!!: Partition (database) and Row (database) · See more »

Set operations (SQL)

Set operations allow the results of multiple queries to be combined into a single result set.

New!!: Partition (database) and Set operations (SQL) · See more »

Table (database)

A table is a collection of related data held in a structured format within a database.

New!!: Partition (database) and Table (database) · See more »

Transaction log

In the field of databases in computer science, a transaction log (also transaction journal, database log, binary log or audit trail) is a history of actions executed by a database management system used to guarantee ACID properties over crashes or hardware failures.

New!!: Partition (database) and Transaction log · See more »

View (SQL)

In a database, a view is the result set of a stored query on the data, which the database users can query just as they would in a persistent database collection object.

New!!: Partition (database) and View (SQL) · See more »

ZIP Code

ZIP Codes are a system of postal codes used by the United States Postal Service (USPS) since 1963.
