We're trying to work out why the same SQL Script takes much longer to run within the Enterprise environment compared to the Development?
What makes matters worse is the development version is on a standard desktop (P4 1.8 256MB RAM) compared to the Enterprise version which sits on a dual Xeon with 1Gig of RAM.
Is is related to the SQL product or am I missing something here? :confused:
Hello,
I installed the SQL Server 2k EnterPrise version and developer version on the same version, and the developer version is an instance "Development".
How do I expose both of them to internet? Just open both of them to port 1433? And on the client side, just say IP and IP/Development? Do I need specific set up, will they conflict?
Thanks,
I am trying to modify a survey DB schema created by OOP(Object Oriented Programming) snobs who had their heads so far up their butts(in my opinion).
This is current schema created by them.
Diagram 1 (OOP snobs version)
http://us.f3.yahoofs.com/users/41a4fde6zcff655d9/a2ae/__sr_/2761.jpg?phsEJvBB3t1v7URD
Actually there aren't a several foreign keys as they are shown in the picture, but that's what they(OOP snobs) are doing to the table "Response". They are inserting question_collection_id and its name as well as question_id and its name to Response table. However, it was not ill-intended, "We just wanted to load the report quickly"(OOP snobs).
But I really recommend this schema, Because of its simplicity.
Diagram 2 (My version)
http://us.f3.yahoofs.com/users/41a4fde6zcff655d9/a2ae/__sr_/e890.jpg?phrEJvBBF0.lGY5Y
Yet I haven't proven that my schema will provide report just as quickly as OOP snobs' version. As mentioned earlier, since they don't have foreign key constraints accordingly, I do find quite number of discrepancy on values of "question" columns between "Question" and "Response" tables and "question_collection" columns between "question_collection" and "Response" table. I can provide schedule task to eliminate those problems. But I really prefer my schema than theirs. So far, I can explain mine is better just because of its simplicity and DBA's gut instinct. I'd like to hear Superior Expert's opinion which schema is better and why one is better than the other.
Attached is also zip files of schema images if you can't see them by those URL.
The BI Survey is the largest independent survey of BI technology users worldwide. (It used to be known as the OLAP survey, but has expanded to cover a broader array of BI technologies.) The survey analyzes people's buying decisions, BI implementation cycles and business results achieved.
The BI Survey is strictly independent --- they ask vendors like us to ask our customers like you to participate, but we don't have any other involvement --- except closely reading the results, of course. The Survey will send all participants a summary of the full survey results and place them in a drawing for ten $50 Amazon vouchers.
You can complete the survey on-line by following these links:

I am going into salary negotiationyearly review next month after my week off and I am trying to determine what to ask for. I am thinking another 10K and an extra week off would not be unreasonable, but I wanted to get some idea of what you guys think I should ask for in terms of pay.I have been developing software for seven years and I have been a dba for a little over five. I live in pricey northern Virginia. On a fairly regular basis I do about 55 to 60 hour weeks. On my DBA team, I am the only one who can handle both development and production tasks. The others are strictly developers. Although I have been relieved of most of my customer support tasks by our newbie, the customer support manager still brings the nastier bits to me. It is my perception that the more complex tasks get assigned to me. I get told on a regular basis that I am the best dba this place has ever had and other embarrassing accolades are regularly thrown my way. After a year, other than my boss I am the dba that has been here the longest in high turnover high burnout company. This year as we try to move to a SAP model, it looks like we will be going to 24/7 support on a disaster recovery model I am designing and implementing, so I guess I am getting the pager.So how much money should I be asking for?you can PM me with a number if you want.

I have surveys that I need to add weights to and was wondering if there was a way to convert the contents of a column.
select empid, ans_for_ql,
(if ans_for_ql = A then 0, B then 3, C then 5) as weightscore,
ans_for_q2,
(if ans_for_q2 = A then 8, B then 4, C then 2, D then 1, E then 0) as weightscore
Here is what the table looks like:
empid | Ans_for_Q1 | Ans_for_Q2
1001 A C
1002 B E
And these are the possible answers and what they need to be converted to:
Weights for answers to Question1
Q1_A = 0
Q1_B = 3
Q1_C = 5
Weights for answers to Question2
Q2_A = 8
Q2_B = 4
Q2_C = 2
Q2_D = 1
Q2_E = 0

