Sachdeva for each non-null attribute value whereas EAV stores three entries per non-null attribute value. This is not true every time. OEAV constructs 32 bit code for each value regardless of space taken by attribute name and value (in case of EAV). This may lead to wastage of space. Attribute Centric Queries. Comparison of the time taken to execute the attribute centric queries is shown through charts in fig. 6(b) and 6(c). When a single attribute is to be selected; Dynamic tables performed best as only one table was to be accessed.

However, Big Data is actually characterized by the 4V’s – Volume, Variety, Velocity and Veracity.

It becomes important to normalize the text by applying a series of pre-processing steps. We have applied an extensive set of pre-processing steps to decrease the size of the feature set to make it suitable for learning algorithms. We have given an illustration of a tweet in Fig. 2. The frequency of such patterns per tweet, cut by datasets is given in Tab. 3. Following which we also give a brief description of pre-processing steps taken. Table 3.
