Suggestion: Create a Database Design Forum

I recommend the creation of a new forum dealing exclusively with database design questions, such as setting Primary Keys, Unique constraints, Check constraints, Indexes, schema-creation scripts, etc. There is no forum devoted exclusively to this topic now and I feel it would be very helpful to the user community. It would certainly make searching for answers to design questions much easier.

1. How to create a relational model certainly IS relevant to Oracle, which is a RELATIONAL DBMS.Oracle also supports data warehousing (star schema designs), network/hierarchical designs, object-relational designs - or pretty much any data model that you may come up with. Calling it just a relational DBMS is incorrect.
2. Your point that logical models are independent of specific technology is correct. What you're missing is that if a specific technology makes use of a certain foundational body of knowledge, that knowledge is a legitimate topic for a forum whose users use that specific technology.That is putting the cart in front of the horse IMO.
I would rather see data modeling and logical database design being done in a way that is untainted with specific vendor implementations and technology used. There needs to be a clear line dividing the design from the implementation. If not, then design decisions can (and will) be made based not on the correct logical data modeling principles, but whether it can be "handled" by the technology. A design that is tainted like that, will always be less than optimal (especially as technology is continually evolving and changing).
An OTN forum for database design will invariable be tainted with Oracle technology - and instead of learning sound data modeling fundamentals, a warped view of data modeling will be conveyed. Where doing abc will be acceptable (when it is not), because Oracle has feature xyz that can make the flawed design work (in a fashion).Excellent points. I think (or at least hope) such a forum would attract some number of pure theorists to straighten out the view. This might make for a lively forum, and might actually influence the real products, and might even get the cart on the right side of the horse.
Hmmm, I guess I do sound hopelessly optimistic.

Database design (ERD )for Inventory Management System

Dear All,
I am going to develop a simple Inventory Management System software using C# .NET for my learning. After searching different forums, many people have suggested to first create a database design for the software. I want a database design, in short, an ERD
diagram for simple Inventory Management System which shows proper entities(tables), attributes and relationship between entities.
It would be highly helpful for me as I am newbie to C# and databases.
Thanks,

Dear Rebecca,
Thanks for you suggestions.
As I am going to develop IMS for learning purposes so I think I wouldn't need to go in detail regarding Customer name and addresses. However, I am still thinking of adding country attribute in customers' table which I think will be helpful to sort out customers.
What's the difference between a purchase and an order? They're usually the same thing, which doesn't mean you're
wrong, but what are you picturing here? Purchase entity will be used to keep record of purchases you made and an order entity will be used to keep record of orders that cutomers placed.
Pricing:
Any order system needs to manage two very distinct bits of data that are easy to confuse. The price in the Product entity is the current
price. The price in the Order entity is the selling
price. Not at all the same thing--current price is almost certainly going to change over time. Selling price won't.
Does it mean that I'll change the price attribute for product to current_price and add selling_price to order table which will help to keep record of price at the time of order?
Why did you include a quantity field in the Products table? Is it meant to represent stock on hand?
Yes you are right. It represents stock in hand.
Could you please recheck the entities relationships as I am not confirmed whether these are correct or not?
Thanks,
momersaleem

Database design to support parameterised interface with MS Excel

Hi, I am a novice user of SQL Server and would like some advice on how to solve a problem I have. (I hope I have chosen the correct forum to post this question)
I have created a SQL Server 2012 database that comprises approx 10 base tables, with a further 40+ views that either summarise the base table data in various ways, or build upon other views to create more complex data sets (upto 4 levels of view).
I then use EXCEL to create a dashboard that has multiple pivot table data connections to the various views.
The users can then use standard excel features - slicers etc to interrogate the various metrics.
The underlying database holds a single days worth of information, but I would like to extend this to cover multiple days worth of data, with the excel spreadsheet having a cell that defines the date for which information is to
be retrieved.(The underlying data tables would need to be extended to have a date field)
I can see how the excel connection string can be modified to filter the results such that a column value matches the date field,
but how can this date value be passed down through all the views to ensure that information from base tables is restricted for the specied date, rather than the final results set being passed back to excel - I would rather not have the server resolve the views
for the complete data set.
I considered parameterisation of views, but I dont believe views support parameters, I also considered stored procedures, but I dont believe that stored procedures allow result sets to be used as pseudo tables.
What other options do I have, or have I failed to grasp the way SQL server creates its execution plans and simply having the filter at the top level will ensure the result set is minimised at the lower level? (I dont really want the time taken for the dashboard
refresh to increase - it currently takes approx 45 seconds following SQL Server Engine Tuning Advisor recommendations)
As an example of 3 of the views,
Table A has a row per system event (30,000+ per day), each event having an identity, a TYPE eg Arrival or Departure, with a time of event, and a planned time for the event (a specified identity will have a sequence of Arrival and Departure events)
View A compares seperate rows to determine how long between the Arrival and Departure events for an identity
View B compares seperate rows to determine how long between planned Arrival and Departure events for an identity
View C uses View A and view B to provide the variance between actual and planned
Excel dashboard has graphs showing information retrieved from Views A, B and C. The dashboard is only likely to need to query a single days worth of information.
Thanks for your time.

