Super GAC for Complete Email Archive Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional message management systems face difficulties in searching email archives due to changes in the global address catalog (GAC), such as deletions, modifications, and reusages of email addresses, which can lead to incomplete retrieval of associated emails.
Innovation Solution
A super GAC is created and maintained separately, incorporating additional information from external sources like human resource records and payroll data, with time-bound associations to preserve deleted or modified identities, allowing searches based on display names, email addresses, and other attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system uses the conventional GAC to search email archives, then the search operation is simple and fast, but the search results become incomplete when email addresses are deleted, modified, or reused in the GAC
Solution Approach 1:
The patent implements a hierarchical structure where the super GAC contains and encompasses the conventional GAC. The super GAC is a nested catalog that includes all entries from the conventional GAC plus additional historical entries for deleted and modified email addresses. This nesting allows the system to maintain the simple conventional GAC for current operations while embedding the comprehensive historical data structure within it, enabling complete email retrieval without requiring system-wide architectural overhaul.
Solution Approach 2:
The system performs preliminary actions by proactively creating and maintaining the super GAC before search operations are needed. The super GAC is pre-populated with historical email address data, deletion records, and modification histories in advance. When a search is executed, the system can directly query this pre-prepared comprehensive catalog without needing to perform complex real-time analysis of email address lifecycle changes, thus ensuring complete retrieval while keeping the search operation itself simple and fast.
2Loss of information
If the system maintains only current GAC entries, then the system is simple to manage, but it cannot retrieve emails associated with historical or deleted identities
Solution Approach 1:
The patent creates a copy of the conventional GAC structure to form the super GAC. Instead of modifying the existing simple GAC system, the invention makes a副本 (copy) that replicates the current GAC entries and adds historical data to this copy. The super GAC serves as a comprehensive duplicate catalog that preserves all historical email address information including deleted and modified entries, while the original conventional GAC remains unchanged for ongoing operations. This copying approach allows historical information preservation without significantly complicating the primary GAC maintenance procedures.
3Adaptability or versatility
If email addresses are reused after deletion in the GAC, then the GAC remains dynamic and adaptable, but search operations cannot associate new emails with old identity histories
Solution Approach 1:
The patent implements a dynamic tracking system within the super GAC that monitors the lifecycle of email addresses over time. Each email address entry in the super GAC contains temporal information and versioning data that records when addresses were created, deleted, modified, and reused. This dynamic structure allows the system to maintain adaptability for email address reuse while simultaneously preserving the historical context needed for accurate identity-email association. The super GAC dynamically updates to reflect current GAC flexibility while maintaining precision through its comprehensive historical record-keeping capabilities.
Data Source
AI summary
A method and apparatus for creating a catalog for use with at least one computer system that manages a plurality of email messages. The catalog provides an index into the plurality of email messages, and comprises a plurality of identifiers that each identifies an entity. The catalog also correlates at least some of the plurality of identifiers to corresponding email addresses. The method for creating a catalog comprises creating the catalog to include information defining a temporal interval during which at least one email address corresponds to a first entity.
