LOGICAL DATA MODELING To start with Cassandra data modeling, we are ready to begin designing Cassandra tables. From the conceptual model we must create a logical model containing a table for each query, capturing entities and relationships. Then identify the primary entity type for which… Read More
RULES FOR DATA MODELLING IN CASSANDRA: Cassandra is a query language which is resembles with SQL, but the modulation of data is completely different when compared with other data types. In Cassandra, a worst model of data can lower the performance, especially when the data… Read More
DATA MODELING IN CASSANDRA: Data modeling is the process of identifying entities and their relationships. In relational databases, data is placed in normalized tables with foreign keys used to reference related data in other tables. Queries that the application will make are driven by the… Read More
