Database Design Tools: Finding the Right Fit

Database systems are very essential tools for a business. Implementing a well though-out strategy can spell success for your company. A proper needs analysis should be done in order to distinguish database management system or DBMS that fits with your requirements. Your needs can range from very simple information like for instance the list of your employees and their personal profiles, number of present records and payroll information to more complex transactions between you, vendors and distributors within your supply chain. The effectiveness of collecting, recording and retrieving various bits and bytes of this information depends on the DBMS you choose.

To identify the right DBMS that will best fit for your company’s needs, there are two general categories. The desktop database application and user interface, and the server based database system. The desktop application caters to a single-user interface, hence the name desktop. Furthermore, server databases have mechanisms to make sure of the concurrency of data and are oriented for multiple-user applications. Between the two, the server based database requires more complex data visualization models due to the multiple users that may be interacting with the data at any moment. Nevertheless, when referring to function, desktop servers are very effective, user-friendly and are less expensive database solution than designing entity relationship models for a SQL server for example. Data modeling for Oracle 10g supports a directed and un-directed logical graph as part of Oracle Spatial Network Data Model. Programmers and developers in most computer languages are very familiar with Boolean logic which is a type of decision making utilized by computers to decide if a statement is true or false. A variable may be either true or false. Pervading SQL, however, is the alien idea of three-valued logic. A column can be true, false, or NULL. In constructing the data or information model you must affirmatively make a decision whether a NULL value will be allowed for a column and, if so, what it means.

Consult with an Expert Designer when Necessary

To acquire the most valuable results, you must seek an advice with an expert designer that would help determine database design features and should provide you with the most excellent solution to fit your particular business needs. In some more complex situations the best solution is to design and build a custom DDL for your DBMS. Good quality of database modeling software will help the developer to generate script for a database model change for easier implementation of business changes. The most common database model being used by programmers that is suitable for most business enterprises’ needs is the relational model. It is a record-based model where the inputs are processed in what has been called the Entity-Relationship Diagram method.

Simple ERD diagram examples such as this image reflect an ontology where an entity and its relationship are being categorized and classified. Using the right relational data analysis tools a designer can reverse engineer into more complex SQL server database diagram. Conduct your due diligence thoroughly before selecting the db design tool for your project. Being informed of the differences of each database design software on the market will help to avoid problems with your database system in the long run. Tools like MySQL Workbench and RISE Editor (to name a few) communicates exclusively in their preferred programming language making it incompatible for other database servers. There are a number of prominent database modeling softwarethat not only reliable and user-friendly but also compatibility with other database servers.
