Database management systemExpert systemSemantic modelObject-oriented programingFlow cytometryObjects play a major role in both database and artificial intelligence research. In this paper, we present a novel architecture for expert database systems that introduces an object-based interface between ...
A Brief Review of Serializability 主要有三大类实现并发控制的方法: Strict two-phase locking(2PL) Multi-Version Concurrency Control(MVCC) Optimistic Concurrency Control(OCC) Locking and Latching 数据库会自己实现一个锁控制系统,称为Locking。数据库系统会自己维护一个Lock Table记录Transaction/Lock/Object之间...
In recent years, object database systems have emerged as a new technology, integrating object‐oriented paradigms with transaction and query capabilities of conventional database systems. The strength of distributed object database systems is further enhanced by new generations of powerful workstations....
业务层里的customer object聚合了业务请求需要的所有信息(在这个例子里获取客户信息)。这个模块调用持久层中的 customer dao 来得到客户信息,调用order dao来得到订单信息。这些模块会执行SQL语句,然后返回相应的数据给业务层。当 customer object收到数据以后,它就会聚合这些数据然后传递给 customer delegate,然后传递这些...
This is achieved by read requests acquiring a read lock before accessing an object, and unlocking it immediately after access. REPEATABLE READ: A transaction will read only one version of committed data; once the transaction reads an object, it will always read the same version of that object....
COLA 是 Clean Object-Oriented and Layered Architecture的缩写,代表“整洁面向对象分层架构”。目前COLA已经发展到COLA v5。 想了解更多COLA信息,请关注微信公众号: 想了解更多COLA背后的故事,请支持我的新书《程序员的底层思维》 COLA分为两个部分,COLA架构和COLA组件。 一、COLA架构 COLA 概述 架构的意义 就是 ...

方案1:Object Dependency Inject 这个方案在早期的时候做过尝试,简单的来说就是将中间那段emitMessageEntry相关的代码抽象成一个接口的方法,并在实现代码中填入现在的逻辑,并通过spring这种IOC框架注入进来,类似于: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 kotlin复制代码 override fun prepare(topoConf: Mu...
