Examples of design decisions may include: Queries or other inputs the database will accept and outputs displays, reports, messages, responses, etc. Database behavior in response to each input or query, including actions, response times and other performance characteristics. Type of flexibility to be built into the database for adapting to changing requirements. Levels and types of availability, security, privacy, and continuity of operations. Decisions on sorting, indexing, synchronization, and consistency including automated disk management, optimizing strategies, storage and size considerations, and population of the database and capture of legacy data.

Instructions for generating, modifying, updating, or otherwise using the database. Standards Deviations List any known deviations from corporate standards and recommended guidelines. Entity Mapping Identify the mapping rules and lists tables and columns that either: Do not originate from a single entity Are not implemented.

Mapping rules Entities are mapped onto tables in a one to one manner Attributes are mapped to columns in a one to one manner One-to-many relationships are mapped to foreign keys Many-to-many relationships are implemented using a keys-only table. Lists database objects tables or columns that were not derived from an entity but added to the database design for the purpose listed below.

Identify the tables that have primary keys created from sequences: Database Design Document Template Version 1. Identify deviations from a one-to-one mapping of entity and attribute names to table and column names and any foreign key naming deviations.

Denormalisation Where appropriate, describe how redundancy is added to the design to improve performance or support specific functionality. Performance Improvement Identify objects that were modified in order to improve performance:.

Functional Support Identify objects that were modified in order to support the proposed functionality of [Application]:. Storage Provide sizing formulas for determining the storage required to support the database. Estimate the internal and peripheral storage requirements. Recovery Describe how data, schemas and support files will be recreated or recovered in the event of a system disaster.

Database Interfaces 5. Database Interfaces Describe interfaces with other applications including those of other operational capabilities. Operational Implications Describe operational implications of data transfer, including security considerations.

Details Describe the purpose of the interface Summarize the interface characteristics Describe the interface architecture. Describe the API and error conditions. Reference separate module interface specifications for more detailed information.

Describe protocols, user authentication, encryption, access control at the interface entry point. Dependencies List any dependencies for the [Application] schema, for example, foreign keys across schemas.

Design issues Describe the design to support reporting and other information requirements. Data Access Discuss which roles are needed to use the database and highlight any significant information related to the physical database implementation, for example, tables subject to high insert or delete activity or with specific archiving rules. Users Identify users that will be recognized by the database, including estimates of user volumetrics.

Table Access Patterns Identify performance-critical functions and their table usage. Where possible, provide volumetric information needed for the physical database design. Implementation Considerations 8.

Queues Describe how queues i. Specify which functionality the queue implements and the implementing queuing technology e. Security Design Describe authentication, integrity, and confidentiality requirements that will be supported within the database.
