Introduction of Data Modelling Tools

Almost all mid to large scale businesses these days rely deliberately on data to make important decisions on a day-to-day basis. The authenticity and consistency of data is of great importance for business users to make quick as well informed decisions. The flow and relationships of data need to be defined and structured to ensure the best results. This process is called Data Modeling. Here, we will discuss top-performing Data Modelling Tools.

To speed up the process and to avoid human errors as much as possible, specialized software is used to help with building a logical data model, creating DDL, and to generate reports that can be helpful while explaining to stakeholders. Let’s look at database design tools and database diagram tools in detail.

Database Design

A good database design is as important as a fishing-net to the fisherman. It is a pre-requisite to work with the database in an efficient way. It is pre-requisite because it lessens the maintenance efforts, decrease chances of errors, provides a mechanism of good conveyance channel between the users and in general reduces efforts of the user to perform task. Database diagram tools provide help in building data models with complexity easy to relatively high and that too with ease.

If we look into more technical terms, there are different phases of database designing to get it completed in an efficient way. The important phases are,

  • Collecting and Analysis— As the name suggest, collecting and analyzing
  • Initial Conceptual Design— Conceptual diagram i.e. E-R diagram, UML Class diagram
  • Initial Logical Design— Primary and foreign keys comes into the picture
  • Normalization Process— To remove redundancy i.e. avoid duplication
  • Physical Design— Finally, the place where database takes place
