Relational Data Model Versus No SQL Data Model Rutu Patel CSIT 555 Database Systems Midterm Research Paper [1] INTRODUCTION: The term database can be defined as the collection of systematic, well-ordered and structured data that can be easily and efficiently handled, retrieved and upgraded on a periodic basis depending on its requirements. The structure and organization of any database is based upon its respective database model. A unique database model is implemented by each database depending

Conceptual data model Conceptual data model to build the conceptual representation of the database, which includes identification of the important entities, relationships and attributes. A conceptual data models identifies the highest level relationships between the different entities. Features of conceptual data model include:-  No attribute is specified  No primary key is specified  Includes the important entities and the relationships among them. At this level the data model attempts to

SDLC. Developing an enterprise data model will ensure the business requirements are being met and, in the long run, spell success for the enterprise. The two entity relationship diagrams that the rental car company has established are 1) a conceptual data model and 2) a logical data model. After using the process of building these foundational models, the rental car company can move on to the physical model starting to finalize and complete the database. The first data model, the conceptual model,

Databases, Electronic Healthcare Information Systems, Data Sets and Data Standards Patient data is crucial to healthcare practice. Having the ability to create, modify, delete, and view patient data is the most important aspect of healthcare. A vital storage mechanism to perform the above functions is a database. A database is essential in development of Electronic Health Record system A database is an organized collection of data saved as a binary-type file on a computer (Sayles, 2013). Binary-type

Relational Database Management System is a database where data is represented as a set of relations in which data is stored. RDBSM is the basic for SQL. RDBSM contains a table (Is where the data of RDBMS is stored in) and the table contains a field (It is the smaller pieces of the table/ attributes of the table.), records (Also known as a row. It is a single entry in the table. It lies horizontally on the table) and columns (Columns lie vertical on the table. It contains all of the information related
