透明和可控的ORMXPO是一個對象關(guān)系映射(ORM)工具,能完成數(shù)據(jù)庫的創(chuàng)建和對象持久化等各方面的工作,讓你能專注于應(yīng)用程序的業(yè)務(wù)邏輯。你所要做的就是定義持久化對象類,XPO會自動生成相應(yīng)的數(shù)據(jù)庫結(jié)構(gòu)。通過使用.NET Reflection和內(nèi)置屬性,XPO將業(yè)務(wù)對象的屬性映射到數(shù)據(jù)庫表格中。完全支持對象關(guān)系 (一對一、一對多、多對一)、聚合和繼承。 | |
交叉DBMS連接有了XPO,你的代碼無需做任何改動就可以創(chuàng)建運行于多個數(shù)據(jù)庫系統(tǒng)的應(yīng)用程序。支持大部分當(dāng)今最流行的數(shù)據(jù)庫引擎,包括MS SQL Server、PostgreSQL、MySQL和Oracle。當(dāng)然SQL Azure也全面支持你將數(shù)據(jù)存儲在云中。由于一個實際數(shù)據(jù)庫可以替代內(nèi)存數(shù)據(jù)存儲,因而輕量級的單元測試可以覆蓋數(shù)據(jù)模型。 | |
輕松重利用現(xiàn)有數(shù)據(jù)庫包含逆向工程遺留數(shù)據(jù)庫結(jié)構(gòu)和自動生成持久對象代碼,使得傳統(tǒng)的關(guān)系數(shù)據(jù)庫能輕松的轉(zhuǎn)變?yōu)閄PO。設(shè)計器能可視化生成的數(shù)據(jù)模型,而且可以實現(xiàn)定制化。此外,改向?qū)н€生成了輔助性的helper對象,允許你直接調(diào)用現(xiàn)有的存儲過程并處理結(jié)果。持久化對象和需要映射到數(shù)據(jù)庫視圖的DDL代碼也都可以自動生成。 | |
數(shù)據(jù)模型設(shè)計器你可以在一個可視化設(shè)計器中初步創(chuàng)建數(shù)據(jù)模型,而并不需要編寫代碼,可以向設(shè)計器中添加新的對象,指定對象關(guān)系以及定義持久和適合的屬性。此設(shè)計器還能在單個window窗口可視化整個數(shù)據(jù)模型,并且自動創(chuàng)建相關(guān)XPO對象。 | |
查詢和過濾功能你可以使用與VB.NET和C#相似的面向?qū)ο笳Z法指定檢索、排序和過濾的標(biāo)準(zhǔn)。此功能提供了許多有用的操作,包括自由連接、向上轉(zhuǎn)型和聚合,同時也支持對持久化對象的LINQ查詢。 | |
適用于分布式系統(tǒng)XPO能輕松地應(yīng)對復(fù)雜的分布式應(yīng)用。你可以屏蔽直接的數(shù)據(jù)庫連接,降低通過Web Services、WCF和Remoting跨數(shù)據(jù)發(fā)布線傳輸?shù)臄?shù)據(jù)量。同時你可以輕松的創(chuàng)建OData服務(wù),將數(shù)據(jù)傳輸?shù)较馜XTREME移動應(yīng)用的任何兼容ODdata的客戶端。 | |
可綁定集合與服務(wù)器模式XPO能幫助你檢索持久化對象集合,并將它們輕松地綁定到WinForms、ASP.NET、WPF和Silverlight控件。例如,當(dāng)綁定一個集合到像XtraGrid的網(wǎng)格控件時,對象可以表示成網(wǎng)格中的可編輯記錄,網(wǎng)格的列代表對象的屬性。設(shè)計了Server Mode綁定以處理大數(shù)據(jù)集,當(dāng)使用時,數(shù)據(jù)識別操作都在服務(wù)端執(zhí)行并根據(jù)需要使用控制項小規(guī)模加載數(shù)據(jù)。 | |
異步數(shù)據(jù)加載異步數(shù)據(jù)加載可能會很耗時,并且在數(shù)據(jù)加載完畢之前,你的用戶界面反應(yīng)非常遲鈍。為了避免這種情況,XPO在異步加載數(shù)據(jù)時提供了一個快速響應(yīng)的界面,即使數(shù)據(jù)集非常大也能完成。當(dāng)向數(shù)據(jù)源發(fā)送請求后,數(shù)據(jù)檢索發(fā)生在后臺線程,同時綁定網(wǎng)格控件繼續(xù)響應(yīng)用戶的操作。 | |
對象和數(shù)據(jù)層緩存數(shù)據(jù)庫中每進(jìn)行一次查詢,XPO會檢查數(shù)據(jù)庫中相關(guān)對象的最新版本,并在需要時更新對象緩存。同時,XPO 緩存查詢和結(jié)果也同時在數(shù)據(jù)庫服務(wù)器上被執(zhí)行。每當(dāng)之前的執(zhí)行的查詢操作信息經(jīng)過緩存區(qū)時,查詢結(jié)果都會立即反饋到客戶端,無需經(jīng)過服務(wù)器。 | |
分析和調(diào)試XPO附帶了一個實用的效能評測器,可以幫助你發(fā)現(xiàn)性能瓶頸和代碼漏洞。與服務(wù)端SQL查詢分析器不同,XPO效能評測器運行在客戶端,并且能跟蹤內(nèi)部XPO事件。這個效能評測器為你提供了有傳遞參數(shù)的方法調(diào)用日志和并行SQL查詢記錄,這種整合的日志比僅僅是執(zhí)行操作列表記錄更有用。并且,由于XPO語境驅(qū)動適用于這個工具,因而你可以通過運行LINQPad中的交互式LINQ查詢來完成各種調(diào)試任務(wù)。 |

Transparent and Controllable ORMXPO is an Object-Relational Mapping (ORM) tool that handles all aspects of database creation and object persistence, allowing you to concentrate on your application's business logic. All you need is to define persistent object classes, and XPO will generate the appropriate database structure automatically. By using .NET Reflection and built-in attributes, XPO maps the properties of business objects to relational database tables. Object associations (one-to-one, one-to-many, many-to-many), aggregation and inheritance are all fully supported. |
|
|
Cross-DBMS ConnectivityWith XPO, you can build applications that work with multiple database systems without making any changes to your code. More than a dozen of today's most popular database engines are supported, including MS SQL Server, PostgreSQL, MySQL and Oracle (see more). And of course you can host you data in the cloud, as SQL Azure is fully supported. The data model can be covered with lightweight unit tests because a memory data store can be used instead of a real database. |
|
|
