De-normalized Oracle views, termed data extract views, are created with SQL statements; these views join together and organize the study data so that responses to DCM questions are presented in the context of study, Investigator, patient, and RDCM.
For every Oracle view created, a corresponding SAS view is also created. Default View Creation Algorithm Data extract is always done at the study level, either within a single study or across multiple studies.
You can perform this default when the DCM is activated, or on an ad-hoc basis by choosing Default View Definition from the Special menu. Data extract views are created as follows: The name of the data extract view is the DCM short name.
These views are created for this DCM: If a third non-repeating question group is added to this DCM, the data is included in the existing ET view; but if another repeating group is added to the DCM, another view is created.
View Types Data extract views fall under the following categories: Current views display all data, including data not yet validated. Test type accounts create data extract views for provisional view definitions, while the Current account creates data extract views for active view definitions only for View Builder-enabled studies.
Stable views display only data that has been made accessible through data entry and has been through Batch Validation. A Stable view looks the way it did after completing its last Batch Validation.
Snapshot views display data as it looked at a particular moment in time during the data collection process. You can pick any Batch Validation run time stability point as the base date for a snapshot.
Rolling Snapshots are refreshed on demand to reflect the current Stable view of the data.
Once you have defined and created the data extract views, you can submit batch jobs to create SAS datasets and SAS Proc Prints, and then analyze the data.
Rollsnaps The Rolling Snapshot—or Rollsnap—account is a study access account for holding data extract tables equivalent to Stable accounts, except that data extraction has to be explicitly run to update its contents.
A system-defined snapshot, Rollsnap, is created and automatically updated to reflect the Batch Validation timestamp at the last table refresh. Maintenance of this account can therefore be scheduled asynchronously with Batch Validation.
For instance, if Batch Validation runs nightly, the Rollsnap account could be refreshed on a weekly basis. If required, the Rollsnap account could be refreshed after each Batch Validation and always reflect the latest Stable account.
View definitions created as views and not tables in this account view their data as of the Snapshot timestamp and thus are consistent with the data extracted to tables. Access Accounts In creating a clinical study state for a study from the Conduct menu, select Security, then select Clinical Study Statesyou automatically create access accounts.
These accounts are owned by one of the following kinds of account — Current, Stable, Rollsnap or Test. The only accounts you can create are Snapshot accounts. The batch job allows you to remove one access account at a time; you cannot remove all the accounts from a particular study.
To run this job: The PSUB window for this job opens. Run or schedule the job. Table-Based Views The Table-Based Views option is available for all accounts, and enables you to specify that particular access accounts will contain Oracle tables of extracted data instead of views. You can also control indexing of these tables.
Despite its name, the Table-based Views option still enables you to see views with the names of DCMs or View Definitions that are based on the data extract tables.
When you create a table-based view, you need to choose a tablespace for tables and one for indexes that is large enough to meet your needs.
The Maintain Study Access Accounts window provides fields for you to enter these tablespaces.
See the OracleAS10gR2 documentation for information about calculating the space needed. Union views cannot be represented as tables. Creating Extract Tables and Indexes Although indexing is a task that could be considered better covered under the Definition subsystem in Oracle Clinical, it is treated here because the menu entry is under Conduct.So certain was he as to the exact locality, that he offered to conduct a party to the place.
