條目服務 （ES） 3.1 是 Java 開發人員的軟體庫。它通過類型化物件（條目）的單個層次結構提供對分散式數據的集中訪問。條目可以儲存在不同類型的數據來源（XML 檔、RDBMS等）中。每個數據源都使用一個條目服務進行過度構建;服務一起分組到一個分散式層次結構中。每個服務發佈其自己的部分的全域條目（物件）樹。整個入口樹可以通過運行的任何服務訪問，通過一個程式介面，儘管物件存儲在何處以及如何實際上。所有服務以透明方式提供相同的數據視圖。 條目具有穩定且唯一的字串標識符，可從任何位置引用;標識符顯示條目嵌套結構。條目嵌套和服務層次結構彼此獨立，因此條目可以移動到另一個服務，而無需更改其標識符。存在 ES 路徑（XQuery/XPath 樣語言）來查詢項目樹。 分散式可刷新對像是該庫的基礎，這為 ES 增加了更大的靈活性和效率：一組遠端呼叫通過網路收集並作為一個包發送;所有遠端項目都緩存在用戶端上，無法存儲陳舊資料;在條目更改時可以進行訂閱。所有這一切都是在沒有任何消息伺服器（發生點對點通信）中完成的，這為條目樹提供了非常高的可伸縮性，並有可能在全域範圍內使用它。 主要特點是： - 覆蓋任何類型的資料來源（RDBMS、XML等）的類型化物件的單個檢視。 - 穩定字串物件標識符，可從任何地方引用;支援回引用導航; - XQuery/XPath 樣 ES 路徑語言，以查詢整個樹。 - 遠端項目在本地快取;不可能有陳舊的數據。 - 無需中央消息伺服器通知更改;提高可擴充性。 - 有效的網路資料交換
