the field of science in which biology, computer science, and information technology merge to form a single discipline.

Conceptual Data Modeling (CDM)Make explicit the structural properties of data, and as such are useful for capturing, refining, and communicating details about the data in a laboratory or database.
Entity 1*A type of notation that describes entity types and relationships.Entity 2Attributes/propertiesThe design processRequirements AnalysisConceptual DesignLogical DesignDatabase RequirementsConceptual ModelImplementation Model
* There is no universally accepted standard for either the design process or notation.http://www.databaseanswers.org/data_models/hotels/index.htm71. Entity-Relationship Modeling is a type of CDMEntity Types An entity type provides a description of the properties of entities in a domain
Relationships Represents an association between two or more entity types.

String of attributes/properties that define and identify the relationship and are unique to the entity.
2. Unified Modeling Language (UML); another CDMThe standard object modeling language.Notation is the class diagram which describes the attributes, operations, and relationships of a set of objects.
Class DiagramUML versus ERERER was developed earlier for relational databasesER uses keys: when one or more attributes of an entity are used to uniquely identify itUses relational tablesNot truly platform independentUMLUML is object-orientedDo not support keysNot all relationships are given names or rolesIndependent of platformBuilding Useful Networks
Question 1.True/False: Conceptual Data Models (CDMs) are only applicable to bioinformatics research.
Correct Answer: FALSEQuestion 2.Which of the following is not an activity in the design process for conceptual modeling?Requirements AnalysisConceptual DesignConceptual ModelA. B. and C. are all examples of the design process.All of the above and activities can vary as there is no universally accepted process or design.
Question 3.Which of the following is FALSE in regards to Conceptual Data Models (CDMs)?CDMs allow precise statements to made about the data.CDMs are easier to read than to construct.CDMs easily describe all data without including invalid data.Entity Relationship and Unified Modeling Languages are types of CDMsThank you for your attention!References and Images (In order of appearance)http://campus.murraystate.edu/academic/faculty/eweber/bio101/images/cell_to_dna_sm.jpghttp://bioinfo.imdik.pan.pl/mediawiki/images/e/e1/Sek3.jpghttp://asgpb.mhpcc.hawaii.edu/sequence/454sequencer.jpghttp://blog.chron.com/bakerblog/files/legacy/dna.jpghttp://www.nature.com/nature/journal/v464/n7289/images/464680a-i1.0.jpghttp://www.ornl.gov/sci/techresources/Human_Genome/home.shtmlhttp://25.media.tumblr.com/tumblr_loa5m3vYuO1qbh26io1_1280.jpghttp://www.sanger.ac.uk/about/history/hgp/http://en.wikipedia.org/wiki/File:Myoglobin.pnghttp://en.wikipedia.org/wiki/File:1GZX_Haemoglobin.pnghttp://www.databaseanswers.org/data_models/hotels/index.htmhttp://www.schillerlab.net/guides/hiv/image009.pnghttp://www.nature.com/scitable/content/6437/10.1073_pnas0701361104-fig2b_mid_1.jpg
