Implementing a well though-out strategy can spell success for your company. A proper needs analysis should be done to identify the specific 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. In addition, 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 one time. On the other hand, when are referring to function, desktop servers are very efficient, user-friendly and are very affordable 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. When building the data model you must affirmatively decide whether a NULL value will be permitted for a column and, if so, what it means.
