Conceptually modeling windows and bounds for space and time in database constraints

GIS, logistics, CAD/CAM, robotics, and medical imaging systems uses spatial data, while systems for financial services, inventory management, professional sports, consumer research, and payroll uses historical or temporal data. A Customer Relationship Management (CRM) application can track and keep information about customers and promotions. Some of the significant advantages during modeling constraint semantics for conceptual design are reduced cost of correcting errors, consistent application enforcement, and improved ability to validate requirements with users. The modeling constraints for conceptual design can provide accurate representation of semantics. The model-driven architecture (MDA) method can automate the translation of constraints into database.
