Database Design


Database Design Experience

With decades of real-world experience, Parthian Systems knows that the strength of an application depends upon a carefully thought-out database design and implementation. The ability to build powerful, scalable websites and database-driven applications comes from understanding the business problem and translating it into the best architecture, application and database design. Our experts will build a data management solution that meets or exceeds your requirements.

We focus on four major database technologies: Oracle, MySQL, PostgreSQL and SQL Server, including replication, clustering (Oracle RAC) and many other features offered by these platforms. In addition, we can help consolidate and automate many processes to further streamline your organization.

Background Info for Success

Database design overlaps somewhat with database architecture, however, here our aim is to focus on the physical database design. Physical database design is the process of creating a detailed model of the entities (tables, indexes, views) required for the creation of the actual database. This data model should contain all the needed logical and physical design choices and physical storage parameters needed to generate a design in a data definition language (DDL), which can then be used to create a database.

A relational database organizes data in tables (or relations). The relationships that can be created among the tables enables a relational database to efficiently store huge amounts of data and effectively retrieve selected data.

An entity-relationship diagram (ERD) is a specialized graphic that illustrates the relationships between entities in a database. Below is a very simple example of an ERD.

Design Objectives

At a minimum, a well-designed database needs to do the following:

  • Eliminate Data Redundancy: the same piece of data shall not be stored in more than one place. This is because duplicate data not only waste storage spaces but can also easily lead to inconsistencies.
  • Ensure Data Integrity and Accuracy

In addition to these two main points, the database design must allow for scalability of the database (have the ability to handle a growing amount of work in a capable manner).

Experience = Performance

High performance database systems don't happen without thorough planning and analysis. Unfortunately, many times a database is built as a temporary fix which soon becomes a permanent system. Without the proper planning and analysis of your data and applications, your database will soon become the bottleneck to high performance in your applications and ultimately your business. This is where the value of proper database design becomes apparent. At Parthian Systems we first gather your requirements and learn what applications your database systems will support. After gathering this important information we can then begin the process of database design and laying the foundation for a solid, high-performance database system.
