Store Matrices & Graphs

The matrix or network structure that frequently changes should have flexible storage structure for easy update and indicies that point to the appropriate entry. Also, we need a model that uses the concept of column-iterative methods.

To store the matrices, Hama use a \[http://hadoop.apache.org/hbase/ Hbase\] -- Matrices are basically tables. They are ways of storing numbers and other things. Typical matrix has rows and columns  which is often called a 2-way matrix because it has two dimensions. For example, you might have  to store the matrices.

Matrices are basically tables. They are ways of storing numbers and other things. Typical matrix has rows and columns which is often called a 2-way matrix because it has two dimensions. For example, you might have respondents-by-attitudes. Of course, you might collect the same data on the same people at 5 points in time. In that case, you either have 5 different 2-way matrices, or you could think of it as a 3-way matrix, that is respondent-by-attitude-by-time.

– Just a thought, considering the depleted activity in HBase should we not explore ways to avoid HBase ? --Prasen
– Hbase seems activity at this time, However Yes. We should think about it. --Edward