Hi,We are a systems research group at the Computer Science departmentatRutgers University, and are conducting a survey to understand detailsabout network, systems and database administration. We hope that thisinformation would help us recreate a realistic environment to helpresearch in 'systems management'.We request network, systems, and database administrators to take thissurvey. As an incentive, all surveys completed in their entirety willbeentered into a drawing of a number of $50 gift certificates (fromAmazon.com).We hope you have a few minutes to take the survey which is located at:http://vivo.cs.rutgers.edu/administration_survey.htmlResearch in our group:The goal of our research is to improve the overall availability andmaintainability of services. Since administrators form an integral partof these services, a key aspect of this work is to build environmentsand tools that ease the task of service administration. In particular,environments which would help administrators know how their actionsmight impact the real service (before performing them for real), webelieve would be useful in preventing inadvertent actions. This surveytries to understand the existing environments, what administrators docurrently to test the 'validity' of their actions, and the difficultiesthey face in doing so. The two specific systems we are looking at arenetworks and databases, as we believe these are important components ofmany services.If you have any questions regarding this survey or our work, feel freeto email us:Fabio Oliveira (fabiool at cs || rutgers || edu), orKiran Nagaraja (knagaraj at cs || rutgers || edu)Thanks for your time,Fabio OliveiraPhD student, Vivo Research Group (http://vivo.cs.rutgers.edu)Rutgers University

View 2 Replies View RelatedI've written several survey systems in which the majority of the questionshave the same or similar responses (Yes/No, True/False, scale of 1 - 5,etc).But this latest survey system I'm working on has 8-10 sections, with avariety of question attributes and answer scales. Some items have just adescription and require a Yes/No answer, others have a description and anactive status and require a Yes/No and price answer, some require a comment,etc.Rather than build a separate response table for each survey section, I wasthinking of building one generic response table, and trying to force allsections to fit by adding columns - some of which won't apply to some items.Like this:Survey Category (will apply to all items)Survey Section (will apply to all items)Item Description (will apply to all items)Item YN (will apply to all items)Item Price (will apply to about 10% of the items)Item Points (will apply to about 10% of the items)Item Active YN (will apply to about 10% of the items)Item Fail YN (will apply to about 10% of the items)Item Comment (will apply to about 10% of the items)For instance, in the structure above the field "Item YN" would representmultiple types of answers: is the item in use?, is the item in place?, isthe item given away for free?, is the item on display?, etc. Basically,anywhere a Yes/No answer is used.The advantage is one source table (rather than 8) for storing answers, andit might be easier to query and report on.The disadvantages I see are 1) it's more difficult to understand the meaningof the responses when the answer field is named Item YN, and 2) you have anon-normalized table that's difficult for a 3rd party to understand.If I have the questions and responses in separate tables, I'll use nameslike "ItemComplimentaryYN" and "ItemUsedYN" depending on the question. It'seasier for others to learn the data.I actually don't like the "generic" approach, and probably won't use it, butI figured I'd try to get some input from others who've written surveysystems.Thanks

View 11 Replies View RelatedI am working on a survey system with another DB Engineer.Our current design includes 1 table per Question Type (Numeric, Boolean, Text), Response values are tightly coupled based on data being entered, to keep things simple assume there are only 6 tables in this this system (1 for each Question Type to define the "rules" of the data entered, and 1 for each Response collection).He is a former .Net programmer and has been talking with the .Net guys on the project and he is proposing that we abstract our Question Types to use one table and store the Input Values all as nvarchar(max).This obviously simplifies the DB design and reduces the amount of work I will need to do so I should be all for it. I guess I am a little concerned that we are no longer tightly coupling the data types and essentially leaving all the validation up to the application. Also should I be worried that a bunch of bit data will be stored as 1/0 in an nvarchar(max) column?Thanks,-John

