Introduction to Hashing in DBMS Hashing in a Database Management System is a procedural approach applied to rationally find the position of the required data, instead of creating new indexes or using the existing index structures of the database system, by making use of dedicated methods called t...
Static Hashing in a Database Management System (DBMS) can be defined as a technique for mapping the finalized or unchangeable data of illogical sizes into ordered flat sizes in the database. It is achieved by applying the respective hashing functions, where the static hash values are also calle...
very large databases/ C6130 Data handling techniques C6160Z Other DBMS C6120 File organisationData mining techniques have attracted the attention of researchers from various areas. One of the most important issues in data mining is the mining of association rules from very large and frequently ...
Despite the prior art methods such as the ones suggested above, collisions still remain a major problem that affect performance. Both open and closed addressing tables are still affected, the latter being affected in terms of chain length. Many of the similar schemes also have other disadvantages...

It was added as a submodule and connected to ClickHouse build system, but we still couldn’t use its methods in C++ code. For that we needed to fix compatibility issues between Rust data types and C++ data types. The solution was simple: we wrote a shim function in Rust. It takes varia...
Returning string copies in substr-like functions results in absurd volume of allocations. Incremental construction via push_back-like functions goes through too many branches. Inconsistency between string and string_view methods, like the lack of remove_prefix and remove_suffix.Check...
in one node the nodes are coalesced. Keep track of the value in the parent between the pointers to the two nodes. Combine the two nodes into one. If the node is a leaf node re-connect the links between leaves. Delete (using this procedure) the value in the parent. If the values ...
Other conventional methods of searching for an object include use of hashing methods whereby an object, such as a rule, is hashed to an integer value which determines its identification and, sometimes, its uniqueness. Next, a search routine looks for the object in a database table or a ...