You are posting in the database design forum but it seems to me that you have 2 separate but highly dependent issues - neither of which is really database design related at this point. Rather you have an user interface issue and an database programmability
issue. Those I cannot really address since much of that discussion requires knowledge of your users, how they interface with the database, what they use the data for, etc. In addition, it seems that Excel is the primary interface for your users
- so it may be that you should post your question to an excel forum.
However, I do have some comments. First, views based on views is generally a bad approach. Absent the intention of indexing (i.e., materializing) the views, the db engine does nothing different for a view than it does for any ad-hoc query.
Unfortunately, the additional layering of logic can impede the effectiveness of the optimizer. The more complex your views become and the deeper the layering, the greater the chance that you befuddle the optimizer.
I would rather not have the server resolve the views for the complete data set
I don't understand the above statement but it scares me. IMO, you DO want the server to do as much work as possible since it is closest to the data and has (or should have) the resources to access and manipulate the data and generate the desired
results. You DON'T want to move all the raw data involved in a query over the network and into the client machine's storage (memory or disk) and then attempt to compute the desired values.
I considered parameterisation of views, but I dont believe views support parameters, I also considered stored procedures, but I dont believe that stored procedures allow result sets to be used as pseudo tables.
Correct on the first point, though there is such a thing as a TVF which is similar in effect. Before you go down that path, let's address the second statement. I don't understand that last bit about "used as pseudo tables" but that sounds more
like an Excel issue (or maybe an assumption). You can execute a stored procedure and use/access the resultset of this procedure in Excel, so I'm not certain what your concern is. User simplicity perhaps? Maybe just a terminology issue? Stored
procedures are something I would highly encourage for a number of reasons. Since you refer to pivoting specifically, I'll point out that sql server natively supports that function (though perhaps not in the same way/degree Excel does). It
is rather complex tsql - and this is one reason to advocate for stored procedures. Separate the structure of the raw data from the user.
(I dont really want the time taken for the dashboard refresh to increase - it currently takes approx 45 seconds following SQL Server Engine Tuning Advisor recommendations)
DTA has its limitations. What it doesn't do is evaluate the "model" - which is where you might have more significant issues. Tuning your queries and indexing your tables will only go so far to compensate for a poorly designed schema (not that
yours is - just a generalization). I did want to point out that your refresh process involves many factors - the time to generate a resultset in the server (including plan compilation, loading the data from disk, etc.), transmitting that data over the
network, receiving and storing the resultset in the client application, manipulating the resultset into the desired form/format), and then updating the display. Given that, you need to know how much time is spent in each part of that process - no sense
wasting time optimizing the smallest time consumer.
So now to your sample table - Table A. First, I'll give you my opinion of a flawed approach. Your table records separate facts about an entity as multiple rows. Such an approach is generally a schema issue for a number of reasons.
It requires that you outer join in some fashion to get all the information about one thing into a single row - that is why you have a view to compare rows and generate a time interval between arrival and departure. I'll take this a step further and assume
that your schema/code likely has an assumption built into it - specifically that a "thing" will have no more than 2 rows and that there will only be one row with type "arrival" and one row with type "departure". Violate that assumption and things begin to
fall apart.  If you have control over this schema, then I suggest you consider changing it. Store all the facts about a single entity in a single row.  Given the frequency that I see this pattern, I'll guess that you
cannot. So let's move on.
30 thousand rows is tiny, so your current volume is negligible. You still need to optimize your tables based on usage, so you need to address that first. How is the data populated currently? Is it done once as a batch?  Is it
done throughout the day - and in what fashion (inserts vs updates vs deletes)? You only store one day of data - so how do you accomplish that specifically?  Do you purge all data overnight and re-populate? What indexes
have you defined? Do all tables have a clustered index or are some (most?) of them heaps?   OTOH, I'm going to guess that the database is at most a minimal issue now and that most of your concerns are better addressed at the user interface
and how it accesses your database. Perhaps now is a good time to step back and reconsider your approach to providing information to the users. Perhaps there is a better solution - but that requires an understanding of your users, the skillset of
everyone involved, what you have to work with, etc. Maybe just some advanced excel training? I can't really say and it might be a better question for a different forum.
One last comment - "identity" has a special meaning in sql server (and most database engines I'm guessing). So when you refer to identity, do you refer to an identity column or the logical identity (i.e., natural key) for the "thing" that Table A is
attempting to model?

Good database design and modelling books

Hi ,
I need to work on designing a database from the scratch by creating logical database design and then physical database design.I'm new to database design.
Can someone please point me to some good database design and modelling related books /tutorials.
Regards,
Bharath.

