What is Vo2Ado
Vo2Ado offers the VO developer two ways to access data.
- ADO Wrapper classes
- ADO DataServer classes
- ADOX Classes
- Classmate compatible Server class (Professional Version Only)
- VO Sql compatible classes (Professional Version Only)
- VO2Ado RDD (Professional Version Only)
The ADO Wrapper classes are set of very thin classes build on top of ADO. These classes translate VO data-types to ADO and back and handle all the ‘hassle’ of COM for you. These classes are written in a very efficient way, so you’ll get the best possible performance.
The ADO DataServer is a DbServer compatible class that allows you to use data from ADO in combination with the VO data-aware classes, such as DataWindow, DataBrowser and DataListView. There is also a special DataServer class that allows you to use hierarchical (Shaped) datasets, and make them look like a set of related DataServers.
VO2Ado also has a set of ADOX classes (the Microsoft Ado Extensions for DDL and Security). These classes allow you to manipulate the structure of your Microsoft Databases, and set up security rights etc. ADOX right now only work with some providers such as Ms SQLServer, Oracle, ODBC and the Microsoft Jet Engine.
The Classmate compatible Server class allows you to use VO2Ado as datasource in your classmate applications
The SQL Compatible classes allow you to quickly use Vo2Ado in an existing application based on the VO SQL Classes
Finally the VO2Ado RDD allows you to quickly convert a RDD based applications
