Recommended Reading Different Phases of Database Designing Database designing includes a lot of phases to get it completed in an effective way. Database designing is performed in connection with the application design. The important phases include: 1 Collecting Requirements and their analysis: In this phase, the requirements are collected and their analysis is done. The requirements can be data related as well as functional requirements. This simply means that the concept of primary keys and foreign keys comes into the picture as a part of this phase. Also, the data which is to be stored in the database is also added inside the database. ERD is the baseline of any database. This has the vision to turn any project into a very successful one by complementing the features like Enterprise Architecture, Visual Modeling, Mind Mapping and much more. The software of Visual Paradigm is adopted by many big organizations including Fortune Companies. This is best suitable for UML Modeling. Visit here for further information about this tool. It offers smart visualization features to help you design the database structure and to identify potential errors before any code has been written. This product supports both forward and reverse engineering and is packed with intuitive tools such as smart hints, template projects, fast search, naming conventions. However, you can get started with a fully featured free plan.

Navigator Edition: Academic Edition: The Academic Edition is a time-limited edition and includes a limited number of features.

It is designed to help students to learn creating simple data models. Erwin makes database creation very simple by generating the DDL sql scripts from a data model by using its Forward Engineering technique or Erwin can be used to create data models from the existing database by using its Reverse Engineering technique. In order to create data models in Erwin, you need to have this All Fusion Erwin Data Modeler installed in your system. If you have installed Modelmart, then more than one user can work on the same model.

In the following section, a simple example with a step by step procedure to create a logical data model with two entities and their relationship are explained in detail.

ERwins superior capabilities ensure that data is consistently defined and captured across all your deployment platforms. ERwins Benefits Easy-to-use Design Functionality: Database design is made simple through pointand-click creation of a graphical entity-relationship ER model of your data requirements and data usage rules.

Drag-and-drop functionality allows you to quickly create entities and attributes, tables, and columns, and other model objects. Additionally, ERwins on-diagram editing facilitates quick and easy design changes. Forward Engineering: ERwin generates the physical database schema, including all supported options, from a physical model.

You can quickly reverse-engineer existing databases for incorporation into new development efforts, and then proceed to add new database objects or even redesign the database structure. Manageability: ERwin handles large enterprise models by creating smaller subsets where specific areas can be highlighted. Subsets of large data models are treated as subject areas that are quickly and easily created to make your designated business data model more accessible. Environment Integration: ERwin can design transactional systems, data marts, and data warehouses to be implemented on the same or different platforms.

ERwin supports the most popular desktop and SQL database platforms.

Because ERwin automatically converts datatypes and SQL syntax to match the target server you select, you can reuse a data model for different platforms and implementations. Create independent logical and physical models with unique notation and display options. Split models of older ERwin versions into separate logical and physical models, derive new models from existing models, and link a model to its source so that changes can be synchronized.
