psychographic data sources

In SSIs, most data sources direct to a connection manager. by specifying a Connection Manager, you can reuse the connection in the package so that all connections can be reset once, there are 6 different data sources in SSIs. OLE DBData Source The ole db data source i

[Spring] uses Spring's AbstractRoutingDataSource to implement multi-data source switching. spring dynamically switches data sources. Recently, because the project needs to synchronize data between two projects, specifically, Project 1 data is synchronized to project 2 throug

In the previous section, we talked about multiple data scenarios:1. Different data sources (different database vendors, different business scope, different business data)2. Unlike SQL mapper files,3. MyBatis + Data dialect differentThat is, the simplest multi-

Label:First, why use data sources and connection poolingThe applications that are now being developed are basically data-based and need to be connected to the database frequently. If you connect to the database each time and then close, this performance is bound to be limited. So, we must try to reuse it.The connection to the database. Therefore, the concept of

After several years of data binding, we will summarize which objects can be used as data sources for data control. The following text is from Microsoft's msdn. Use the datasource attribute to specify the source of the value to be bound to the data list control. The

Recently in doing a very simple small project, although simple, but also encountered a lot of problems, now roughly recorded: The project is basically divided into two main modules: I do this piece, with the current universal SSH framework to maintain two tables, a user table, an Account table, two tables have no connection, everything is smooth. The other is a colleague to do another module, is a timer task, set a fixed time interval, every time this period will carry out this task, carried out

In our project, we encountered the problem of connecting multiple databases to our projects, and different clients accessing different databases as needed in each visit. We used to always configure a data source in the spring and hibernate frameworks, so the DataSource property of Sessionfactory always points to this data source and remains constant, All DAO uses this d
