  2. Partition (database) - Wikipedia

    en.wikipedia.org/wiki/Partition_(database)

    Consistent hashing could be considered a composite of hash and list partitioning where the hash reduces the key space to a size that can be listed. Round-robin partitioning: the simplest strategy, it ensures uniform data distribution. With n partitions, the ith tuple in insertion order is assigned to partition (i mod n). This strategy enables ...

  3. Uniface (programming language) - Wikipedia

    en.wikipedia.org/wiki/Uniface_(programming_language)

    DBMS connectors map and convert Uniface data types to the most suitable format of the particular storage medium. At runtime, it is possible to pass parameters to invoke (or disable) database-specific extensions. Provided the database connector is licensed, it is possible to convert between different data sources.

  4. Oracle Database - Wikipedia

    en.wikipedia.org/wiki/Oracle_Database

    Oracle Database (commonly referred to as Oracle DBMS, Oracle Autonomous Database, or simply as Oracle) is a proprietary multi-model [4] database management system produced and marketed by Oracle Corporation. It is a database commonly used for running online transaction processing (OLTP), data warehousing (DW) and mixed (OLTP & DW) database ...

  5. Greedy number partitioning - Wikipedia

    en.wikipedia.org/wiki/Greedy_number_partitioning

    In computer science, greedy number partitioning is a class of greedy algorithms for multiway number partitioning. The input to the algorithm is a set S of numbers, and a parameter k. The required output is a partition of S into k subsets, such that the sums in the subsets are as nearly equal as possible. Greedy algorithms process the numbers ...

  6. Shard (database architecture) - Wikipedia

    en.wikipedia.org/wiki/Shard_(database_architecture)

    Horizontal partitioning splits one or more tables by row, usually within a single instance of a schema and a database server. It may offer an advantage by reducing index size (and thus search effort) provided that there is some obvious, robust, implicit way to identify in which partition a particular row will be found, without first needing to search the index, e.g., the classic example of the ...

  7. B+ tree - Wikipedia

    en.wikipedia.org/wiki/B+_tree

    B+ tree is efficiently used to construct an indexed search method called iDistance. iDistance searches for k nearest neighbors (kNN) in high-dimension metric spaces. The data in those high-dimension spaces is divided based on space or partition strategies, and each partition has an index value that is close with the respect to the partition.

  8. 3-partition problem - Wikipedia

    en.wikipedia.org/wiki/3-partition_problem

    The 4-partition problem is a variant in which S contains n = 4 m integers, the sum of all integers is ⁠ ⁠, and the goal is to partition it into m quadruplets, all with a sum of T. It can be assumed that each integer is strictly between T /5 and T /3.

  9. Comparison of relational database management systems - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_relational...

    Oracle has its own spin where creating a user is synonymous with creating a schema. Thus a database administrator can create a user called PROJECT and then create a table PROJECT.TABLE. Users can exist without schema objects, but an object is always associated with an owner (though that owner may not have privileges to connect to the database).
