級聯刪除 的英文怎麼說
中文拼音 [jíliánshānchú]
級聯刪除
英文
cascade delete-
Cascading deletes are a scary concept initially
級聯刪除起初是一個可怕的概念。Cascaded low - density erasure codes are based on sparse random bipartite graphs. very efficient linear time encoding and erasure recover algorithms with the arbitrarily near erasure channel capacity performance of the codes with respect to the algorithms have made them one of the most optimal coding techniques up to now
基於稀疏隨機二部圖的級聯型低密度糾刪碼因其線性時間的編譯碼演算法和可任意逼近刪除通道容量限而成為目前最佳編碼技術之一。The principles of erasure codes used under binary erasure channels are summarized and erasure codes which belong to standard classes of rs codes are introduced with emphasis on cascaded low - density erasure codes with linear time encoding and erasure recover algorithms. thresholds of regular degree distributions are analyzed. it is shown that low - density erasure codes based on ( d, 2d ) - regular sequences of degree distribution are not close to optimal ( d 3 ). two pares of irregular degree distribution sequences are introduced and a pare of improved right regular sequences of low - density erasure codes are presented, it is testified that the new sequences are asymptotically quasi - optimal. in the meantime, simulations of cascaded low - density erasure codes based on a few types of special sequences of degree distribution available are given, together with performance analyses on these codes
闡述了應用於刪除通道下的糾刪碼基本原理，介紹了兩類標準的rs碼類糾刪碼，重點分析了具有線性時間編碼和恢復演算法的漸近好碼?級聯型低密度糾刪碼，分析了正則度分佈的閾值，對正則低密度校驗碼在刪除通道下的糾錯性能進行了模擬，從理論上證明了基於（ d ， 2d ） -正則度序列的低密度糾刪碼都不是漸近最優碼（ d 3 ） ，同時還分析了非正則低密度校驗碼的度序列設計，基於右邊正則序列提出了一種改進型右邊正則序列，證明了此序列為漸近擬最優的，對基於幾類現有典型度分佈序列的級聯型低密度糾刪碼進行了模擬模擬及性能分析； 3Relationship should not trigger a cascading delete
關系不應觸發級聯刪除。Relationships defined, you may trigger a cascading delete
關系，則有可能會觸發級聯（ cascading ）刪除。Cascade delete in database speak
級聯刪除） 。For database cascading delete
級聯刪除Cascade deletes all rows containing data involved in the foreign key relationship
級聯刪除包含外鍵關系中所涉及的數據的所有行。Now that you know all about cascading deletes and you ve promised to be careful, you can see the actual code to execute the embedded
如果您已經完全了解了級聯刪除，並保證會多加小心，那麼您就可以來看執行嵌入的This successful execution includes all referential cascade actions and constraint checks associated with the object updated or deleted
判斷執行成功的標準是：執行了所有與已更新對象或已刪除對象相關聯的引用級聯操作和約束檢查。分享友人
