These implementations are classified as follows: Type one, Style two, Variety 3 and kind 4.
Type 1: Motorists that employ the JDBC API being a mapping to another knowledge obtain API, like ODBC (Open Databases Connectivity). Drivers of this type are typically dependent on a local library, which limits their portability. The JDBC-ODBC Bridge is undoubtedly an illustration of a sort 1 driver.
Type 2: Motorists which have been prepared partly inside the Java programming language and partly in indigenous code. These drivers use a local shopper library distinct to the data resource to which they hook up. Yet again, due to indigenous code, their portability is limited. Oracle's OCI (Oracle Simply call Interface) consumer-aspect driver is definitely an illustration of a sort two driver.
Type 3: Drivers that make use of a pure Java client and communicate with a middleware server employing a database-independent protocol. The middleware server then communicates the customer's requests to the info supply.
Type 4: Motorists that happen to be pure Java and put into action the community protocol for a specific knowledge resource. The consumer connects on to the info supply.
REMOTE METHOD INVOCATION (RMI)
Distant approach invocation enables apps to contact object approaches located remotely, sharing methods and processing load across programs. In contrast to other devices for distant execution which have to have that only basic details varieties or described structures be passed to and from methods, RMI permits any Java item type to be used - regardless of whether the consumer or server hasn't encountered it prior to. RMI lets each client and server to dynamically load new item types as necessary.
a) Take into account the comply with scenario:
Developer X writes a assistance that performs some valuable perform. He regularly updates this service, adding new features and improving existing ones. Developer Y needs to utilize the support supplied by Developer X. However, It really is inconvenient for X to provide Y by having an update when.
The shopper must Get in touch with an RMI registry, and ask for the title on the support. Developer Y will not know the precise place on the RMI support, but he is aware of sufficient to Call Developer X's registry. This could level him within the path from the services he hopes to phone.
Developer X's services changes on a regular basis, so Developer Y doesn't have a duplicate of the class. Not to fret, because the shopper instantly fetches The brand new subclass from a webserver where The 2 developers share lessons. The new course is loaded into memory, as well as the client is able to use the new course. This happens transparently for Developer Y - no more code need to be prepared to fetch the class.
