Referral Whois (RWhois) is an extension of the original WHOIS protocol and service. RWhois extends the concepts of WHOIS in a scalable, hierarchical fashion, potentially creating a system with a tree-like architecture. Queries are deterministically routed to servers based on hierarchical labels, reducing a query to the primary repository of ...
Query rewriting is a typically automatic transformation that takes a set of database tables, views, and/or queries, usually indices, often gathered data and query statistics, and other metadata, and yields a set of different queries, which produce the same results but execute with better performance (for example, faster, or with lower memory use). [1]
The Shared Whois Project (SWIP) is the process used to submit, maintain and update information to ensure up-to-date and efficient maintenance of WHOIS records, as structured in RFC 1491. [1]
RDAP databases for assigned IP numbers are maintained by five Regional Internet registries. ARIN maintains a bootstrap database. [9] Thanks to the standard document format, tasks such as, for example, getting the abuse team address of a given IP number can be accomplished in a fully automated manner.
A graph database consists of a directed graph whose edges carry a label. A regular path query is just a regular expression over the set of labels. For instance, in a graph database where vertices represent users and there is an edge label "parent" for edges from a parent to a child, the regular path query would select pairs of a node x and a descendant y of x, with a path from x to y of ...
Views take very little space to store; the database contains only the definition of a view, not a copy of all the data that it presents. Views structure data in a way that classes of users find natural and intuitive. [2] Just as a function (in programming) can provide abstraction, so can a database view. In another parallel with functions ...
If you need to make changes to a number of articles based on a particular query, you can post to the bot requests page, depending on how many changes are needed. For long-term review and checking, database reports are available. Quarry does not have access to page content, so queries which require checking wikitext cannot be answered with Quarry.
The pWhoIsd server software responds to standard whois queries and supports a variety of output formats (including Prefix WhoIs native, Cymru, and RPSL).; The pWhoIs-updatedb agent parses routing information bases (RIBs) from Internet routers or digests from route-views servers in text or MRT format and populates a relational database
