2. Database design - Wikipedia

   en.wikipedia.org/wiki/Database_design

   Database design is the organization of data according to a database model. The designer determines what data must be stored and how the data elements interrelate. With this information, they can begin to fit the data to the database model. [1] A database management system manages the data accordingly.

3. Query plan - Wikipedia

   en.wikipedia.org/wiki/Query_plan

   A query plan (or query execution plan) is a sequence of steps used to access data in a SQL relational database management system. This is a specific case of the relational model concept of access plans. Since SQL is declarative, there are typically many alternative ways to execute a given query, with widely varying performance.

4. Systems development life cycle - Wikipedia

   en.wikipedia.org/wiki/Systems_development_life_cycle

   A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

5. Database administration - Wikipedia

   en.wikipedia.org/wiki/Database_administration

   The process of creating a new database can consist of hundreds or thousands of unique steps from satisfying prerequisites to configuring backups where each step must be successful before the next can start. A human cannot be expected to complete this procedure in the same exact way time after time - exactly the goal when multiple databases exist.

6. Query optimization - Wikipedia

   en.wikipedia.org/wiki/Query_optimization

   Query optimization is a feature of many relational database management systems and other databases such as NoSQL and graph databases.The query optimizer attempts to determine the most efficient way to execute a given query by considering the possible query plans.

7. Database normalization - Wikipedia

   en.wikipedia.org/wiki/Database_normalization

   Database normalization is the process of structuring a relational database in accordance with a series of so-called normal forms in order to reduce data redundancy and improve data integrity. It was first proposed by British computer scientist Edgar F. Codd as part of his relational model .

8. Data architecture - Wikipedia

   en.wikipedia.org/wiki/Data_architecture

   The technology plan is focused on the actual tangible elements to be used in the implementation of the data architecture design. Physical data architecture encompasses database architecture. Database architecture is a schema of the actual database technology that would support the designed data architecture.

9. Business systems planning - Wikipedia