Easy Reuse of Existing DatabasesA wizard that reverse engineers the legacy database structures and automatically generates persistent class code is included. This allows for an easy transition from traditional relational databases to XPO. The generated data model is visualized by the designer and can be easily customized. Additionally, the wizard can generate auxillary helper classes that allow you to directly call existing stored procedures and handle results. Persistent classes and DDL code required to map database views can be auto-generated as well. |
|
|
Data Model DesignerYou can chose to draft the data model within a visual designer instead of writing code. In this designer, you can add new objects, specify object relationships, as well as define persistent and calculated properties. The designer visualizes the entire data model in a single window and creates the underlying XPO classes automatically. |
|
|
Queries and FiltertingYou can specify retrieval, sorting and filtering criteria using object-oriented syntax similar to VB.NET and C#. This capability provides a number of useful operators including free joins, upcasting and aggregates. LINQ queries against persistent objects are supported as well. |
|
|
Applicability for Distributed SystemsXPO is ready for complex distributed applications. You can shield direct database connections and reduce the amount of data that travels across the wire publishing data via Web Services, WCF and Remoting. In addition, you can easily create OData services that expose data to any OData-compatible clients like DXTREME mobile applications. |
|
|
Bind-able Collections and Server ModeWith XPO, you can retrieve collections of persistent objects and bind them to WinForms, ASP.NET, WPF or Silverlight controls with ease. For instance, when a collection is bound to a grid control like XtraGrid, objects can be represented as editable records in the grid and object properties represented by grid columns. Server Mode binding has been designed to work with large datasets and when used, data-aware operations are performed on the data server side and bound controls load data in small portions, on demand. |
|
|
Asynchronous Data LoadingSynchronous data loading operations can be time consuming, and your UI can become unresponsive until all data is loaded. To avoid such a situations, XPO can load data asynchronously and therefore provide a fast and responsive UI even against very large datasets. After sending a request to a data source, a bound grid control continues responding to user actions while data is being retrieved in a background thread. |
|
|
Object and Data Layer CachingEvery time a query to the database is made, XPO checks for new versions of the relevant objects in the database and updates the object cache when required. In addition, XPO caches queries and their results as they are being executed on the database server. Whenever a query passes the cache that has been executed previously, the result from that query is returned to the client immediately, without a roundtrip to the server. |
|
|
Profiling and DiagnosticsXPO is shipped with a Profiler - a utility that helps you find performance bottlenecks and code issues. Unlike server side SQL query profilers, XPO Profiler runs at the client side and tracks internal XPO events. The profiler provides you with a log of method calls along with passed parameters and corresponding SQL queries side-by-side. This combined log can be much more helpful than just a list of executed queries. Furthermore, you can solve various diagnostic tasks by running interactive LINQ queries in LINQPad, as the XPO context driver is available for this tool. |
