Database Design & Architecture
At Yehuda Oratz Software Development, we specialize in database design and architecture,
along with several other services.
Database design refers to the arrangement of data in a database model. The database designer decides what data needs to be stored and how each data element relates to the others. Our goal is to help businesses by creating systems that are easy to maintain, facilitate data consistency, and do not take up too much storage space, making them more cost-effective.
Yehuda Oratz has experience in relational and dimensional models, each of which has a unique set of advantages. A dimensional model is designed to handle numeric data such as weights, balances, or values. Dimensional models group information very clearly and efficiently. This type of model can be easily adjusted to include more dimensions. It is meant to give businesses the most adjustability as to how they can view their data. Additionally, dimensional models maximize how quickly businesses can recover the data. In a dimensional model, each fact or piece of data is entered in as many ways as possible. For example, when dealing with sales, a date is not just entered as a single date column. Rather, every dimension of a date is split into its own column, such as day, month, year, quarter, etc. This allows businesses to pull very precise information from the database.
Relational models are helpful when looking for a way to organize data, such as transactions. These models are good for displaying data in a realistic manner while decreasing room for error and repetition of information. In a relational database, each category of data is represented in its own table. For example, a customer’s name would be in its own table, and all other information relating to that customer would be stored in other tables that can then be connected to the name table. This way, the customer’s name is only stored once and does not need to be repeated every time the customer has a new transaction.
Evidently, dimensional and relational models can both benefit a business in different ways. It is crucial to identify what the business is trying to discover through its database in order to determine which model will benefit them best. With extensive experience in designing both types of models, Yehuda Oratz can identify exactly what a business needs to improve efficiency.
