- 2. Slide 2 www.edureka.co/persistence-with-hibernate At the end of this module, you will be able to understand: Objectives Java Enterprise Java Enterprise Architecture Hibernate Java EE with Hibernate ORM using Hibernate Lucene Lucene search and index Lucene use case NoSQL NoSQL v/s SQL NoSQL with OGM NoSQL use case Job Trends
- 3. Slide 3 www.edureka.co/persistence-with-hibernate Provides collection of APIs and runtime environments to support Enterprise applications Community driven software Defines standard specifications which can be implemented by vendors Provides services for: » Persistence » Messaging » Web » Transactions Web services support using JAXRS(Rest) and JAXWS(SOAP) JAVAEE – Enterprise Edition
- 4. Slide 4 www.edureka.co/persistence-with-hibernate JAVA Enterprise Architecture
- 5. Slide 5 www.edureka.co/persistence-with-hibernate Hibernate An Object Relational Mapping library of java language for object persistence and SQL databases Transparent persistence of java objects with relational database Provides query language in synch with SQL Open source library Provides solutions for object relational impedance mismatch problems HIBERNATE
- 6. Slide 6 www.edureka.co/persistence-with-hibernate JavaEE with Hibernate HIBERNATE Objective is to solve the complexities existed in EJB2 persistence architecture Provided an effective Java persistence API enabling hibernate to work with different databases easily Annotations provide meta data about table column definitions at the model level Entities are developed independent of the underlying database Derby Mysql Oracle
- 7. Slide 7 www.edureka.co/persistence-with-hibernate ORM using Hibernate Provides a simple API for storing and retrieving Java objects directly to and from the database Non-intrusive: No need to follow specific rules or design patterns Transparent: Your object model is unaware Java Object: int id; String name; String getName() int getId() void setName(String) SQL Table: id [int] primary key, name [varchar(50)] Magic Happens Here (O/R Mapper – i.e. Hibernate)
- 8. Slide 8 www.edureka.co/persistence-with-hibernate Lucene – Full Text Search An Apache library Full text search capability Developed on java API Query results are returned by relevance Fast, flexible and stable Easy to integrate lucence search functionality to application
- 9. Slide 9 www.edureka.co/persistence-with-hibernate Lucene – Indexing One of the most base functionality of Lucene Fields in the documents are analyzed by the IndexWriter Creates/Updates the indexes Indexes created/updated are equivalently stored/updated in directory Document IndexWriter Directory
- 10. Slide 10 www.edureka.co/persistence-with-hibernate Lucene – Search Search operation is basically carried via IndexSearcher Directory having indexes are passed to IndexSearcher IndexSearcher reads the indexes in the directory with the help of IndexReader Query to search is created using the QueryParser Search performed with IndexSearcher against the query created by QueryParser IndexSearcher returns TopDocs which contains the complete search details TopDocsIndexSearcherQueryParser IndexReader Directory
- 11. Slide 11 www.edureka.co/persistence-with-hibernate Use-Case of Search Lucence provides very efficient search capabilities on file system Hibernate Search built on top of the Lucence search engine to address the short comings of lucence in domain object models Similarly to Hibernate which has been built in top of the SQL databases, Hibernate search built on top of Lucence Hibernate address the short comings of lucence in domain object models with annotations Manages entities when query made to database or as lucence query to index
- 12. Slide 12 www.edureka.co/persistence-with-hibernate Use-Case of Lucene Search (Contd.) How hibernate can perform search on the database with Lucene as Lucene can do effective searching on file system
- 13. Slide 13 www.edureka.co/persistence-with-hibernate Use-Case of Lucene Search (Contd.) Hibernate + Hibernate Search Database Lucence (Index) Search Request
- 14. Slide 14 www.edureka.co/persistence-with-hibernate DEMO - LUCENCE APPLICATION
- 15. Slide 15 www.edureka.co/persistence-with-hibernate NoSQL What is NoSQL? Not Only SQL Performs storage and retrieval of data in relational databases other than tabular format Extensively used in big data domain Lacks support for ACID Can handle structured, semi structured and unstructured data
- 16. Slide 16 www.edureka.co/persistence-with-hibernate NoSQL v/s SQL SQL NoSQL SCALING SQL relational databases multiple servers are used for database load resulting in expensive approach NoSQL databases can scale horizontally with the help of nodes BIG DATA Have limitations in handling huge data volume Can handle huge volume of data in a distributed database approach Schema Can be changed any time Changing schema is always a challenge once defined Server Cost Proprietary servers and storage systems are expensive Use of cheap commodity hardware
- 17. Slide 17 www.edureka.co/persistence-with-hibernate Hibernate OGM OGM – Object Grid Mapper It provides Java Persistence (JPA) support for NoSQL solutions Object Relational Mapping for NoSQL Databases Provides support for most of the NoSQL database types Scaling of relational databases with a NoSQL front end and with no change in domain model HIBERNATE OGM
- 18. Slide 18 www.edureka.co/persistence-with-hibernate Use-Case of NoSQL How hibernate can perform no sql on the underlying existing models of the database.
- 19. Slide 19 www.edureka.co/persistence-with-hibernate Use-Case of NoSQL (Contd.)
- 20. Slide 20 www.edureka.co/persistence-with-hibernate DEMO - OGM with Mongo
- 21. Slide 21 www.edureka.co/persistence-with-hibernate Hibernate Skills Hibernate Tools – Enables RDBMS mappings & associations with domain objects, hence should have knowledge on databases SQL Skills – Demonstrates the traditional SQL skills to understand table relations Coding Skills – Should possess java coding skills in using annotations & xml mappings for domain objects OOP Skills – Should possess Object oriented programming skills to deal with Hibernate inheritance and polymorphism Skills Products Database Mysql, Oracle or any RDBMS vendor Coding Java Configuration Management Eclipse, Hibernate tools SQL Mysql, Oracle or any RDBMS vendor Hibernate Skill Matrix
