- 11. These applications must deal with large volumes of varied data and manage them on external storage.
- 12. Data Management refers to: the storage, access and preservation of the data . It covers the whole lifecycle of the data, from implementation of data designs, policies and procedures to the management of this data, and from backing up data as it is created and used to long term preservation of data.

Editor's Notes
- Specific activities and issues that fall within the category of Data Management include:File naming: the proper way to name computer filesData quality control and quality assuranceData accessData documentation (including levels of uncertainty)Metadata creation and controlled vocabulariesData storageData archiving & preservationData sharing and re-useData integrityData securityData privacyData rightsNotebook protocols (lab or field)

- Thefield is the most primitive building block; each field represents one data element. Forexample, the database of a hospital’s registration system typically has fields such as thepatient’s identification number, name, date of birth, gender, admission date, and admittingdiagnosis. Fields are usually grouped together to form records . A record is uniquelyidentified by one or more key fields In addition to filesabout patients and their diagnoses, treatments, and drug therapies, the database of ahealth care information system will have separate files containing information aboutcharges and payments, personnel and payroll, inventory, and many other topics. Allthese files relate to one another: they may refer to the same patients, to the same personnel,to the same services, to the same set of accounts, and so on. Records that contain similar information are grouped in files

- All Internet participants agree on many conventions called Internet standards . The most fundamental is the protocol suite referred to as the Transmission Control Protocol/Internet Protocol (TCP/IP) Although IP addresses are not assigned geographically (the way ZIP codes are), the first number identifies a region, the second a local area, the third a local net, and the fourth a specific computer. Computers that are permanently linked into the Internet may have a fixed IP address assigned, whereas users whose machines reach the Internet by dialing into an ISP or making a wireless connection only when needed, may get a temporary address that persists just during a session.
- for two people to communicate effectively, they must agree on the syntax and meaning of the or words they are using, the style of the interaction,a procedure for handling interruptions, and so onThe Hyper Text Markup Language (HTML) describes what the information should look like when displayed
