Aspire is a RAD tool that provides users with a standard xml/xsl, Java EE, and relational database technology to quickly create a Web site. The Aspire acceptable sources include stored programs, SQL statements, EJBS, and Java controls, and use Apache's Xerces/xalan as the converted processor.
Aspire can be used for a variety of servlet engines, such as Apache/jserv, Apache/tomcat, and WebSphere.
The current development features include a consolidated interface for reporting tools such as Cryst
When we merge two identical or similar dataset objects in ADO. NET, we typically use the dataset's Merge method, which has multiple overloaded versions, and we review the merge method before introducing it, and here's how to use the merge method in MSDN:

This document assumes that you are familiar with ADO. NET and Visual Basic. net.
Summary
Many technologies provided by ADO. Net can improve the performance of medium-sized dataset applications and make it easier to build such applications. Dataset is a flag of the ADO. Net object model and can be used as a small, disconnected copy of the data sou
Because of the two principles, the dataset's reputation has been badly screwed up. First, it is inconvenient to use an XML-serialized dataset to interact with other non-. NET code. If the dataset is used in the Web Services API, it is not used with the other. NET Framework, it can be very difficult to interact with the system. Second, it is a very general container. You can cheat by cheating. NET Framework,

Although Ado.net is a successor to the. NET platform, the difference between the two is great. DataSet objects in the Recordset objects and ado.net that are highlighted in ADO. The recordset is also a very flexible object, Microsoft launched it also painstaking, such as: The Recordset can be offline operation of the database tutorial, good performance, high efficiency, etc. these all let the then programmer spirits. Although the recordset is already c
This article introduces the detailed description of dataset in javascript, including the basic usage of dataset, the role of dataset, and basic operations of dataset, if you are interested in javascriptdataset, let's learn it. DataSet is ADO. NET.
In these days I 've read into different opinions about dataset and custom entities. Here is my personal point of view.

Dataset are not participant ly optimized when you serialize them with either xmlserializer or formatters runtime serialization, at least until the release of. NET Framework 2. 0...

And because the DataSet object has the characteristics of offline access to the database, it can be used to receive a

In Server Explorer, expand the Northwind data connection until you can see all the tables.
Creating data Adapters and connections
This step creates connections and data adapters that are used to connect and exchange data between applications and data sources.
Creating data Adapters and connections
Drag the Customers table from the Server Explorer (Server Explorer) onto the form. The connection and data adapters are displayed in the component tray.

Dataset is a method used to connect to SQL. It means to store copies of the database in applications.ProgramWhen the application starts running, save the database-related data to dataset.Datatable indicates a table with data in memory. You can use view to obtain a custom view of a table that may include a filtering view or a cursor position.The datareader object is the simplest way to read the database. It can only read, cannot write, and is read from
The dataset is the central concept of ADO. Datasets can be treated as an in-memory database, which is a separate collection of data that is not dependent on the database. The so-called independence, that is, even if the data link is disconnected, or shut down the database, the dataset is still available, the dataset is internally XML to describe the data, because
The last time I started the Web report development technology topic from a small serial number, I will talk about the core of the Web report development tool-dataset transformation.
