Database Programming in VB.NET

Database-programming is an essential part of modern software development, especially when it comes to creating enterprise-level applications. VB.NET, a popular programming language developed by Microsoft, offers a robust set of features for working with databases. In this article, we will dive into the world of database programming in VB.NET, exploring what it is, why it is important, and how to get started.


Before we dive into the specifics of database-programming in VB.NET, let’s take a moment to understand what database-programming is and why it is important. In simple terms, database-programming involves creating software applications that interact with a database. The goal of database-programming is to create applications that can store, retrieve, update, and delete data in a database.

Understanding Databases

A database is an organized collection of data, typically stored and accessed electronically. Databases are used to store a wide range of information, from simple text to complex multimedia files. There are different types of databases, but the most common types are relational and non-relational databases.

Types of Databases

Relational databases store data in tables that are related to each other using key fields. Non-relational databases, on the other hand, store data in a variety of formats such as documents, graphs, and key-value pairs.

Relational Database Management Systems (RDBMS)

Relational Database Management Systems (RDBMS) are software systems that are used to manage relational databases. The most popular RDBMS systems are Oracle, MySQL, and Microsoft SQL Server.

Non-Relational Databases

Non-relational databases are used to store data that does not fit into a traditional table structure. Examples of non-relational databases include MongoDB and Cassandra.

Understanding MSSQL

What is MSSQL?

MSSQL is a powerful and reliable RDBMS designed for enterprise-level applications. It is widely used for managing large amounts of data, including financial transactions, customer information, inventory management, and more. MSSQL provides a scalable and secure platform for storing and retrieving data, with built-in support for data backup and recovery, high availability, and disaster recovery.

Features of MSSQL

MSSQL offers a range of features that make it an ideal choice for enterprise-level applications. Some of the key features of MSSQL include:

  • Relational database management:  MSSQL is a relational database management system that supports SQL queries, transactions, and indexing.
  • Scalability:  MSSQL can scale from a small single-server deployment to a large, distributed system with high availability and fault tolerance.
  • Security:  MSSQL provides robust security features, including encryption, authentication, and authorization.
  • Performance: MSSQL is optimized for high-performance data processing, with features like in-memory tables, columnstore indexes, and query optimization.
  • Integration: MSSQL integrates seamlessly with other Microsoft products like Excel, Access, and SharePoint.

Using MSSQL and VB.NET Together

MSSQL and VB.NET can be used together to build robust, scalable applications that can handle large amounts of data. VB.NET provides a powerful and easy-to-learn language for developing Windows-based applications, while MSSQL provides a robust and scalable database platform for storing and retrieving data. Together, these technologies can be used to build a wide range of applications, including:

  1. Financial applications: MSSQL can be used to store financial data, while VB.NET can be used to build a user-friendly interface for managing the data.
  2. Inventory management systems: MSSQL can be used to store inventory data, while VB.NET can be used to build a user-friendly interface for managing inventory.
  3. Customer relationship management (CRM) systems:  MSSQL can be used to store customer data, while VB.NET can be used to build a user-friendly interface for managing customer relationships.

Key Points in Database-Programing

Connecting to a Database

Before we can start working with a database in VB.NET, we need to establish a connection to the database. This involves creating a connection string and establishing a connection to the database.

Creating a Connection String

A connection string is a string of characters that contains information about how to connect to a database. The connection string typically includes information such as the server name, database name, username, and password.

Establishing a Connection

Once we have created a connection string, we can use it to establish a connection to the database. We can do this by creating an instance of the SqlConnection class and passing the connection string to its constructor.

Executing SQL Queries

SQL (Structured Query Language) is a programming language that is used to manage relational databases. In VB.NET, we can execute SQL queries by creating an instance of the SqlCommand class and passing the SQL query to its constructor.

Retrieving Data from a Database

Retrieving data from a database involves executing a SQL query that retrieves the desired data from the database. We can retrieve data using the SELECT statement in SQL. Once we have executed the query, we can use the SqlDataReader class to read the data from the result set.

Updating Data in a Database

Updating data in a database involves executing an SQL query that modifies the existing data. We can use the UPDATE statement in SQL to update data in a database. Once we have executed the query, we can use the ExecuteNonQuery method of the SqlCommand class to execute the query and update the data in the database.

Inserting Data into a Database

Inserting data into a database involves executing an SQL query that adds new data to the database. We can use the INSERT statement in SQL to insert data into a database. Once we have executed the query, we can use the ExecuteNonQuery method of the SqlCommand class to execute the query and insert the data into the database.

Deleting Data from a Database

Deleting data from a database involves executing an SQL query that removes data from the database. We can use the DELETE statement in SQL to delete data from a database. Once we have executed the query, we can use the ExecuteNonQuery method of the SqlCommand class to execute the query and delete the data from the database.


Transactions are used to ensure that a group of database operations are executed as a single unit of work. In VB.NET, we can use the Transaction class to begin a transaction, execute a series of SQL queries, and then commit or rollback the transaction based on the results.

Working with Stored Procedures

Stored procedures are precompiled SQL statements that are stored in a database. In VB.NET, we can execute stored procedures by creating an instance of the SqlCommand class and passing the stored procedure name to its constructor.

Working with Views

Views are virtual tables that are based on the result of an SQL query. In VB.NET, we can work with views by executing an SQL query that selects data from a view, just like we would with a table.

Error Handling in VB.NET Database-Programming

Error handling is an important aspect of database-programming. In VB.NET, we can handle errors using the Try…Catch…Finally statement. We can also use the SqlException class to handle specific database-related errors.

Best Practices for VB.NET Database-Programming
