This blog tries to relate the topics that are being blogged about. So lets try to relate all these things to get the big picture of them all.
Lets take a journey from the web services and we can move through the rest of the topics.Consider a user accessing a web page to download a picture. The web services starts from a client request to the server. So lets guess how this works.
The client sends a message which reaches the server. There can be many paths from client to server and the client must choose the optimal path. This is done by using path finding algorithms. The information will be stored in the networking devices. Proper data structures should be used to give the optimal path to the request from the client.
The web page from which the request starts will contain many components. Each component will have particular attributes and behavior. This can be easily established using Object Oriented Programming Languages. Here each component will be represented as an object.
Once the request reaches the server the web server will get the request and will forward it to the application server. This application server will be used to get the picture.
The picture will be stored in a database. The DBMS will abstract the application programs from the manner in which the data is stored in a database. There will be different data structures which will be used to retrieve the data efficiently. The most preferred data structures used here are indexes and trees(B+).
Database concentrates more on the data while DS concentrates more about organizing the data.
Anything which is getting stored will require a data structure. Hence the data structure will be an essential in a programming language like OOPS. The OOPs is related to RDBMS. Because the master tables can be represented by using the objects. There also exists OODBMS which purely depends on the Object orientation.
