Data Modeling is the process of developing a data model for storing data in a database. It conceptually represents data objects, data object associations, business rules, regulatory compliances, and government policies on the data. Data Models ensure consistency in naming conventions, default values, semantics, security, and data quality.
Data Modeling in SQL Server Management Studio is frequently created using sophisticated tools such as ER/Studio or ERWIN. But these are not required. You will see how to create data model in SQL in other ways in the blog. We’ll also cover the details of Data Modeling in SQL Server Management Studio (SSMS) and leave you with no doubts regarding this concept!

What is Data Modeling in SQL?
Data Modeling is the practice of evaluating data objects and their relationships to other things. It is used to investigate the data requirements for business processes. The Data Models are intended to be used to store data in a database. The Data Model focuses on what data is needed and how data is organized, rather than what actions must be taken.
A Data Model is similar to a blueprint for a building designed by an architect. It is a method of documenting complex software system designs in the form of a simple graphic. The diagram will be created using text and symbols to describe how the data will flow. It is frequently referred to as a blueprint for creating new software or reengineering existing applications.
Key Features of Data Modeling
Here are some characteristics of Data Modeling:
- Savings on Costs: Data Models enable you to create apps at a lower cost. Data modeling typically consumes less than 10% of a project’s budget and has the potential to reduce the 70% of the budget typically allocated to programming.
- Broader Horizons: A Data Model is a focal point for determining scope. It offers something practical to assist corporate sponsors and developers in reaching an agreement on what is and is not included with the product.
- Documentation has been Improved: By documenting fundamental concepts and language, models serve as a foundation for long-term maintenance. Even if your staff changes, the documentation will be useful to you.
- Management of Risk: A Data Model can be used to quantify software complexity and gain insight into project risk and development effort.
- A Good Place to Begin with Data Mining: The documentation for a model serves as a starting point for analytical data mining. Daily company data can be loaded into a dedicated database known as a “Data Warehouse.”
- Reduced Time to Market: You can also build software faster by detecting errors early on. A Data Model can also be used to automate some processes.
What is SQL Server Management Studio?
SQL Server Management Studio (SSMS) is a software application that was introduced with Microsoft SQL Server 2005 and is used to configure, manage, and administer all components of Microsoft SQL Server. It is the replacement for the Enterprise Manager in SQL 2000 or earlier.
SSMS is one of the SQL Server management tools used for designing queries and managing databases and data warehouses via personal computer or cloud, regardless of your location. In reality, SSMS is a unified environment that includes tools for configuring, monitoring, and managing SQL Server instances and databases.
The Object Explorer is a key feature of SSMS, allowing the user to browse, select, and act on any object on the server. It also included a free Express edition, but recent versions of SSMS are fully capable of connecting to and managing any SQL Server Express instance. Microsoft also included backward compatibility for older SQL Server versions, allowing a newer version of SSMS to connect to older SQL Server instances.
Key Features of SQL Server Management Studio
Features of SQL Server Management Studio are as follows:
- Polybase: Polybase is included as part of the SQL module in SQL Server, allowing users to run fast and parallel T-SQL queries and even connect to external storage.
- Data Recoverability: SQL Server supports ADR (Accelerated Data Recovery), a novel technique for recovering a database in the event of a system or transaction rollback.
- Construction of a Resumable Index: SQL Server has the ability to pause index construction and resume it later.
- Support for Cloud Databases: Microsoft SQL Server has editions with built-in security and manageability that can be integrated with Microsoft cloud or Azure SQL.
- Complete Business Data Solutions: SQL Server is primarily intended for commercial use, and it provides end-to-end business data solutions. Microsoft SQL Server includes tools for Data Administration, ETL solutions, Online Analytical Processing (OLAP), and Data Mining.

How Data Modeling in SQL Server Management Studio is Carried?
This blog will demonstrate Data Modeling in SQL Server Management Studio and create a simple Data Model of a limited number of tables in the database using Microsoft’s SQL Server Data Modeling WideWorldImporters.
The steps for Data Modeling in SQL Server Management Studio are as follows:
Step 1: Create a new SQL Server Management Studio Data Model
Right-click “Database Diagrams” under the database WideWorldImporters in SSMS and select “New Database Diagram.”
Step 2: From the Data Model, Choose a table
Scroll down and select the Invoice table from the Database Diagrams tool dialogue. Add is followed by Close.
Step 3: Add Related Tables from the Data Model
Select “Add Related Tables” from the context menu of the Invoices table. This adds tables that are linked to the Invoices table via Foreign Keys, of which the Invoices table is a foreign key.
Step 4: Remove any unnecessary tables from the Model
Right-click on any table that you believe is unnecessary and will clog the diagram and select “Remove From Diagram.”
Step 5: Auto Arrange Tables from the Data Model
Select “Arrange Tables” from the menu that appears when you right-click the Invoices table. This keeps the tables from overlapping.
The ideology behind creating a manual Data Pipeline is one that requires a lot of time, effort, and understanding. Automated tools like Hevo can automate this process without writing a single piece of code.

Step 6: From the Data Model, Adjust the Layout
You have the option for Data Modeling in SQL Server Management Studio, following are:
- To see your tables, right-click and choose a Zoom level.
- Drag a table to change its position.
- To resize the table layout, click a table and move the cursor to the edge.
Step 7: From the Data Model, select Auto Size All Tables
To select all tables, press CTRL + A. Select “Autosize Selected Tables” by right-clicking any highlighted table. To rearrange the connector lines, select and drag them.
Step 8: Copy to Clipboard from the Data Model
Once the Diagram has been sized and arranged to your liking, click Save and give it a name for the SQL Server Data Modeling. Then, on any white space in the Diagram, right-click and select “Copy Diagram to Clipboard.“
Step 9: Copy and Paste the model into Microsoft Word
Launch Microsoft Word. Insert a single-cell table and paste it into the SQL Server Data Modeling.
Step 10: Adjust and Maximize the image of the Data Model
Optimize the database diagram image in the Word document. Change the margins to 0.5 inches, then upload the image and resize it to enlarge it. A database diagram from a Word document is shown below.
Limitations of Data Modeling in SQL Server Management Studio
Even those with access to similar solutions who work with Microsoft SQL Server use SQL Server’s Management Studio (SSMS). SSMS is well-known among database professionals, and it is a useful tool. It does, however, Data Modeling in SQL Server Management Studio has limitations, they are:
- Performance Monitoring: Data Modeling in SQL Server Management Studio displays Availability and Performance metrics but is insufficient for Comprehensive Performance Management.
- Regulatory Compliance: Data Modeling in SQL Server Management Studio can give Views and Manage User Activity, but User Access to Databases is not suitable for Extensive Auditing
- Security Monitoring: Data Modeling in SQL Server Management Studio displays User Activity and Manages User Access to Databases, but is insufficient for State Security Management.
- Inventory Management: Data Modeling in SQL Server Management Studio Automatically discovers instances and provides basic Instance Management but is not suitable for Extensive Inventory Management
- Backup Management: Data Modeling in SQL Server Management Studio can help you Start and Stop backups and restores, as well as display backup settings and status; however, it is not suitable for Extensive Backup and Restore Management.
This is an efficient method for creating a simple, limited option for Data Modeling in SQL Server Management Studio. A good way to document a Database is to create partial Data Models around logical groups of tables.
Other options for SQL Server Data Modeling include only displaying the Table Names and Relationships or only displaying the Key Columns, which may allow for more tables to be added to the Data Model while still fitting in a Word document.
