Advantages and Disadvantages It automatically creates the XML format of data from the database. It does not require the content to be converted. It provides full support to query and stored procedure. It provides support to both Synchronous and Asynchronous processing.
The JDBC API was modeled after ODBC, but, because JDBC is a Java API, it offers a natural Java interface for working with SQL. JDBC is needed to provide a "pure Java" solution for application development.
The JDBC Driver is a set of classes that implement the JDBC interfaces to process JDBC calls and return result sets to a Java application. ... An application uses the connection object to create statements. Statement, PreparedStatement, and CallableStatement objects are used for executing SQL statements.
Today, there are five types of JDBC drivers in use:
Advantages for using this type of driver include the following: Allows access to almost any database since the databases ODBC drivers are readily available. Offers significantly better performance than the JDBC/ODBC Bridge. Limited Java feature set.
As you can see, with less number of records being fetched from the database, C(ODBC) performed better. But as the number of records were increased, Java(JDBC) came out as the winner.
JDBC (Java Database Connectivity) is the Java API that manages connecting to a database, issuing queries and commands, and handling result sets obtained from the database. Released as part of JDK 1.
ODBC is an SQL-based Application Programming Interface (API) created by Microsoft that is used by Windows software applications to access databases via SQL. JDBC is an SQL-based API created by Sun Microsystems to enable Java applications to use SQL for database access.
Open Database Connectivity (ODBC) is an open standard Application Programming Interface (API) for accessing a database.
ODBC is used between applications JDBC is used by Java programmers to connect to databases With a small "bridge" program, you can use the JDBC interface to access ODBC- accessible databases. The JDBC API supports both two-tier and three-tier models for database access.
PostgreSQL JDBC Driver You can use any python module that supports JDBC connection.
Basically you just import the jaydebeapi Python module and execute the connect method. This gives you a DB-API conform connection to the database. The first argument to connect is the name of the Java driver class. The second argument is a string with the JDBC connection URL.
Jython is a version of the Python programming language that runs on the Java platform. It allows users to write programs in Python and compile them to Java bytecodes that run directly on a Java Virtual Machine, or JVM. It's similar to otherJVM languages like; Scala, Kotlin, Groovy, or Clojur.
Steps to connect to ODBC database in Python with pyodbc module
PyPyODBC is a pure Python script, it runs on CPython / IronPython / PyPy , Version 2.
Connect to a SQL Server instance Start SQL Server Management Studio. The first time you run SSMS, the Connect to Server window opens. If it doesn't open, you can open it manually by selecting Object Explorer > Connect > Database Engine. For Server type, select Database Engine (usually the default option).
SQL Server 2019 Express is a free edition of SQL Server, ideal for development and production for desktop, web, and small server applications.
SQL Server 2019 pricing
In Object Explorer, connect to an instance of the SQL Server Database Engine and then expand that instance. Right-click Databases, and then click New Database. In New Database, enter a database name. To create the database by accepting all default values, click OK; otherwise, continue with the following optional steps.
The best way to learn SQL is by practicing it. Install a free open source database so you can start writing and running simple queries using your own data. MySQL is a popular free database that is compatible with most operating systems.

The average cost to rent a small business dedicated server is $100 to $200/month. You can also setup a cloud server starting at $5/month, but most businesses would spend about $40/month to have adequate resources. If you wanted to purchase a server for your office, it may cost between $1000-$3000 for a small business.
Pretty much any computer can be used as a web server, provided it can connect to a network and run web server software. Since a web server can be quite simple and there are free and open source web servers available, in practice, any device can act as a web server.
