Is JDBC driver database dependent?

The JDBC type 1 driver, also known as the JDBC-ODBC bridge, is a database driver implementation that employs the ODBC driver to connect to the database. The driver is platform-dependent as it makes use of ODBC which in turn depends on native libraries of the underlying operating system the JVM is running upon.

Which JDBC driver gives best performance?

For most applications, the best choice is a pure Java driver, either Type 3, Type 4, or even Type 5.

  • Type 5 JDBC drivers (such as DataDirect JDBC drivers) offer advanced functionality and superior performance over other driver types.
  • Type 4 drivers are the most common and are designed for a particular vendor’s database.

Which JDBC drivers are most time consuming?

1) Type 1 JDBC Driver / JDBC-ODBC Bridge Driver Because, all JDBC calls will go to the ODBC driver through the bridge and then to database. So it is time consuming and raises the performance issues. This type of drivers are not recommended for high transaction java applications.

Which driver is efficient and always preferred for using JDBC applications?

Which driver is efficient and always preferable for using JDBC applications? Type 4 Driver is a Database-Protocol Driver(Pure Java Driver). Its implementation allows the conversion of JDBC calls directly into a vendor-specific database protocol.

  • a. The JDBC-ODBC bridge.
  • b. The JDBC driver manager.
  • c. The JDBC driver test suite.
  • d.

What driver is used in JDBC?

Type-1 driver or JDBC-ODBC bridge driver uses ODBC driver to connect to the database. The JDBC-ODBC bridge driver converts JDBC method calls into the ODBC function calls. Type-1 driver is also called Universal driver because it can be used to connect to any of the databases.

How make JDBC faster?

JDBC performance tips

  1. Use prepared statements.
  2. Tune the SQL to minimize the data returned (e.g. not ‘SELECT *’).
  3. Minimize transaction conflicts (e.g. locked rows).
  4. Use connection pooling.
  5. Try to combine queries and batch updates.
  6. Use stored procedures.
  7. Cache data to avoid repeated queries.

Why is JDBC slow?

Establishing a JDBC connection with a DBMS can be very slow. If your application requires database connections that are repeatedly opened and closed, this can become a significant performance issue. Add more if the connection pool is configured to periodically test database connections.

Which of the following is JDBC-ODBC driver?

What is a JDBC driver and how many JDBC drivers are available?

There are 4 types of JDBC drivers: Type-1 driver or JDBC-ODBC bridge driver. Type-2 driver or Native-API driver. Type-3 driver or Network Protocol driver.

What is JDBC and JDBC drivers?

A JDBC driver uses the JDBC™ (Java Database Connectivity) API developed by Sun Microsystems, now part of Oracle, that provides a standard way to access data using the Java™ programming language. Using JDBC allows you to write one application that can send SQL statements to different data sources.

Which type of driver provides JDBC access via one or more ODBC drivers?

Type one drivers provide JDBC access via one or more Open Database Connectivity (ODBC) drivers. ODBC, which predates JDBC, is widely used by developers to connect to databases in a non-Java environment.

What is the Oracle JDBC thin driver?

The Oracle JDBC thin driver is a Type IV JDBC driver, meaning that it’s platform-independent and does not require any extra Oracle software on the client side to interact with an Oracle database.

Is it possible to use JDBC directly into an application?

Though it is not standard anymore to use JDBC directly into your application because we got many more robust APIs to do this job for us e.g. hibernate and iBatis. But, if you are still struck in there due to specific requirements or simply you are learning it, then below suggestions will help you in writing more fast and efficient code.

Why specify at least the schema in JDBC?

Specifying at least the schema will avoid returning information on all tables for every schema when the request is sent to the server: Secondly, remember that most JDBC drivers populate the ResultSetMetaData object at fetch time when the needed data is returned in select queries.

Is drizzle JDBC faster than connectorj?

While the one-liner makes the Drizzle JDBC faster, with slightly better numbers than ConnectorJ, it is still not as fast as MariaDB. In the MariaDB JDBC connector, there were a couple of improvements to performance which were made since forking.
