there are often a wide variety of answers. Therefore, you must be careful when selecting a solution. If you don't give it a try, it will often be counterproductive.5. prompt to use program: zdmdeltarepair to fix the problem. After reading the original code, this is the first solution to solve the problem. We already have a lot of data, so the line is different, however, this program found two very important tables: the Delta control table rsdmdelta and rsbodslogstate, which store the following

Abstract: Based on the Data Storage Technology of ODS in the middle layer of DB and DW, a real-time OLAP system for commercial systems is designed from the perspective of application. ODS is used to overcome the problem that DW is too bloated for decision-making and is not suitable for enterprises' real-time middle-level decision-making.
Key words: Data Warehouse (DW), operational data storage (
is, how to solve such a problem. As a follow-up, the birth of the operational data store (operational, ODS) provides a good solution to such problems. In theory, what is the difference between these two solutions? Now get to the point.
The main differences between ODS and DW are as follows:
1, the current nature of the data
ODS includes current or near-current d
ODS is a topic-oriented, integrated, variable, and current collection of detailed data. It is used to support enterprises' demand for instant, operational, and integrated information. It is often used as a data warehouse transition and is also an option for data warehouse projects.
According to the definition of Bill. inmon, "Data Warehouse is subject-oriented, integrated, stable, and time-changing, mainly used for decision-making support of datab

ODS output format: listing (default standard SAS output), HTML, RTF, prtnter, PS, PCL, PDF, output (SAS output date-set), markup, and document;
ODS contains the table template (specified output structure) and style template (specified appearance structure): first, the table template function generates data from procedure to form the outp

Log is usually output in the log window. The default output location can be changed using the printto process.
Proc printto log = "D: \ log.txt" New; * output the log to the specified file. "New" indicates that the previous file is overwritten. For more information, see the help document; proc print data = sashelp. class; proc printto; run; * Restore Default log output;

loading data by itself, and loading data from DSO to another DSO or cube, a new request may be imported due to frequent deletion of the primary request.
1. view the table rsdmdelta (Dataset Delta Management) by DSO name. If the partid field has a value, the incremental loading cannot be repaired. See note 578150.
2. Otherwise, view the rsbodslog table (requests in ODS change logs) and obtain the maximum value of the requid field.
3. Check the rsbodsl
I recently made a mistake and was impressed with changelog, which is summarized as follows:
1. For the data source generated by ODS (the data source starting with 8), the PSA is the changelog table of ODS, so it will be automatically loaded without creating an information package.
2. If you delete the request from this data source, in ODS, the changelog of the
