The technical issue is: how is a data system organised, managed, and maintained?

One subset of data models is those that store concepts in the same hierarchical structure as the underlying database.

In order to create an effective data flow diagram, how should one proceed?

A database is to be designed for a college to monitor students' progress throughout their course of study. The students are studying for a degree (such as BA, M.Sc., etc.) within the framework of the modular system. The college provides a number of modules, each being characterized by its code, title, and credit value, module leader, teaching staff and the department they come from. A module is coordinated by a module leader who shares teaching duties with one or more lecturers. A lecturer may teach (and be a module leader for) more than one module. Students are free to choose any module they wish but the following rules must be observed: some modules require prerequisites modules and some degree programs have compulsory modules. The database is also to contain some information about students including their numbers, names, addresses, degrees they study for, and their past performance (i.e. modules taken and examination results). Draw an ER diagram for this database using as much of…

Where do relational, conceptual, and conceptual data modeling diverge?

Data flow diagrams may be classified as either "logical" or "physical." A data warehouse cannot function without MetaData.

What adjustments may be made to the standard database development life cycle's data administration at each step in order to offer high-quality, reliable systems more quickly?

The concept of data flow diagrams may be broken down into two distinct types, each of which has a distinct set of benefits and drawbacks. What makes MetaData such an essential component of a data warehouse?
