Overview

Data model is a conceptual representation of data structures(tables) required for a database and is very powerful in expressing and communicating the business requirements.

A data model visually represents the nature of data, business rules governing the data, and how it will be organized in the database. A data model is comprised of two parts logical design and physical design.

Data model helps functional and technical team in designing the database. Functional team normally refers to one or more Business Analysts, Business Managers, Smart Management Experts, End Users etc., and Technical teams refers to one or more programmers, DBAs etc. Data modelers are responsible for designing the data model and they communicate with functional team to get the business requirements and technical teams to implement the database.

Data Modeling Tools

There are a number of data modeling tools to transform business requirements into logical data model, and logical data model to physical data model. From physical data model, these tools can be instructed to generate sql code for creating database.

Tools:What to Learn?

Data modeling tools are the only way through which we can create powerful data models. Following are the various options that we have to know and learn in data modeling tools before start building data models

DM Tools - Erwin

All Fusion Erwin Data Modeler commonly known as Erwin , is a powerful and leading data modeling tool from Computer Associates. Computer Associates delivers several softwares for enterprise management, storage management solutions, security solutions, application life cycle management, data management and business intelligence.

DM Tools - Xcase

Xcase is a powerful and intuitive data modeling tool. It automates database creation and maintenance, making the modeling process simple and visual. The tool provides tight support for the leading DBMS and an impressive set of capabilities.

Using Xcase, data modelers can create data models from scratch or from existing databases using the Reverse Engineering module. Once the model is complete, XcaseForward Engineering module generates all the DDL scripts necessary to create a new database or update an existing one.

Development Cycle

Gathering Business Requirements - First Phase

Data Modelers have to interact with business analysts to get the functional requirements and with end users to find out the reporting needs.

Conceptual Data Modeling(CDM) - Second Phase

This data model includes all major entities, relationships and it will not contain much detail about attributes and is often used in the INITIAL PLANNING PHASE.

Logical Data Modeling(LDM) - Third Phase

This is the actual implementation of a conceptual model in a logical data model. A logical data model is the version of the model that represents all of the business requirements of an organization.

DM Standards

Standardization Needs | Modeling data

Several data modelers may work on the different subject areas of a data model and all data modelers should use the same naming convention, writing definitions and business rules.

Nowadays, business to business transactions(B2B) are quite common, and standardization helps in understanding the business in a better way. Inconsistency across column names and definition would create a chaos across the business.

For example, when a data warehouse is designed, it may get data from several source systems and each source may have its own names, data types etc. These anomalies can be eliminated if a proper standardization is maintained across the organization.

Table Names Standardization:

Giving a full name to the tables, will give an idea about data what it is about. Generally, do not abbreviate the table names; however this may differ according to organization's standards. If the table name's length exceeds the database standards, then try to abbreviate the table names. Some general guidelines are listed below that may be used as a prefix or suffix for the table.

Create a Data Model

These are the general guidelines to create a standard data model and in real time, a data model may not be created in the same sequential manner as shown below. Based on the enterprise's requirements, some of the steps may be excluded or included in addition to these.

Data Modeler Role

Business Requirement Analysis:

Interact with Business Analysts to get the functional requirements.

Interact with end users and find out the reporting needs.

Conduct interviews, brain storming discussions with project team to get additional requirements

Gather accurate data by data analysis and functional analysis.

Modeling Reports

From Data Modeling tools, reports can be easily generated for technical and business needs. The reports that have been generated from logical data model and physical data model are called as business reports and technical reports respectively. Most of the data modeling tools provide default reports like subject area reports, entity reports, attribute reports, table reports, column reports, indexing reports, relationship reports etc. The advantage of these reports is, whether they are technical or non-technical, everybody would understand what is going on within the organization.

Conceptual DM

Conceptual data model includes all major entities and relationships and does not contain much detailed level of information about attributes and is often used in the INITIAL PLANNING PHASE.

Enterprise DM

The development of a common consistent view and understanding of data elements and their relationships across the enterprise is referred to as Enterprise Data Modeling. This type of data modeling provides access to information scattered throughout an enterprise under the control of different divisions or departments with different databases and data models.

Logical DM

This is the actual implementation and extension of a conceptual data model. A Logical data model is the version of a data model that represents the business requirements(entire or part) of an organization and is developed before the physical data model.

Physical DM

Physical data model includes all required tables, columns, relationships, database properties for the physical implementation of databases. Database performance, indexing strategy, physical storage and denormalization are important parameters of a physical model.

Logical vs Physical

When a data modeler works with the client, his title may be a logical data modeler or a physical data modeler or combination of both. A logical data modeler designs the data model to suit business requirements, creates and maintains the lookup data, compares the versions of data model, maintains change log, generate reports from data model and whereas a physical data modeler has to know about the source and target databases properties.

A physical data modeler should know the technical-know-how to create data models from existing databases and to tune the data models with referential integrity, alternate keys, indexes and how to match indexes to SQL code. It would be good if the physical data modeler knows about replication, clustering and so on.

Relational(OLTP) DM

Relational Data Model is a data model that views the real world as entities and relationships. Entities are concepts, real or abstract about which information is collected. Entities are associated with each other by relationship and attributes are properties of entities. Business rules would determine the relationship between each of entities in a data model.v

Dimensional DM

Dimensional Data Modeling comprises of one or more dimension tables and fact tables. Good examples of dimensions are location, product, time, promotion, organization etc. Dimension tables store records related to that particular dimension and no facts(measures) are stored in these tables. For example, Product dimension table will store information about products(Product Category, Product Sub Category, Product and Product Features) and location dimension table will store information about location( country, state, county, city, zip. A fact(measure) table contains measures(sales gross value, total units sold) and dimension columns. These dimension columns are actually foreign keys from the respective dimension tables.

Relational vs Dimensional

Relational Data Modeling is used in OLTP systems which are transaction oriented and Dimensional Data Modeling is used in OLAP systems which are analytical based. In a data warehouse environment, staging area is designed on OLTP concepts, since data has to be normalized, cleansed and profiled before loaded into a data warehouse or data mart. In OLTP environment, lookups are stored as independent tables in detail whereas these independent tables are merged as a single dimension in an OLAP environment like data warehouse.

Dimensions

Dimension Table

Dimension table is one that describe the business entities of an enterprise, represented as hierarchical, categorical information such as time, departments, locations, and products. Dimension tables are sometimes called lookup or reference tables.

Location Dimension

In a relational data modeling, for normalization purposes, country lookup, state lookup, county lookup, and city lookups are not merged as a single table. In a dimensional data modeling(star schema), these tables would be merged as a single table called LOCATION DIMENSION for performance and slicing data requirements. This location dimension helps to compare the sales in one region with another region. We may see good sales profit in one region and loss in another region. If it is a loss, the reasons for that may be a new competitor in that area, or failure of our marketing strategy etc.

Slowly Changing Dimensions

Dimensions that change over time are called Slowly Changing Dimensions. For instance, a product price changes over time; People change their names for some reason; Country and State names may change over time. These are a few examples of Slowly Changing Dimensions since some changes are happening to them over a period of time.

Slowly Changing Dimensions are often categorized into three types namely Type1 , Type2 and Type3 . The following section deals with how to capture and handling these changes over time.

The "Product" table mentioned below contains a product named, Product1 with Product ID being the primary key. In the year 2004, the price of Product1 was $150 and over the time, Product1's price changes from $150 to $350. With this information, let us explain the three types of Slowly Changing Dimensions. be457b7860
