Eagle Analytics uses rules based architecture with configurable, proprietary elements, such as calculation rules, calculations, functions, and input/output parameters. The following figure shows the component architecture at a high level.

The key elements within the Eagle Analytics architecture are listed below.

Calculations

Calculations are the metadata for an enabled FINCAD function. Calculations specify the FINCAD function, the input parameters expected by the function at start of execution, and the database table locations to store calculation outputs. You can selectively override output parameters to control how you store results in the PACE data warehouse. You can use the same calculation for more than one calculation rule.

Calculation Rules

The calculation rule defines the types of securities and entities to use with each associated calculation. The rule lists the calculations to invoke, including overrides to input parameters for default calculations. Rules are schedulable events. You can also submit a rule for processing on an ad hoc basis.

Functions

Functions reside in the FINCAD library of functions. There is a one-to-one relationship between a calculation and a FINCAD function. Each function uses a proprietary set of input and output parameters, configurable within the associated calculation rule.

Input Parameters

Input parameters define the data sent to the calculation. They are based on field attributes, codes, and code translations. You can customize the calculation to override input parameters, to suit sourcing requirements.

Output Parameters

Output parameters define the database locations used to commit the data generated from analytics calculations. You can customize the calculation rule to override outputs, to suit database update requirements.

Enable FINCAD Functions

You must enable FINCAD functions before you can use the function within the Reference Data Center for Eagle Analytics. You can enable a set of FINCAD functions by importing an initial migration package file (*.pkg) with the associated calculations and input/output parameter definitions. Importing the functions also imports a set of calculations that have the same name as the associated underlying FINCAD function. Once you enable the functions, you can manage calculations to suit changing business requirements.

About the Initial Migration Package

Most functions are not yet enabled for use by the Eagle rules engines. Eagle provides an initial migration package file that you can use to set up your first set of FINCAD functions and associated calculations, including many standard analytics calculations. You can request additional setups for other FINCAD functions by contacting Eagle's Global Professional Services and Instrument Engineering teams. Contact your Eagle Relationship Manager (RM) or Eagle Client Operations (COM) for more information.
 

Manage Eagle Analytics Functions

You can view and copy the imported FINCAD analytics functions. You can also view, edit, and delete any copied analytics functions.

View / Edit an Analytics Function

You can view and edit Eagle Analytics functions, including the calculation name, description, and the FINCAD analytics function used. You can override input arguments used with these calculations and output arguments assigned to calculation results. Eagle recommends that you do not apply changes directly to the original analytics functions and edit only copies of these functions, to preserve the integrity of the Eagle Analytics migration package.

Manage Calculations

You can manage the Eagle Analytics calculations used by the standard FINCAD functions for option-adjusted spread, duration, and convexity analytics, as well as the functions for duration, mod duration, convexity, mod convexity, and basis point value computations. You can view/edit, create, duplicate, and delete calculations.
NOTE: Calculations are initialized with imported Eagle package files and conventionally use the same naming convention as the underlying FINCAD function. The best practice is to duplicate an imported calculation and then apply any customizations to the copied calculation.
