| Declarative Constraint Engine Features |
| Declarative Form |
Business logic expressed in declarative, not procedural, form. Business entities are represented using parameters. Relationships between parameters are captured as constraints. |
| Scalable |
Declarative form compact compared to procedural engine. Inherently scalable for faster throughput. |
| High Performance |
State-based engine considers only changes to model, instead of processing entire model, for significantly faster processing. |
| Simplified Architecture |
No elaborate procedures are required to get valid configuration. |
| Automated |
Engine automatically adjusts to added or removed parameter or constraint. Runs all applicable constraints and rejects choice in case of constraint failure. State of business model always correct. |
| Selectica Pricer |
Manage pricing data including list prices, discounts, and promotions across various channels, regions, customer types, and products using real-time pricing information. |
| Knowledge Base Features |
 Dual Core Enabled |
Take advantage of dual-core processors by enabling parallel loading of knowledge bases, reducing load time to almost half. |
| Repository |
Repository includes business entities and logic. |
| Parameters |
Parameters (business entities to be configured) can be logical, cumulative, or programmatic. |
| Constraints |
Constraints (relationships between business entities) can be hard or soft, and can consist of algebraic expressions, function expressions, rules, tables, compatibility/ incompatibility, or resource. |
| Components |
Components (pre-defined business objects, which are the parts and their attributes) can be hierarchical and can be loaded from a database. |
| Modeling Features |
| Dynamic Properties |
Dynamic component properties simplifies modeling because it permits descriptive attributes to be attached to a component, such as price, PC board slot number, and quantity. |
| Complexity |
Rich modeling constructs permit modeling at attribute and meta level, instead of component level, easing modeling of complex products and services. |
| Object-Oriented |
Supports inheritance to extract common behavior and data. Also supports composition that can reflect physical containment. |
| Parameters |
Multiple types of parameters are available, including referential parameters, resource parameters, and containers of parameters. |
| Validity Dates |
Validity dates available for models, parameters, constraints, and components. |
| Extensible |
Model is extensible to allow user-defined functions. |
| Runtime Features |
| Resource Calculation |
Automatic resource calculations during runtime ensure that resource requirements are met. For example, the system can automatically calculate the total power requirements for a PC system configuration, and indicate if the selected PC power supply will be adequate. |
| Ajax Enablement |
Performance improvement by communicating only changes to configuration, instead of entire model, enabling Ajax operation on user interface.
|
| Rollbacks |
Supports multiple rollback points for What-If Analysis, such as comparing multiple configurations. |
| Load Time Reduction |
Up to 40% faster knowledge base load time improvement. |
| Runtime Performance |
Up to 20% faster runtime performance. |
| RAM Reduction |
Up to 40% decrease in RAM memory size requirement for knowledge base and up to 30% decrease for session memory requirement. |
| Dual Core Enabled |
Take advantage of newer dual-core (and quad-core) processors by enabling multi-threading during runtime, improving performance by over 30%. For organizations using Virtualization, performance can also be dramatically improved by allocating multiple processors to Selectica configurations. |
| Scalable |
Shares model across knowledge base. Architecture inherently scalable. |
| Data Driven |
Database connectivity at various levels, including design-time, load-time, and run-time. |
| Solution Configuration |
Supports solution configuration, where multiple “independent” sub-configurations can be started, then placed in a parent configuration. |
| Dynamic Modeling |
Supports dynamic modeling, including run-time sub-classing. |
| Partial Configurations |
Supports saving of partial configurations. |
| Failure Messages |
Supports multiple failure message scenarios, including internationalization of messages , as well as custom error messages. |
| Warnings |
Supports messages that indicate violation of soft constraints. |
| Analytics Features |
| Knowledge Base |
Generates knowledge base analytics, such as number of constraints, parameters, and relationships. |
