Part 7: Data Architecture, Consistency, and Information Lifecycle Management |
111. Data as the Central Asset of ERP Systems |
111.1 |
At its core, an ERP system is a data management system that happens to implement business logic. |
111.2 |
Processes, workflows, reports, and decisions all depend on the accuracy, consistency, and availability of enterprise data. |
111.3 |
Modular ERP architecture exists primarily to manage data complexity in large organizations. |
|
112. Centralized Data Architecture in Modular ERP Systems |
112.1 |
Most ERP systems employ a centralized data architecture. |
112.2 |
All modules interact with a shared enterprise database or logically unified data store. |
112.3 |
This ensures a single authoritative record for each business entity. |
112.4 |
Centralization eliminates reconciliation and synchronization problems common in fragmented systems. |
|
113. Logical Versus Physical Data Centralization |
113.1 |
It is important to distinguish logical centralization from physical centralization. |
113.2 |
Logical centralization refers to unified data definitions and governance. |
113.3 |
Physical centralization refers to storage location. |
113.4 |
Modular ERP systems may physically distribute data while maintaining logical unity. |
|
114. Data Ownership Within Modular Boundaries |
114.1 |
Each module owns specific data domains. |
114.2 |
Ownership implies responsibility for validation, lifecycle rules, and integrity. |
114.3 |
Other modules may reference this data but cannot redefine it. |
114.4 |
Clear ownership prevents ambiguity and corruption. |
|
115. Master Data, Transaction Data, and Reference Data |
115.1 |
ERP data is commonly categorized into master data, transaction data, and reference data. |
115.2 |
Master data defines long-lived entities such as products, customers, and suppliers. |
115.3 |
Transaction data records business events. |
115.4 |
Reference data provides controlled vocabularies and codes. |
|
116. Lifecycle Management of Master Data |
116.1 |
Master data follows a defined lifecycle. |
116.2 |
This includes creation, validation, activation, modification, and deactivation. |
116.3 |
Modular ERP architecture enforces lifecycle rules at the owning module. |
116.4 |
This ensures consistent behavior across the system. |
|
117. Transaction Data Integrity and Atomicity |
117.1 |
Transaction data must be accurate and complete. |
117.2 |
ERP systems enforce atomic transactions to prevent partial updates. |
117.3 |
Modular architecture defines transaction boundaries clearly. |
117.4 |
This ensures reliable business records. |
|
118. Historical Data and Temporal Accuracy |
118.1 |
ERP systems must preserve historical accuracy. |
118.2 |
Data changes should not retroactively alter historical records. |
118.3 |
Modular architecture supports temporal data management. |
118.4 |
This is critical for audits, reporting, and compliance. |
|
119. Consistency Models in Modular ERP Systems |
119.1 |
Consistency is a core data concern. |
119.2 |
ERP systems balance strict consistency with performance. |
119.3 |
Some data requires immediate consistency, while other data allows eventual consistency. |
119.4 |
Modular architecture defines consistency requirements per domain. |
|
120. Referential Integrity Across Modules |
120.1 |
Referential integrity ensures valid relationships between entities. |
120.2 |
ERP systems enforce referential integrity at both database and application levels. |
120.3 |
Modules respect ownership boundaries when referencing data. |
120.4 |
This preserves data trustworthiness. |
|
121. Data Validation and Business Semantics |
121.1 |
Data validation is more than type checking. |
121.2 |
ERP systems validate data against business semantics. |
121.3 |
Each module enforces rules relevant to its domain. |
121.4 |
This prevents meaningless or invalid records. |
|
122. Redundancy Avoidance Through Shared Data Models |
122.1 |
Redundant data creates inconsistency. |
122.2 |
Modular ERP architecture minimizes redundancy. |
122.3 |
Shared entities are defined once and reused. |
122.4 |
This reduces maintenance and error risk. |
123. Data Extension Without Duplication |
123.1 |
Modules may require additional attributes for shared entities. |
123.2 |
Modular architecture supports extensions without duplication. |
123.3 |
Extended attributes are linked, not copied. |
123.4 |
This preserves integrity while enabling flexibility. |
|
124. Data Access Control and Privacy |
124.1 |
Not all data should be visible to all users. |
124.2 |
ERP systems enforce access control at the data level. |
124.3 |
Modular architecture supports domain-specific privacy rules. |
124.4 |
This is essential for legal and ethical compliance. |
|
125. Data Quality Management |
125.1 |
Data quality is a continuous concern. |
125.2 |
ERP systems implement validation, monitoring, and correction mechanisms. |
125.3 |
Modules are responsible for data quality in their domains. |
125.4 |
This distributed responsibility improves overall quality. |
|
126. Archiving and Data Retention Policies |
126.1 |
ERP systems accumulate vast amounts of data. |
126.2 |
Retention policies govern how long data is kept. |
126.3 |
Modular architecture supports selective archiving. |
126.4 |
This balances compliance and performance. |
|
127. Data Migration and System Evolution |
127.1 |
ERP systems evolve through upgrades and reconfiguration. |
127.2 |
Data migration must preserve integrity. |
127.3 |
Modular architecture simplifies migration by isolating domains. |
127.4 |
This reduces risk during change. |
|
128. Reporting Data Versus Operational Data |
128.1 |
Operational data supports daily transactions. |
128.2 |
Reporting data supports analysis and decision-making. |
128.3 |
Modular ERP architecture supports separation of concerns. |
128.4 |
This improves performance and accuracy. |
|
129. Analytical Consistency Across Modules |
129.1 |
Enterprise analytics rely on consistent data definitions. |
129.2 |
Modular architecture enforces standardized measures. |
129.3 |
This ensures comparable metrics across domains. |
129.4 |
Reliable analytics support strategic decisions. |
|
