Overview of projects, studies, and libraries
Characteristic | Description |
---|---|
About projects | Projects are containers used to hold study design building blocks. You can create two types of projects:
|
Number of studies and libraries to create | You can create one library in each library project. There is no limit on the number of studies you can create in a study project. However, you might experience performance degradation if you have multiple studies in a single project, especially if the number of study objects is large. |
Contents | Studies and libraries contain the same types of study objects. A study object is a study building block that appears in the Project Explorer. |
Repository | All study objects and components are stored in a single database instance called the repository. The repository can be organized into multiple libraries, each of which can be managed differently and can serve a different purpose. For example, you can organize libraries by therapeutic area or by team. Central Designer libraries store study objects for reuse and help enforce standards. A library project is a project containing a library. A library is a container used to store related study objects and templates to be published for reuse in studies or other libraries. A library provides a logical view of the study objects in the repository. A librarian creates libraries within library projects and then includes resources from the repository or defines new resources within the library itself. If you have the appropriate rights (assigned in the Central Designer Administrator application) and you are a member of the library team, you can:
|
Reuse | Study objects that are created in libraries can be copied easily into multiple studies. Additionally, study objects that are created and saved in studies are available for reuse when copied directly from the repository. |
System library | Oracle recommends that you do not modify information in the System Library. Instead, copy item types from the System Library to another library, and modify information in the new library. When you create an item, you can choose to base it on any of the types in the libraries in the Library List, so make sure you add the new library to the list. Optionally, if you do not want the item types in the System Library to appear as options, you can remove the System Library from the Library List. |