My Questions : How can I store data if questions is multiply answers (checkbox type) ?What is best way ?
I am a developer and I have a problem trying to design a system to
manage data coming from web surveys. On average each subject will take
part in more than one survey and each survey may potentially have 100+
questions.
I am focusing here only on the table(s) that will hold the survey
data.
I'm thinking about having a wide table storing each question in the
survey(s) as a column against the subjects. My main concerns with this
approach:
- the "yuckiness" and potentially other performance issues(?)
associated with a table with 100s of columns
- the 8kb size limit per row (unlikely to touch it, but possible)
- 1024 column limit (unlikely to touch it, but possible)
Another approach obviously is to have a single table where we have, in
a simplified version, 3 columns: person_id, question_id and data/
answer. The problem with this is that the "data" column will have to
accommodate
all types of data, from bits to varchars, and that field validation
seems now impossible jeopardizing data integrity, and most
importantly, you can't easily work with the data in filtering/
reporting etc.
What do knowledgeable designers come up with in this case? Can someone
point me in the right direction?
Basically our cube contains two different Facts:
- Sales Volume: Information about sold articles to a customer incl. Selling date
- Survey: irregular answered survey questions about customers incl. date of answer
and three Dimensions:
- Customer
- Date
- Survey Answer: Information about possible Answer values (e.g. Yes / No)
Relations:
Fact: Sales Volume ------> Dim: Customer <------ Fact: Survey ------> Dim: Survey Answer
'--------------> Dim: Date <----------------'
We would like to be able to determine the aggregated sales volume (sum) of a customer for a specific period depending on the latest survey answer within this period.
For example:
Selected Time period: Jan - Jul 2015
Sales Volume Customer X - Jan - Jul 2015: 1000 Litres
Sales Volume Customer Y - Jan - Jul 2015: 500 Litres
Surveys answered:
15th Jan 15: Customer X, Survey Question A: Yes
2nd Mar 15: Customer X, Survey Question A: No
20th Apr 15: Customer X, Survey Question A: Yes
10th Feb 15: Customer Y, Survey Question A: Yes
20th Jul 15: Customer Y, Survey Question A: No
Latest survey answer (Jan-Jul) Customer X, Question A: Yes
Latest survey answer (Jan-Jul) Customer Y, Question A: No
Excel Pivot should show something like this:
Question | Latest Answer: Yes | No |
------------------------------------------------------------------------------------
A | 1000 Litres | 500 Litres |

I am replacing the corporate SQL Server at work. The new server will have 6 striped disks of 160G with about 4G of RAM. The current SQL Server currently has two instances which run web applications and a small database warehouse about 6G. Analysis Services is also installed.
Due to a couple of new apps being added to the server and the SQL Server 2000 enterprise license we acquired, i was thinking of adding 2 more instances so that the applications can be independently managed in terms of restarting the SQL Server. I also would like to permanently fix the memory settings on each instance to give more resources to more important applications. The log and data files would also be spilt onto 2 separate hard disks. i understand there are implications on performance such as CPU etc. Is it normally advisable to have more than 1 or 2 instances ? Most of the applications are not very CPU intensive. What other implications or performance issues would l have ?
We will be creating a moderately high-volume OLTP database application that needs 24/7 availability. We are planning to offload OLAP processing to a second copy of the system. We will be using SQL Server 2005.
I originally planned to set the second server up with SQL Server 2005 mirroring to cover the 24/7 availability requirement, with the idea that we could also do OLAP reporting off of the mirrored copy of the database. But I've gotten some indications that a mirror database is offline and not available for querying. So I figured I would use transactional replication to keep the OLAP database current. Now I am wondering if I need to use mirroring at all, or if I should just use transactional replication on the entire database and swap to the replicated database if the production server crashes.
What is everyone's opinion?
Replication only, for both OLAP reporting and failover?
Mirroring to one database for failover, with replication to a another database for OLAP reporting?

Solutions are easy. Understanding the problem, now, that's the hard part
We are designing a SQL Server architecture that will need to handle a lot of inserts and many users.
We are not sure what approach to take if we should build a distributed server architecture with a Single Master SQL and many Slave SQL Servers.
Or if we should get a really powerful machine with many processers to handle all the connections.
We project we will have about 5,000 Inserts per sec coming from 500,000 users.
What do you think or what has your previous experience been with handling many inserts and few reads for many users?
Thank you
Hi there,
My question is more "architectural" than technical.
One of our standard is to systematically enclose the code of our stored proc within a TRY/CATCH block.
What is your point of view?
Should a TRY/CATCH be included even for simple operations?
Are there any drawbacks?
Thanks!
EDIT: Thanks for your input.
I've implemented a solution with application, database and report server on seperate machines. The application is a web app and is Internet facing. What is the best method for executing reports on the RS server that are initiated from the web server? Using URL access requires a login or anonymous access neither of which are desired. Web services works but I loose access to the toolbar. Is there some other way to pull this off where I can let the public access reports and give them access to the toolbar?
Thanks.
In a situation where one may have a single master SQL Server that ultimately needs to communicate information back down to 1000's of downstream servers, what is the recommended architectural approach?
It doesn't feel right to have to add 1K-5K routes to the master SQL Server. Is there a way to have the dowstream servers "broadcast" their existence to the master, so that new servers can be added and updates can happen seamlessly? Does this fall into a pub-sub scenario or is there a better way? And, if so, how to ensure an open conversation (so that one server doesn't miss information that all the other servers received)? Should the master dynamically create routes or better to rely on an open conversation initiated by the downstream server?
Hi Everybody ,
Could Anybody please explain in detail about the Achitecture of Sql server reporting services?
1) What a Report processor in detail and what it does?
2) What is the exact work of Extensions?
3)What is SOAP and WMI?
