Final answer:
A relational database is preferred over a flat-file database due to its organization and flexibility. A data warehouse is a central repository for data analysis, while a clinical repository stores clinical data. A poorly designed database can lead to errors and inefficiencies. The most common types of healthcare databases are the EHR and PACS databases.
Step-by-step explanation:
A relational database is a better choice than a flat-file database because it allows for easier organization and manipulation of data. In a relational database, data is organized into tables with relationships established between them, allowing for efficient searching and retrieval of information. Flat-file databases, on the other hand, store information in a single table, which can lead to data redundancy and difficulty in querying.
A data warehouse is a centralized repository that stores large amounts of data from various sources for analysis and reporting purposes. It is designed to support decision-making processes by providing a consolidated view of data from multiple systems. A clinical repository, on the other hand, is a subset of a data warehouse that specifically stores clinical data, such as patient records and medical history.
A poorly designed database can have several negative impacts. It can lead to data inconsistencies, redundancies, and errors, which can affect the integrity and accuracy of the information stored. It can also result in slow performance and decreased overall efficiency.
The two most common types of databases used in healthcare are the Electronic Health Record (EHR) database and the Picture Archiving and Communication System (PACS) database. EHR databases store patient health records, including medical history, lab results, and medication information. PACS databases store medical images, such as X-rays and CT scans.
