In this issue, the editor will bring you about how to analyze the use of ADO data mapping. The article is rich in content and analyzed and described from a professional point of view. I hope you can get something after reading this article.
ADO data and DataSet: describes how DataSet interacts with XML as a data source (including loading and maintaining DataSet content as XML data. You can run local ADO objects in your own program by right-clicking on references node.
DiffGram: provides more information about DiffGram, a XML format for reading and writing DataSet content. Loading DataSet from ADO data: discusses the different options to consider when loading DataSet content from an XML document.
Writing DataSet as ADO data: discusses how to generate the content of DataSet in the form of XML data and the different XML format options available. Load DataSet schema information from XML: discusses the DataSet method for loading DataSet schemas from XML.
Write DataSet schema information as ADO data (XSD): discuss the purpose of XML schemas and how to generate XML schemas from DataSet. Synchronizing DataSet with XmlDataDocument: discusses the relationships that synchronize access to a single dataset and the features available in the .NET Framework with a hierarchical view, and explains how to create a synchronization relationship between DataSet and XmlDataDocument.
Nested DataRelation: discusses the importance of nested DataRelation objects in representing DataSet content in the form of ADO data and describes how to create these objects. Generate DataSet relational structures from XML schemas (XSD): describe the relational structures (that is, schemas) of DataSet created from XML Schema definition language (XSD) schemas.
Map ADO data (XSD) constraints to DataSet constraints: describes the XML schema elements used to create * and foreign key constraints in DataSet. Generate DataSet relationships from XML Schema (XSD): describes the XML schema elements used to create relationships between table columns in DataSet.
Understand the interrelationships between constraints and relationships: describes how to create relationships implicitly when using XML schema elements to create constraints in DataSet. Infer the DataSet relational structure from the XML: describes the resulting relational structure (that is, the schema) of the DataSet created when inferring from the XML element. Create and use data tables: describes how to create and customize DataTable objects.
Create data Table: explains how to create ADO data and add it to DataSet. Define the schema of the data table: provides information about creating and using DataColumn objects and constraints. Manipulate data in a data table: explains how to add, modify, and delete data from a table. Describes how to use the DataTable event to check for changes to data in a table.
The above is the use of how to analyze ADO data mapping shared by the editor. If you happen to have similar doubts, please refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
