Principle 1 Get the System Users Involved, they are the most critical of the system. Not only will they give you great ideas, but this will help with buy in.
Principle 2 Use a Problem-Solving Approach, this should be the approach on all project using some variation of a problem solving approach.
Principle 3 Establish Phases and Activities
Principle 4 Document throughout Development
Principle 5 Establish Standards
Principle 6 Manage the Process and Projects
Principle 7 Justify Information Systems as Capital Investments
Principle 8 Don't be afraid to Cancel or Revise Scope
Principle 9 Divide and Conquer
Principle 10 Design systems for growth and change
Database systems can be either referential, flat or heiarchial.
1 Explain architecture of Distributed Database systems? Also, explain the reasons for building distributed database systems?
The key concepts covered in the Fundamentals of Database Systems 7th Edition include database design, normalization, SQL queries, transaction management, indexing, and data warehousing.
The relationships between database applications DBMS and databases is as follows: Databases can be simple or complex. simple databases can be kept in a Microsoft Excel spreadsheet or they can be maintained in a user generated Microsoft Access database which can be programmed to query certain data that has been entered into that database over a period of time. Microsoft Excel and Microsoft Access are also applications that are used to build databases that can be incorporated into DBMS or Database Management Systems. These systems can be extremely complex or they can be simple meaning that maintenance to these systems is not demanding. If the DBMS is complex it may require an entire team of technicians and in some cases engineers.The relationship between users, database applications, databases, and Database Management Systems can be simplified even further - Users can access a database that has been created with a database application to query managed data that is a part of a uniform Database management system.
What is object-oriented systems development
Database systems can be either referential, flat or heiarchial.

There are currently 3 general categories of data base management systems in use today:relational database systemsmultidimensional database systems (often referred as 'cubes')object oriented database systemsPrior to the success of relational database systems (early 80's) there were also hierachical database systems and network (aka CODASYL) database systems.

Two important historical contributions in database development and design are the development of the relational model by E.F. Codd in the 1970s, which introduced the concept of relational databases and structured query language (SQL), and the creation of the first commercial database management system (DBMS) by IBM called IMS in the 1960s, which laid the foundation for modern database systems.
It is easy to use, and already comes installed on many machines.However, it isn't a particularly powerful database. It might be used as a prototype, or for some small systems, but for professional development, it isn't the best option.It is easy to use, and already comes installed on many machines.However, it isn't a particularly powerful database.

The relationship between the information system life cycle and the database system development life cycle is that the informational systems help management entities to shift and move resources from one department to another easily by using a shared database system.
There are lot of Database Management systems that run on Linux, but MySQL and PostgreSQL seem to be the mostly used Database Management systems.
