Study Notes
Database Environment and Development Process
- A database is an organized collection of related data, logically structured.
- Legacy systems are older systems containing poor quality data.
- Program-data dependence is caused by file descriptions stored within each database application, data descriptions within programming code, or by data cohabiting with programs.
- File processing systems often result in unplanned duplicate data files. Data is not always non-redundant.
- Relational databases establish relationships between entities via common fields in a relation.
- A user view is a logical description of a portion of the database.
- Database standards are set by the Database Administration function.
- ODBC is a tool non-programmers can use to access database information.
- Redundant data is NOT an advantage of database systems.
- Database failures are mainly due to issues with database administration (not planning, budget, or hardware).
- A constraint is a rule that cannot be violated by database users.
- In file processing environments, descriptions and logic for accessing data reside within application programs.
- Database technology's objectives include providing greater independence between programs and data, managing complex data types, and enabling decision support applications.
- A workgroup is a small team collaborating on a project.
- A workgroup database is stored in a central device (like a server).
- The need for consensus on data definitions is a cost/risk of organizational conflict in database approaches.
- The SDLC (Systems Development Life Cycle) is a traditional methodology to develop, maintain, and replace information systems.
- The SDLC phase where data attributes, categories, and relationships between entities are defined is the analysis phase.
- The phase where database processing programs are created is implementation.
- Database organization on storage media occurs during the implementation phase.
- Database analysts do not focus on determining requirements for database components.
- The three-schema approach includes internal schemas.
- The ERD (Entity-Relationship Diagram) is the most common RDMS data model notation.
