JAVA Database Connectivity (JDBC) JDBC lets Java programmers connect to a database, query it or update it using SQL. Java and JDBC have an essential advantage over other database programming environments since the programs developed with this technology are platform-independent and vendor- independent. Because of its universality Java and JDBC could eventually replace proprietary database languages. The Design of JDBC JavaSoft's JDBC consists of two layers: the JDBC API and the JDBC Driver Manager API. The JDBC API is the top layer and is the programming interface in Java to structured query language (SQL) which is the standard for accessing relational databases. The JDBC API communicates with the JDBC Driver Manager API , sending it various SQL statements. The manager communicates (transparent to the programmer) with the various third party drivers (provided by Database vendors like Oracle) that actually connect to the database and return the information from the query.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
