This blog entry will be about basic GIS definitons, usages and terms explained in my native language (Turkish). It is prepared under a full document so i would like to distribute it as is.
Coğrafi Bilgi Sistemleri Rehberi
CBS, konummsal ve coğrafik koordinat bilgilerinin ilişkilendirilebildiği verilerle çalışabilen ve bu verilere; toplama, saklama, değiştirme, sorgulama ve görüntüleme gibi işlemleri uygulayabilen, veri tabanı destekli bilgi sistemidir. Coğrafik Bilgi Sistemi (CBS), bilgisayar teknolojisi yardımı ile konulu harita/plan tabakalarının bir görsel veri tabanında yer almasından oluşan sistem olup, sistemin en önemli özelliği; onlarca bilgi tabakasına, paralel olarak kısa zamanda erişerek herhangi bir konuda sorgulama yapabilmesidir.

Definiton
Electronic Museum Guides are systems to provide audio, visual or textual content to museum visitors with or without user interaction during musuem visits.
Usage Areas
Electronic Museum Guides are used in every type of museum. Including open area museums.
Fee
Electronic Museum Guides may be provided by the museums with or without a fee. Some museums offer the systems with entrance ticket or promotional tickets.
Content Types
Museum Guides provides content to visitors in several forms
Audio Content
Textual Content
Visual Content including videos, animations and so on.
Content Alternatives
Electronic Museum Guides shall be operated to supply content in different languages and accents, with different voice alternatives like (Man/Woman/Child/Native Speaker/TV Speaker/etc.), with text, with age group specific content.
Content Alternating Mechanism
Electronic Museum Guides may alter their contents by user or operator selection; or may be provided by distinct different physical devices.
Extra Contents
Electronic Museum Guides shall include extra contents like ads, banners, sponsor links, and so on.
Electronic Museum Guides shall play the extra content with object triggering, time triggering, location triggering or action triggering mechanisms.
Tour Guiding Mechanism
Electronic Museum Guides may provide several options for tour guiding.
Self Motivated Tours : Visitor shall tour the museum on behalf.
Directed Tours : Visitor is directed by the system in a manner such that visitor can visit object by object section by section or theme by theme. This option can also be altered by restricting the time of visit.
Semi-Directed Tours : Visitor is directed by the system but he or she can break the sequence and can then join the sequence respectively.
Operating Alternatives
Electronic museum guides may be operated by several ways:
Touch/push buttonned systems will be operated by the visitor. Visitor will enter the code assigned to the object to the electronic museum guide and the related content is provided.
Location aware systems will semi automatically operate. They sense the location by several alternative technologies and provide the related content. If the sensing area is not narrow enough to detect every different object then the visitor will enter or select the content he or she wants.
Line of Sight Aware Systems will automatically operate. They sense the location and the target object and provides the related content. These systems may include an artificial intelligence that will meaure the visitor aims and interest areas and may provide shallower or deeper information for the object. These systems may need special technologies for target detection.
Interactive Electronic Museum Guides
Electronic Museum Guides can be interactive. The interactiveness may include
Short Messaging between visitors or museum staff
Souveniour Sales Integration
Voice Message Recording
Action, Presentation, Meeting Planning
Object/Content blogging
Conduct Survey
Collect Opinions
Measure Customer Satisfaction Survey
Museum Management Support Feautures
Electronic Museum Guides shall provide the museum management great statistics and reports. Which may include
Tour Statistics
Visitor Statistics
Visitor aims
Object Statistics
Opinions
Survey Results and statistics

Electronic museum guides provides great job when there is no human guiding the tour.
Today Handheld electronic museum guides provides rich content and became smarter; to attract audience.
Basic problem with the handheld devices are most of them are not location aware, hence they are not aware of the visitor's line of sight. Moreover most of them do not sense the user preferences.
Location awareness is a simple problem to solve, there are many possibilities now on market. If the museum guide guides the tour from start to end giving the directions it will enhance the visitors, since the tour will probably be a directed tour and the content is following the prior subjects.
Line of sight awareness will make the difference, you can provide the right content at the right place and at the right time. This will improve the visit in locations where many objects are available in a small area. Visitor can freely go on the tour without needing to enter the correct numbers assigned on the objects like in convansional systems. Furthermore by line of sight awareness you can detect the object or concept aim of the visitor; so that you may provide deeper information in relevant objects. This must also include some artificial intelligence. By this way you may offer the visitor other options listed or presented at the museum.
Interactive electronic museum guides are important for museum management. Interactive systems can conduct surveys, can establish special meetings or presentations, can assist souveniour sales, can alternate the content offered, can collect opinions. Moreover the users may want to blog their opinions on an object, section or museum in vocal form.
Interactive electronic museum guides may provide messaging between visitors and management. Which will improve the communication and management capabilities of the museum.
We at BYDS produced the Handheld Electronic Museum Guide System eCicerone with these arguments in our minds. We hope this will put the bar higher to make our competitors to reach.

"Management system" refers to the organization's structure for managing its processes - or activities - that transform inputs of resources into a product or service which meet the organization's objectives, such as satisfying the customer's quality requirements, complying to regulations, or meeting environmental objectives.
ISO 9001 is management standard that for any business type includinf, public administration, or government department.
Growth in the use of management systems generally has increased the need to ensure that laboratories can operate to a quality management system that is seen as compliant with ISO 9001 as well as demonstrate technical competency. Therefore, ISO 17025 was written to incorporate all the ISO 9001 requirements that are relevant to the scope of testing and calibration services as well as specifying the technical requirements for technical competence.
Testing and calibration laboratories that comply with ISO 17025 will also operate in accordance with ISO 9001.
BYDS provides labmania to maintain both standartds at a glance.

The Setup failed to read IisMimeMap table. The error code is -2147023550.
Before Microsoft SQL Server 2005 SP2 uninstalling Reporting Services could end up with this error. To get rid of it you should stop the Default Web Site on IIS.
This issue is reseoved with Micrososft SQL Server 2005 SP2.
P.S.: If you have changed the port number of Default Site on IIS when installing Reporting Services, before uninstallation you may need to change the port number back.
