Hibernate allows us to do object relational mapping. Simply this mean, conversion of objects derived from java classes inside the application, directly to tables in the database.
This will reduce the effort utilized in drawing ER diagrams, normalization (conceptual design) as well as physically writing SQL coding to complete the physical design inside the RDBMS.
Hibernate will prevent getting your java code dirty via writing SQL within it. If you use hibernate, no sql within your java application at all.
Also hibernate provides:-
• Caching of frequently used data record. Its several times efficient than retrieving from the database.
• Needn’t opening and closing database connections. This will prevent memory leakage problems
• Allow the java application to work with multiple DBMSes.
• Small change in the java code will alter the table in the DB. Needn’t dropping the table.
• 80% of code reduction in the application program
When the required operation was initiated from the application, hibernate is versatile enough to auto generate the required SQL coding

Go to this site called www.hibernate.org/downloads
After going into the site .. notice some changes
Look at the release bundles .. under the release bundle , download the latest version

Add those into the library.. all those jar files to the library
And then add a xml file and name as hibernate.cfg
And then go to project file and search for a file in the name of hibernate.cfg.xml
And from that get the one with the highest capacity, and then paste it in the xml file
Then change the local host thingy user name and password and all
Go to library and add hibernate jar file
Then go into hibernate3.jar and in that go to org.hibernate.dialect and in that go get mysqldialect
And paste that name and path thingy in the dialect part

Prepositions “at”, “on” and “in”

...Prepositions “at”, “on” and “in” The prepositions “at”, “on” and “in” are function words which do not have clear lexical meanings and obvious concepts associated with them. However, these prepositions are important because they specify grammar relations by connecting the content words such as nouns, verbs, adjectives and adverbs to a larger grammatical context. For instance, polar bears hibernate in the winter. This sentence shows that polar bears hibernate during or throughout the winter by just using the preposition “in” before “the winter”. The meaning of the sentence changes if we replace “in” with “at” or “on” in the above sentence. In terms of morphology, “at”, “on” and “in” are all morphemes of a single syllable. Morpheme is an arbitrary union of a sound and a meaning (or grammatical function) that cannot be further analyzed. Even though the structure of these morphemes are simple as they are all made up of two alphabets and one syllable, but their functions are not limited. They can be used in other contexts apart from the context related to time. “At” is used as a preposition to show a point in certain space. For example, he was standing at the door. The usage of “at” point out specifically that he was standing right at the door. It is used to show an intended aim or object towards which a thing or action is directed. For example, he shot at the bird, but missed it. It can be used to show the cause of an action or feeling as in this sentence “I was......

...might not make it through alive, and is forever changed by the experience. On an individual level, large mammals tend to live significantly longer than smaller ones. For example, elephants can live up to 70 years, while shrews are lucky to reach two. Because of their faster generation times, small mammals should evolve faster, and small mammal species and genera should appear and go extinct faster – but this is not the case. But overall, small mammals’ ability to hibernate or enter a state of torpor seems to give them the largest benefit for prolonging their species duration. And the small mammals that didn’t hibernate had relatively faster evolution rates, as they were forced to cope with the elements. The longest living genera in the study were a mole, two gliding squirrels, and two dormice, which lasted about 16 million years, and all had the ability to burrow or hibernate. The tapir was the only large mammal that evolved at a slow rate more akin to the smaller mammals. Most large mammals that didn’t hibernate evolved into a new species or went extinct in just a few million years.   2.(5pts)  Draw J and S shaped curves of population growth.  Label both axes.  Describe situations in nature in which you would expect to see each of these curves.   YOU NEED TO JUST DRAW A J CURVE AND S CURVE ONCE YOU PRINT IT OUT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Horned Lizard

...gives them their name horned lizard or horny toad. The horny toad can be found in Texas, Georgia, Arkansas, Florida, Louisiana, the Carolinas, and Mexico. The Texas horny toad is the largest and most widely distributed of the 14 species of horned lizards in the western United States and Mexico. These unique looking creatures have a flat body. The head of a horny toad has many horns; the two middle head spines are much longer than the other horns. Most of the Texas horned lizards have a light line that goes from its head down the middle of its back. The horned lizard is the only species that has dark brown stripes that go down from their eyes across the top of their head.  The Texas horned toad hibernates from September or October to around late April or May. While the horny toad hibernates they slow their metabolism down so they can go for long periods of time with no food or water. Their mating usually occurs soon after hibernation. After the female and the male mate, the female will then carry her eggs for a period of time as they develop. The female horny toad will choose a nest and then she will dig a slanted tunnel and lay 13 to 45 eggs. After she buries her eggs she may sit on the tunnel entrance for one night, she leaves the nest and never comes back to her eggs....

Jboss Interview Question

...data with JBoss Messaging to move it where it is needed for computation or event-based programming Q:What do you know about Seam ? A: Built on the standards JavaServer Faces and EJB 3.0, JBoss Seam unifies component and programming models and delivers a consistent and powerful framework for rapid creation of web applications with Java EE 5.0. Seam simplifies web application development and enables new functionality that was difficult to implement by hand before, such as stateful conversations, multi-window operation, and handling concurrent fine-grained AJAX requests. Seam also unifies and integrates popular open source technologies like Facelets, Hibernate, iText, and Lucene.   Q:Does Seam run on other application servers besides JBoss ? A: Seam runs beautifully on other application servers - just like everything else the Hibernate team does, this is not a JBoss-only thing. Q:What's JBoss JBPM ?  A: JBoss jBPM is a platform for process languages. At the base there is a java library to define and execute graphs. The actual process constructs like e.g. send email, user task and update database are defined on top of this. Every process language is made up of a set of such process constructs. And that is what is pluggable in this base library. On top of the JBoss jBPM base library, there are implemented several process languages as a set of process constructs: jPDL, BPEL and SEAM pageflow: * jPDL is a process language with a clean interface to Java and very......

Research Paper

...Hibernate ORM (Hibernate in short) is an object-relational mapping framework for the Java language, providing aframework for mapping an object-oriented domain model to a traditional relational database. Hibernate solves object-relational impedance mismatch problems by replacing direct persistence-related database accesses with high-level object handling functions. Hibernate is free software that is distributed under the GNU Lesser General Public License 2.1. Hibernate's primary feature is mapping from Java classes to database tables (and from Java data types to SQL data types). Hibernate also provides data query and retrieval facilities. It generates SQL calls and relieves the developer from manual result set handling and object conversion. Applications using Hibernate are portable to supported SQL databases with little performance overhead[citation needed].
