Difference Between JDBC and ODBC


ODBC (Open Database Connectivity) is the accepted method for accessing databases among organisations and programmers. A database is linked to other programmes, such as word processors, spreadsheets, and others, through programming.

A link between an application and a database is essentially what is an access-control mechanism for databases that apps may use. SQL commands are performed in this manner. In order to assist with query processing while connecting to a database from an application, ODBC is required. With the help of ODBC, software or operating system may connect to databases.

It has several systems and driver-defined functions that enable programmers to communicate with ODBC-compliant databases. We load a library into an application to access databases. For the specified database, we require an ODBC driver.


JDBC, which stands for Java Database Connectivity, is a Java specification that enables Java to interact with databases using JDBC drivers. This is crucial because it enables interaction between this driver's activities and database operations.

JDBC is a crucial component of programming and integrating a database. Without JDBC, using a database is quite challenging. A standard interface for the Java programming language for accessing databases is called Java Database Connectivity (JDBC). It is not tied to any one database, software, or platform in particular and is more abstract than a database's native interface. The goal of JDBC was to reduce the amount of code required to access a database.

It is a layer of software that enables developers to use a comparable set of Java code to access almost any database. Regardless of the programming language or kind of application, JDBC is a standard method of accessing a database. It offers a standard, cross-platform method of data access. The JDBC API was modelled around the ODBC Database Access Descriptor interface.

Differences between JDBC and ODBC:

  1.  Open Database Connectivity (ODBC) is essentially a standardised application programming interface for communicating with and accessing database management systems, whereas Java Database Community is essentially an API for the Java language to determine the client's access to database features. ODBC uses a procedural approach, whereas JDBC is object-oriented. Since JDBC is built in Java, it can only be upgraded and used with Java-based languages, but ODBC may be used with any language. Since JDBC is primarily based on Java, it is platform independent. Therefore, it is compatible with all systems, including those based on Linux and Microsoft Windows. However, ODBC is an exception to this rule and may only be used with Microsoft Windows systems.
  2. The ODBC architecture primarily consists of four components: the driver, Driver Manager, API, and Data Source. While the fundamental JDBC architecture essentially comprises two layers, namely JDBC API and JDBC Driver API, it does enable both two-tier and three-tier layer processing DB models.


DefinitionTo identify the client's database access characteristics, Java Database Community (JDBC) essentially functions as an application programming interface for the Java programming language. A popular application programming interface (API) for connecting with and accessing database management systems is called Open Database Connectivity (ODBC).
ArchitectureAlthough JDBC API and JDBC Driver API make up its two main architectural levels, the basic JDBC design supports both two-tier and three-tier layer DB model processing.The driver, driver manager, API, and data source are the four key parts of the ODBC architecture.
Platform dependencyJDBC, by default, is a platform-independent technology.In the case of ODBC, it can only be used on systems that are Windows-based.
Mode of Operation JDBC is primarily based on the Java programming language and can be natively compiled at runtime.Because ODBC uses the Visual Basic programming language primarily, the code must first be evaluated before it can be run.
SecuritySince users often do not have access to the primary system settings when using JDBC, violations and security flaws may be rapidly fixed.Because ODBC is a more user-interactive server, it is more prone to user mistakes. JDBC would therefore be a superior option from a security standpoint.


Data may be stored, retrieved, and updated using SQL databases. The databases that serve as the foundation of any corporation, enterprise, or organisation may be created using this method. However, there are two distinct ways to build databases and communicate with them. Open Database Connectivity is the acronym for this. Through a number of applications, this approach enables database interaction. JDBC, or Java Database Connectivity, is a technique that enables database interaction with Java applications.
