But the ODI CDC must require the source table to have a primary key.second, the problem of deleting data introducedWhen we start using ODI for data synchronization in CDC mode, everything is OK, and the deleted data can be correctly synchronized to the target database. Then, becauseBusiness requirements, we only need to synchronize some of the data to the target databa

ETL ConsiderationsAs a data warehouse system, ETL is the key link. Said Big, ETL is a data integration solution, said small, is to pour data tools. Recall the work over the years, the processing of data migration, conversion is really a lot of work. But those jobs are basically a one-time job or a small amount of data, using Access, DTS, or making a small program

Assembly Area Preparing data, often also called data management, refers to acquiring data and translating it into information, and ultimately submitting that information to the front-end query interface. The background does not provide query services, the Data Warehouse methodology assumes that data access in the background is strictly forbidden, which is the sole purpose of the foreground. The backend part of the data warehouse is often referred to as the staging area (Stagingarea). Data aggreg
