The ABZ-MOSAIC Data Trending System is a computerized modular tool for storing, retrieving, trending, and evaluating test data. The system was designed to trend data from tests required by ASME Section XI. However, there is nothing inherent in the system that limits the system to this function. In short, the system is capable of storing and trending any test data.

The ABZ-MOSAIC Data Trending System is a menu-driven, interactive system that can be easily mastered by individuals who have little or no programming experience. Passwords and access levels ensure that only authorized users can make changes to stored data or add new data. All interactions with the system must conform to pre-defined data entry templates or option selections. Context-sensitive help is available at all points in the system.

The ABZ-MOSAIC Data Trending System provides routine database operations such as deleting, modifying, archiving, and displaying data. The data displays include both tabular and graphic formats. More importantly, the system automatically calculates the allowable limits for measured values and compares the actual measured values against the calculated limits. The limits are calculated in accordance with ASME Section XI requirements or other user-defined rules if desired.

The limit calculations involve calculating two sets of limits. The absolute limits correspond to the Action Required limits in Section XI. The max and min values are calculated by the system based on the parameter type and the reference value. All data entered or modified are compared to these limits and appropriate warnings displayed if exceeded.

The second limits are the administrative limits. These correspond to the Alert Range limits of Section XI. These limits are stored in data fields that are not displayed on the screen and are also calculated based on parameter type and reference value. Although not displayed, whenever data are entered or modified, the data are compared against these limits. If these limits are exceeded, a message is displayed stating this, along with the value of the limit.

The ability exists within the limit calculation rules for either or both limits to be ignored for specific parameters. For example, the rules concerning the limits on measured vibration have no minimum or lower administrative limits.

The ABZ-MOSAIC Data Trending System can be modified by the user. Except for certain primitive functions and control structures, the rules employed by the system are transparent and logically arranged. Simple changes necessary to support system maintenance can be easily changed by someone who receives a modest amount of training.

ABZ provides documentation and training for the ABZ-MOSAIC Data Trending System. The documentation includes a user manual and technical reference guide. The training includes a one-day onsite training session.
