Relational Databases For each table, identify the primary key and the foreign key(s). If a table does not have a foreign key, write None in the space provided. PRIMARY KEY FOREIGN KEY Truck TRUCK_NUM BASE_CODE, TYPE_CODE Base BASE_CODE TYPE_CODE Do the tables exhibit entity integrity? Answer yes or no, and then explain your answer. ENTITY INTEGRITY EXPLANATION Truck All rows under the primary key TRUCK_NUM are uniquely identified and there are no null entries Base All rows under the primary key BASE_CODE are uniquely identified and

This is one of the greatest limitations of this technology. A second major disadvantage of RDBMS-based systems is their lack of support for image- and spatial-based databases that include Computer-Aided Design (CAD) drawings, 3D rendering and model-based data. Their table-based structure is inefficient in defining the attributes of these data types and lacks the necessary data tagging and data types to manage imaging and CAD-based design files and data

They in short link and map ideas that already exist, creating real time answers to questions as they are applied to new and archived knowledge or action plans. According to IDC reports, most data warehouses will be stored in a columnar fashion and not in rows, reporting and data collection problems will be solved with databases that have no formal schema at all, horizontal scalability through clustering will be achieved

These factors further accelerate the value and TCO of databases over time. Describe the features, tools, and utilities of Structured Query Language (SQL). How can tasks be automated with SQL? SQL has specifically been designed with features, tools and utilities to enable programmers to support nth-tier data architectures in addition to legacy client-server computing scenarios. The development and continual improvement of the features, tools and utilities of SQL for automating tasks

Database Data Warehousing Design Data warehousing is a powerful tool that business organizations use to enhance competitive advantages. Data warehousing supports business decision by collecting, organizing and consolidating data for analysis and reporting using tools such as OLAP (online analytical processing ) and data mining. Typically, the relational database technology is generally being used to design a data warehousing and a relational database is a database having collection of tables, and
