ADO is a consumer of old db that provides access to OLE DB data sources at the application level. Using OLE DB and ADO in your application, you can efficiently i

and a specific database. In this way, as long as the application provides the data source name to ODBC, ODBC can establish a connection with the corresponding database. Ii. OLE DB The origin of OLE-DB As data sources become increasingly complex, today's applications may need to obtain and process data from different data sources, and then output the processed data to another data source.

DB, abbreviated as database, is the carrier of data storage in PDMS. The various three-dimensional models, graphic drawings, databases, and so on in PDMS are almost always stored in db. So once the DB has an exception, the consequences will be devastating, so we need to have some technical means to deal with the DB pro

After studying Oracle for a long time, I would like to share with you that you will certainly have a lot of gains after reading this article. I hope this article will teach you more things. After the compiled code is generated, the next step is to prepare the server process to start updating the data. The server process will go to the Oracle db buffer to check whether there is any cached data for the relevant objects. The following two possible explan
