  1. 3. software designed to store, retrieve, define, and manage data in a database
  2. 10. allow multiple users to access data at the same time
  3. 11. a phase of database deisgn that involves building a database sketch from requirements gathering and customer information. This sketch will consist of a data model with high-level entities and the relationships between them.
  4. 12. an object in a database that is logically organized in a row-and-column format and contains data about a subject.
  5. 13. the query language used by relational databases
  6. 15. a request for data from a database
  7. 17. a property of an entity that becomes a field in the physical database
  8. 18. a phase of database design that is multifaceted and complex and is centered around surviving without changing the meaning of the code.
  9. 19. occurs when the same piece of data is held in two separat locations
  10. 20. a phase of database design that is an implementation-nonspecific refinement of the work done in the conceptual phase, transforming the concepts into a full-fledged database requirement that will be the foundation for the implementation design
  11. 21. a column in a table that contains a set of data values of the same data type
Down
  1. 1. a phase of database design in which you adapt the logical model for implementation to the host RDBMS
  2. 2. part of conceptual design that becomes a table in the physical database and contains data about an object (NOUN)
  3. 4. describes the data in the database such as where and when it was collected
  4. 5. a primary key from another table that establishes the relationship between the two tables
  5. 6. a means of group objects in a database with a common theme
  6. 7. a field or fields in a table that uniquely identify a row, record, or tuple
  7. 8. a collection of facts or data
  8. 9. rules enforced on data columns of a table that are used to limit the type of data that can go into the table and ensure the accuracy and reliability of the data.
  9. 14. a candidate key selected to identify records in a table
  10. 16. an association between two tables or entities based on a primary key from one table and a foreign key in the second
  11. 22. a person who manages, maintains, and secures data in one or more data systems so that a user can perform analysis for business operations
