Data Conversion Workflow

Step 1:Requirements &

Planning

Decide destination file format

Decide the destination storage requirements

Step 2:Design Functions for

Data Conversion Process

Data Conversion Process:Data Requirement/Documentation

Functions or methods:- Names - Definitions with formal input/output parameters- Documentation

Step 3: Load, Monitor, and

Audit Data Conversion Data Conversion Process:

- Data Conversion Report- Data conversion logs- Problems and Records

Step 4:Perform Data Movement,

Conversion, and Store

Workflow for Data Conversion

Database

Inventory of current data files

Locate sources of data files

Determine current date file format

Design communication functions

Design data movement functions

Design data conversion functions

Design human interface functions

Technical staff assignment

Process Loading, Monitoring

Start, Stop, Verify Data Conversion Process

Process Administration

Move data files to temporary storag

Convert Data Files

Re-order, and/or Merge Data Files

Verify and Store Data Files

Other Data SourcesFiles

Data Modeling Workflow – for Database Design & Application

Step 1:Requirement

Analysis

Application data requirements

Possible data and service reuse by other applications

Data efficiency and cost

Step 2:Conceptual

Data Modeling

Current business process and existing data structrures

Data ownership

Data dependency

Classify entities and attributes

Define relationships

Identify relevant data to be stored in the database

Application Data Requirement/Documentation

Data Requirement/Data objects, entities, Attributes, relationships, constraints

Entity-Relationship Model/ Diagrams

Step 3: Logical

Data Modeling

DB Schemas/Primary keys, foreign keys,views

Relational Model/Table

Step 4:Schema

Refinement

Convert entity set to relational tables

Analyze the collection of relations

Identify potential problems

Normalizing relations

How can data be manipulated and queried

How can data be created and modified

Integrity constraints

Specifying key constraints

Workflow for Data Modeling

Step 1. Requirement Analysis • Inputs:

o Current business process & existing data structures o Application data requirements o Data ownership o Data dependency o Data efficiency and cost o Possible data and service reuse by other applications

• Outputs: o Application data requirement o Documentation

Step 2. Conceptual Data Modeling • Inputs:

o Classify entities and attributes o Defines relationships o Identify relevant data to be stored in the database

• Outputs: o Entity-Relationship Models/Diagrams o Data Requirements

Data objects, entities, attributes, relationships, constraints Step 3. Logical Data Modeling

• Inputs: o Convert entity set to relation tables o How can data be created and modified o How can data be manipulated and queried o Integrity constraints o Specifying key constraints

• Outputs: o Relational Model/Table o DB Schema/Primary keys, foreign keys, views

Step 4. Schema Refinements • Inputs:

o Analyze the collection of relations o Identify potential problems o Normalizing relations

• Outputs

11

Logical Data Structure (LDS) • Vocabulary of LDS

o Entity o Attribute o Relationship: one-to-one, one-to-many, many-to-one, many-to-many o Link o Descriptor o Maximum degree o Identifier

• Entity o Represented by a box o Examples – a COW entity with 5 attributes

COW for RFID Tracking • Cow ID • Name • Birth Place • Birth Weight • Current Weight

o Instances
