Learning from past support issues, you ve noticed that you receive many frantic customer calls related to a problem stemming from incorrect jvm versions and incorrect object-relational mapping 從過(guò)去的支持問(wèn)題中,您注意到許多急切的客戶電話都與錯(cuò)誤的jvm版本和錯(cuò)誤的對(duì)象關(guān)系映射(orm)所導(dǎo)致的問(wèn)題有關(guān)。
This flexible and portable programming model abstracts the data access layer using an object to relational mapping layer and the enterprise javabean query language ejb-ql 這個(gè)靈活且可移植的編程模型使用對(duì)象至關(guān)系映射層和enterprisejavabean查詢語(yǔ)言(enterprisejavabeanquerylanguage,ejb-ql)抽象了數(shù)據(jù)訪問(wèn)層。
In this article, we ll examine a basic example that illustrates how hibernate works and puts to good use three different strategies under which you can use hibernate to do your object-relational mapping 在本文中,我們要研究一個(gè)基本示例,演示hibernate如何工作,如何良好地運(yùn)用三個(gè)不同策略,利用hibernate進(jìn)行對(duì)象關(guān)系映射。
In the second part of the object-relational mapping see table 2, classes are mapped to tables, scalar properties are mapped to columns, and pointer reference properties are mapped to primary key foreign key relationships 對(duì)象-關(guān)系映射的第二部分(參見(jiàn)表2)中,類映射到表,標(biāo)量屬性映射到列,指針/引用屬性映射到主鍵/外鍵關(guān)系。
Both hibernate and rails persistence frameworks can be classified as object relational mapping tools, meaning that they take an object view of the data and map it to tables in a relational database hibernate和rails的持久性框架可以歸類為對(duì)象/關(guān)系映射(orm)工具,這意味著它們接受數(shù)據(jù)的對(duì)象視圖,并將該視圖映射到關(guān)系數(shù)據(jù)庫(kù)內(nèi)的表中。
Hibernate and java data objects, which both form the foundation of the new ejb persistence and a common persistence standard, led to a rise in object-relational mapping within the java community, and now the overall java experience is a much more pleasant one hibernate和java數(shù)據(jù)對(duì)象(jdo)二者構(gòu)成了新的ejb持久性的基礎(chǔ),成為公共的持久性標(biāo)準(zhǔn),它們引起了java社區(qū)中對(duì)象關(guān)系映射(orm)的興起,現(xiàn)在整體的java體驗(yàn)要好得多了。
There are many sql monitors, oo-relational mapping tools and other database utilities already available as eclipse plugins, which are independent of the database and could be used alongside our hsqldb plugin to provide a complete environment for this kind of developer 有很多sql監(jiān)控器、oo-關(guān)系映射工具和其他數(shù)據(jù)庫(kù)實(shí)用工具都可以作為eclipse插件得到,它們獨(dú)立于數(shù)據(jù)庫(kù),可以與我們的hsqldb插件共同為此類開(kāi)發(fā)者提供一個(gè)完整的環(huán)境。
In this second tutorial of a three-part series, learn more about how you can improve persistence in your database-driven java applications by combining apache derby s power as a small-footprint embeddable database with the ibatis object-relational mapping framework 在本共分三部分的系列教程的第二部分中,將學(xué)習(xí)如何把a(bǔ)pachederby作為資源占用小、可嵌入數(shù)據(jù)庫(kù)的能力與ibatis的對(duì)象關(guān)系(or)映射框架結(jié)合,從而改進(jìn)數(shù)據(jù)驅(qū)動(dòng)的java應(yīng)用程序的持久性。
Hibernate has a number of advantages over other similar object-relational mapping approaches jdo, entity beans, in-house development, and so on : it s free and open source, it has achieved a good level of maturity, it s widely used, and it has a very active community forum 比起其他類似的對(duì)象關(guān)系映射技術(shù)(jdo、實(shí)體bean、內(nèi)部開(kāi)發(fā)等),hibernate有許多優(yōu)勢(shì):它是免費(fèi)的、開(kāi)源的,已經(jīng)成熟到良好的程度,并得到廣泛應(yīng)用,而且還有一個(gè)非?;钴S的社區(qū)論壇。
Then, it explores struts framework on the basis of mvc mode and data persistence frame hibernate, paying more attention to discuss how struts realizes mvc mode and how struts ’ modules works together . in addition, the java object persistence technology principle and the hibernate object relational mapping frame realization mechanism and the work principle are studied 接著對(duì)一個(gè)基于mvc模式的struts框架和數(shù)據(jù)持久性框架hibernate的進(jìn)行研究,著重于討論struts是如何實(shí)現(xiàn)mvc模式以及struts的各組件是如何協(xié)同工作的,研究了java對(duì)象持久化技術(shù)原理及hibernate的對(duì)象關(guān)系映射框架實(shí)現(xiàn)機(jī)制及工作原理。
