Data Bases are of two types. They are SQL database and No SQL database.HBase comes in No SQL databases. Most of the companies changed their storages from SQL databases to No SQL databases. Due to some relaxations in No SQL like Consistence and there is no Validations. Difference between SQL and No SQL, In SQL database “Schema on write” it will validate schema and it will insert the data when we write anything. In No SQL database “Schema on read” there are no validations when we write the data but it applies validation when we read the data. Adavantages of “No SQL”- No validation so we can store huge velocity of data. There are many “No SQL data bases” out of which Hbase. We use Hbase to work in Hadoop. Hadoop is a distributed file system (HDFS) is a batch processing and HBASE is real time. Indexed HDFS is HBase.
Difference between SQL and HBASE:
1.In SQL, while preparing a table we “create and structure” than insert the data.
2.In HBase, we “create” the table and than “structure and data”
If there is no information in SQL, it will show NULL option and if there is no information than it will not show any NULL option.
Column family in HBase training:
Table is a collection of rows and row is a collection of column families and column family is a collection of columns and column is a collection of key value pairs.
Relational Data Base Management System (RDBMS) in HBase training :
- Relational Data Base Management System (RDBMS) is a row oriented.
- It is a Fixed schema.
- RDBMS is not optimized for sparse tables but optimized for joins.
- RDBMS is good for structured data.
- It is build for only small tables.
- It is transactional
- RDBMS have normalized data.
Main features of HBase :
Some of the main features of HBase are as follows
- High-Speed: HBase is used for speedy requirements because it consistent reads and writes.
- Atomic Read and Write: In a row level, HBase offers tiny read and write.
- Scalability: In together linear form and modular form HBase ropes scalability.
- Distributed storage: HBase supports distributed storage like Hadoop Distributed File System (HDFS).
- Data Replication: HBase supports data replication across clusters.
- Map Reduce Support: For parallel processing of large volume of data, HBase supports Map Reduce.
Uses of HBase :
- For big data to have random, real-time read and write access we use HBase.
- On commodity hardware HBase hosts very large tables on the top of clusters.
- HBase storage is used by facebook to store real-time messages.
- HBase is also used by Mozilla to store crash data.
Applications of HBase :
- For fast random access HBase is used.
- HBase internally used by facebook, yahoo, adobe and twitter.
- HBase is also used in medical field for storing disease history of people.
- It is used in sports field for storing match histories.
Characteristics of HBase:
- In HBase importance is recognized with a key.
- In HBase together key and value are a byte-array.
- Its principles are stored in key orders.
- Principles can be accessed very fast by their keys.
HBase Shell in HBase training:
HBase contains a shell using which we can communicate with the HBase. To store HBase data it uses Hadoop file system. It has two Master servers and Region server.
- Gives regions to region servers and takes the help of Apache Zookeeper for this task.
- The state of the cluster is maintained by negolating the load balancing.
- Master Server is responsible for schema changes.
- At a time single master node runs at a time.
- Its availability is maintained with ZooKeeper.
- Data related operations can be handled.
- It handles read and write requests for all the regions.
- Region size can be decided.
- Clients can communicate with Region Servers.
HBase storage model:
HBase storage model are two types Partitioning and Persistance and data availability.
- A table is flat partitioned into regions and each and every region has range of keys.
- Each and every region is maintained by a Region Server.
- A region server can handle multiple regions.
Persistance and data availability:
- HBase data is stored in Hadoop distributed file system (HDFS).
- Region data is cached in memory.
Data storage in HBase :
- Data is deposited in files called Hfiles or deposited files saved in Hadoop distributed file system (HDFS).
- Hfile is a key-value map.
- When statistics is added, it is inscribed to a log called write ahead log and stored in memory.
The table schema is represented by the following key terms:
- Table: Table is a collection of rows.
- Row: Row is a collection of column families.
- Column families: Column families is a collection of columns.
- Column: Column is a collection of key-value pairs.
- Namespace: Namespace is a logical grouping of tables.
- Cell: Cell definition is specified by row, column and version.
Installation of HBase:
Installation of HBase can be done in three modes. They are
- Standalone mode installation
- Pseudo-Distributed mode installation
- Fully Distributed mode installation
1.Standalone mode installation:
- Standalone mode installation does not depend on Hadoop system.
- HBase is the default mode of Standalone mode installation.
- This works against the local file system but only HMaster daemon can run.
- For production environment this is not recommended.
2.Pseudo-Distributed mode installation:
- Pseduo-Distributed mode installation is a combination of Single node Hadoop system and HBase installation.
- This works on Hadoop HDFS.
- All Daemons works on single node.
- For production environment this is recommended.
3.Fully Distributed mode installation:
- Fully Distributed mode installation is the mixture of Multinode Hadoop environment and HBase installation.
- This works on Hadoop HDFS. All daemons works across all nodes there in the cluster.
- For production environment, this is highly recommended.
When we are using large amount of data its process speed must be equal to that data for this hadoop training is the best solution.
After complete installation of HBase. We can work together with HBase in two ways. HBase interactive shell mode and through Java API.
- HBase interactive shell mode: By using HBase interactive shell mode ,we can work with HBase for table operations, table management and data modeling.
- Through Java API: By using through Java API, we can do all types of table and data operations.
Difference between HBase interactive shell mode and Through Java API is HBase interactive shell mode uses shell commands to get connected with HBase and Java API uses Java code to get connected with HBase.
Advantages and Disadvantages of HBase:
Advantages of HBase :
- In HBase, we can share data base.
- We can randomly read and write.
- HBase is also used for online analytical operations.
- High performance and availability.
Disadvantages of HBase:
- HBase does not support SQL structure.
- We cannot replace HBase completely with traditional models.
Learn about Bigdata testing training in our HBase training:
In Bigdata testing, there are three types of functional testing. They are
- Unit testing
- Integration testing
- System testing
These testings are done whether they are functioning or working to the design state.
There is also non functional testing they are performance testing or security testing.
Big data means large amount of data to be stored and it should also be properly maintained.
Characteristics of Big data:
There are three types of characteristics. They are Volume, Velocity and Variety.
- Volume: Volume means large amount of data.
- Velocity: Speed of the data.
- Variety: Variety means different types of data. They are Structured data, Semi-structured data and Unstructured data.
- Big data training is also known as Hadoop testing training.
- Global online training provides the best quality Hadoop testing training at a resonable price.
Learn about Oracle SQL training in our HBase training:
- Oracle deals with number of softwares among all of these softwares, the most important software is Database.
- The details which are entered into the website are stored in a place called Database.
- The data is stored permanently in a tabular way and all the data is related to one another.
- The interaction between the database and the user is done by DBMS (Data Base Management System). At present we are using DBMS is RDBMS (Relational Data Base Management System).
- For using Relational Data Base Management System(RDBMS), we use Structured Query Language (SQL). This language is very easy to learn.
Structured Query Language (SQL) is classified into 5 languages. They are
1.Data Definition Language (DDL)
2.Data Manipulation Language (DML)
3.Data Retrieval Language (DRL)
4.Data Control Language (DCL)
5.Transaction Control Language (TCL)
