HBASE Vs. RDBMS Top Differences You can Unlock Now

HBASE in the Big data context has a lot of benefits over RDBMS. The listed differences below make you understandable why HBASE is popular in Hadoop (or Bigdata) platform. Let us check one by one quickly. HBASE Vs. RDBMS Differences Random Accessing HBase handles a large amount of data that is store in a distributed manner in the column-oriented format while RDBMS is systematic storage of a database that cannot support a random manner for accessing the database. Database Rules RDBMS strictly follow Codd's 12 rules with fixed schemas and row-oriented manner of database and also follow ACID properties. HBase follows BASE properties and implement complex queries. Secondary indexes, complex inner and outer joins, count, sum, sort, group, and data of page and table can easily be accessible by RDBMS. Storage From small to medium storage application there is the use of RDBMS that provide the solution with MySQL and PostgreSQL whose size increase with concurrency and performance.  Codd'

IBM PML Vs Google MapReduce why you need to read

IBM Parallel Machine Learning Toolbox (PML) is similar to that of Google's MapReduce programming model (Dean and Ghemawat, 2004) and the open source Hadoop system,which is to provide Application Programming Interfaces (APIs) that enable programmers who have no prior experience in parallel and distributed systems to nevertheless implement parallel algorithms with relative ease.

Google MapReduce Vs IBM PML

  1. Like MapReduce and Hadoop, PML supports associative-commutative computations as its primary parallelization mechanism
  2. Unlike MapReduce and Hadoop, PML fundamentally assumes that learning algorithms can be iterative in nature, requiring multiple passes over data.
  3. The ability to maintain the state of each worker node between iterations, making it possible, for example, to partition and distribute data structures across workers
  4. Efficient distribution of data, including the ability of each worker to read a subset of the data, to sample the data, or to scan the entire dataset.
  5. Access to both sparse and dense datasetsParallel merge operations using tree structures for efficient collection of worker results on very large clusters.
  6. In order to make these extensions to the computational model and still address ease of use, PML provides an object-oriented API in which algorithms are objects that implement a predefined set of interface methods.

PML Unique Features

  • The PML infrastructure then uses these interface methods to distribute algorithm objects and their computations across multiple compute nodes-An object-oriented approach is employed to simplify the task of writing code to maintain, update, and distribute complex data structures in parallel environments.
  • Several parallel machine learning and data mining algorithms have already been implemented in PML, including Support Vector Machine (SVM) classifiers, linear regression, transform regression, nearest neighbors classifiers, decision tree classifiers, k-means, fuzzy k-means, kernel k-means, principal component analysis (PCA), kernel PCA, and frequent pattern mining.
