Introduction

An entity is any element in the Quintessence database that has data associated with it and is identified by a code, for example, instruments, portfolios, countries or managers. Some entities are associated with TimeSeries data, in other words a series of values at different points in time. Some entities are linked to constituents via a Relationship and as part of that relationship have associated RelationshipData.

Entity code types

Entity codes are created by data providers, authors and users to represent an entity and differentiate it from other entities within a system. The code only needs to be unique within its own system. Because there are multiple systems an entity frequently has multiple codes. Each of these codes is a valid form of identification for that entity.

When an entity might not have a unique code (the code means different things in different systems), the intended entity can be located by Quintessence in two ways:

1. By qualifying the code with a code type, for example: AB05:StockExchange1 Alpha Code
2. If a code type is not provided, Quintessence uses the code type precedence as set up by the system administrator. The system selects the code type with the highest precedence, and locates the entity accordingly.

Examples of code types:

In Quintessence, all codes and code types for an entity are linked to that entity. When looking up an entity code in the Quintessence Entity Browser, any alternative code types and codes for that entity are listed:
