Distributed databases allow data to be stored across multiple computers or sites connected through a network. The data is logically interrelated but physically distributed. A distributed database management system (DDBMS) makes the distribution transparent to users and allows sites to operate autonomously while participating in global applications. Key aspects of DDBMS include distributed transactions, concurrency control, data fragmentation and replication, distributed query processing, and ensuring transparency of the distribution.
This document summarizes a workshop on data integration using ontologies. It discusses how data integration is challenging due to differences in schemas, semantics, measurements, units and labels across data sources. It proposes that ontologies can help with data integration by providing definitions for schemas and entities referred to in the data. Core challenges discussed include dealing with multiple synonyms for entities and relationships between biological entities that depend on context. The document advocates for shared community ontologies that can be extended and integrated to facilitate flexible and responsive data integration across multiple sources.

DSBW Final Exam (Spring Sementer 2010)
1. Problem 1: UX Model (20%)
DSBW – Final Exam June 14, 2010 You are requested to design the UX Model of part of the functionality for a “light”
version of Twitter called Chirper (to chirp ≈ to tweet)
Instructions:
Home
• You can’t use any notes
• In case of doubt, make an assumption and document it clearly After logging in the main page of Chirper (not shown here), the user comes into
• Grades will be published on June 29. Revision will be on July 1 from 11:30 to her "Home", which shows, among other things, messages (chirps) sent by she as
13:00 at the room Omega-120. well as the people she follows, in reverse chronological order (See the figure on
the left). The last message sent by the logged user (Latest) is always displayed
under the form to add new chirps.
From this view, the user can perform the following actions:
Click on "Go Home": The system returns this very same view.
Click on "Profile": The system returns the profile for the logged user (See
Profile below).
Click on "Logout": The system returns the main page of Chirper.
Fill the form "What's in your beak?" and click on the button "Chirp": The
system returns the current view with the resulting update.
Click on the number of chirps (e.g.137) sent by the logged user: The system
returns the chirps sent by that user (See User Page below).
Click on the number of users followed by the logged user (e.g. 17): The
system returns the people followed by the user (See People below).
Click on the number of users that follow the logged user (e.g. 32): The system
returns the people that follow the user (See People below).
Fill the form "Search topics in chirps" and click on "Search", or click on one
out of the 10 "trending topics" (p. ej CNBLUE), or click on a topic reference
(hashtag) included in the text of a chirp (e.g. #PrimeFaces in the 3rd chirp):
The system returns the very same view but showing the messages in Chirper
that contain that topic (And "Home" is replaced by "Real time results for
selected_topic")
Click on the username of the user who has sent one of the displayed chirps
(e.g. "lemire"), or click on the username reference (preceded by "@") included
in the text of a chirp (e.g. "addis" in the 4th chirp): The system returns the
chirps sent by the selected user (See User Page below).
Click on "See more chirps": The system adds more (former) chirps to the
displayed list.
2. Click on the username reference (preceded by "@") included in the text of a
chirp (e.g. "pfcdgayo" in the 1st chirp): The system returns the very same view
but showing the information corresponding to the selected user.
Click on "See more chirps": The system adds more (former) chirps to the
displayed list.
People
The system displays information related to the people who are followed by a given
user (as is the case of the figure shown below, where the people followed by
Lemire appear), or the people who follow that user (if this were the case, "lemire
has 964 followers" would replace "lemire follows ...").
From this view, the logged user can perform the following actions:
Click on "Go Home": The system returns to the logged user’s Home.
Click on "Logout": The system returns the main page of Chirper.
Click on the username of a person (e.g. "dlowd" or, even, "lemire"): The
system returns the chirps sent by the selected user (See User Page).
Click on “follow” (or “unfollow”) for a certain person: The system records that
the logged user wants to follow (unfollow) that person and returns the same
view with the resulting update.
User Page
Click on “See more people”: The system adds more people to the displayed
The system displays the chirps sent by the selected user (in reverse chronological list.
order) as well as information from her profile (top right, see figure above). From
this view, the user can perform the following actions:
Click on "Go Home": The system returns to the logged user’s Home (See
Home above).
Click on "Logout": The system returns the main page of Chirper.
Click on "unfollow" (or "follow"): The system perform the requested action an
returns the same view with the resulting update (If the displayed user is also
the logged one, then neither “unfollow” nor “follow” show up)
Click on the number of users followed by the displayed user (e.g. 61): The
system returns the people followed by that user (See People below).
Click on the number of users that follow the displayed user (e.g. 964): The
system returns the people that follow that user (See People below).
Click on a topic reference (hashtag) included in the text of a chirp (e.g.
#publishing in the 2nd chirp): The system returns a view similar to Home (See
above), but showing the messages in Chirper that contain that topic (And
"Home" is replaced by "Real time results for selected_topic")
3. Profile Problem 2: Internal design with WAE and Patterns (20%)
The system provides a form to change the logged user’s profile (see figure below).
The form fields contain initially the current data recorded in the system. All form Do the internal design corresponding to the UX Model provided. That includes:
fields are optional and can be erased/left blank if desired. In addition, the user can 1. The complete class diagram of the internal design of the Presentation Layer

corresponding to the interaction scenario shown in the next page.
Assume that the screens and functionality described refer to those that can be
seen/executed by a user that has already logged into the system. A user can rate
a movie more than once, but the system records only the last assessment
