Database Design Models and Database Management Systems, Research Paper Example

Data modeling, or what is normally called database design, is a foundation footstep in database development. Database implementation follows data modeling for database design; that is the implementation depends on the database software utilized. Understanding data models is significant for understanding the full range of data representation alternatives, which might have when one, desire to design and implement a database. A database model is developed as the basis for a particular database design, and is constrained by what data model that have chosen as the basis for developing different designs. Numerous data models are described in terms of the geospatial (abstract) data types that form the basis of those data models. Data models deals with classes of data, and thus is really more about information groups (Cova & Goodchild, 2002).

Database management systems (DBMS) are a computer that is designed to manage organization’s database, which a huge set of structured data. DBMS should guarantee that transactions are executed completely and separately of other transactions. A necessary feature of a DBMS is that a transaction must execute atomically, or as if it is the only transaction running. Alongside, DBMS makes sure that atomicity even if system crashes in the middle of a transaction. It provides all-inclusive and up-to-date coverage of the basics of database systems. Thus, data management systems enables organizations to manage three aspects: the data, the database engine ,which permits data to be accessed , modified and locked; data integrity ,as well as uniform administration processes; and database schema that defines database’s logical structure. The DBMS is possibly most helpful for offering a centralized outlook of data, which may be accessed by numerous users, from several locations, in a controlled way (Martin, 2006).