Hi Girish Thanks for the information.
I would definitely look into this book later.
I don't mind paying any amount of money,if that book gives me the knowledge I want.
As this book is international edition,for shipping it is taking 8-10 business days and by that time I need to complete designing my database and probably I might need to some other book.
Is this a school assignment? I hope so. Referring back to your opening statement "I need to work on designing a database from the scratch by creating logical database design and then physical database design.I'm new to database design." I can only say that database design is a very big subject. If you are starting from a position of no knowledge at all, I'm afraid there is nothing that is going to give you the knowledge you need in the time frame you have. I will say you need to start by learning the rules of Data Normalization. Make your logical design Third Normal Form. Good can be your friend. There is actually a pretty good write-up on Data Normalization on Wikipedia.

Form created with Livecycle Designer with a SQL database - do you need LiveCycle Forms installed?

Hello,
I'm REALLY hoping someone here can help me, I have spent over four hours on the phone to Adobe in the last 3 days and I'm getting no where what-so-ever. I can't even find out where /how to complain about it! (but thats another story)
Here's my situtation:
I work for a company with approx 140 staff. On one computer, we have Adobe Livecycle Designer ES installed, and we have used that program to create a form which has a link to a SQL database.
The link in this form doesn't work on the other computers which has the basic (free) Adobe Reader. From doing research within these forums
, I have found that the form will not work on other computers unless they have Adobe Livecycle forms installed on their machines.
What I need to know (and what they cannot seem to tell me when I call), is two things:
Is it correct that in order to use a form created in Livecycle Designer which has a link to a SQL database, that the machine must have LiveCycle forms installed?
How much does Adobe LiveCycle Forms costs?
PLEASE, if you can answer this question, I would REALLY appriciate it....
Thank you!

I presume you are asking if you need Livecycle Forms ES? Forms ES is a component of the livecycle software suite intended as a document service which will be installed on a server within the organisation. A couple of things this document service can do is to render XDP into multiple formats (PDF, html, etc.), execute script server side (for example the database connection) on behalf of the client (reader, etc.), integrate with backend components, etc. So no you do not install this on each client.
For database connections to work, you either have a server with Forms ES installed which can connect on each clients behalf (ie. Client->Forms ES Server->Database), or you have a reader-extended PDF to allow connections to be use in the free basic Reader (i.e. direct calls to the database or using web service calls to your own database components). However, reader-extended pdf would probably require Reader Extensions ES component installed on a server (you once off extend your developed pdf through this and then hand it out to each of the end users). Not sure if the Acrobat Reader extensions will cover this functionality since I have not tried that. I dont think it does. Otherwise you would need full acrobat on each client.
How much database integration is your form actually doing at the moment? read only? Full access? And how many clients do you expect to hit your database? Depending on what you need the form to do, there is always the option to try and build the integration yourself. Do simple http submits from the browser (hosting reader as a plugin) to some component somewhere which in turn hits your database. Wouldnt require additional licensing but alot more development work.
As for cost for the various components, thats a question only Adobe can answer for you since they all sit squarely in the enterprise space and licensing for that is not as simple as off the shelf products.
Maybe someone else has a view on it or has an alternative.

Request time out when creating content database

Hello,
my problem is, that i cannot create a SharePoint content database via the central administration.
My Setup is the following:
SharePoint Server 2013 Enterprise Farm
1x Applikation Server/WFE (Windows Server 2012 SP 1)
1x Database Server MSSQL Server 2012 (Windows Server 2012 SP 1)
1x TFS 2013 (Windows Server 2012 SP 1)
all of them are hosted in the same Hyper-V Environment. It is not the fasted Hyper-V Environment existing on planet earth.
The weirdest part of the problem is, i am able to create a content database via powershell.
I am running in some kind of time out issue related to the IIS and CA of that Applikation Server.
Here is the ULS Log from the failling content database creation via CA

The fact that i am able to create a content database through powershell sorts out permissions problems. I am certain of that because the w3wp.exe and the powershell.exe used for both creations were run under the same user.
The timeout always happens aroud 120 seconds after i started the creation. The creation via powershell takes about 3,5 minutes.
Here for the folks that ask me, why i haven't asked google or bing or some other search engine.
I tried the solutions suggested here
http://www.sharepointpals.com/post/Error-while-Creating-Web-Application-through-Central-Administration , here
http://anthonyspiteri.net/sharepoint-2010-web-ui-timeout-creating-web-application-quick-fix/ and here
http://blogs.ibs.com/Duane.Odum/Lists/Posts/Post.aspx?ID=33
which i thought pointed me to the right solution.
But those post unfortunatly didnt worked out.
I also tried to alter the web.config files (i know that isn't recommended or supported, but it didn't change anything so those are back to normal as well)
So here are my question:
Can you guys help me solve this issue?
Are there any other places where timeouts can be managed or defined?
P.S.: I am new to using this forum. so pls don't crucify me for doing a mistake.
P.S.S: My english is very poor also :D
With best regards
Simon

Be careful with settings like these because there may be a much deeper issue at hand. I have had an issue with a customer that manifests itself as a timeout on a site collection. It was very hard to track since it didn't happen frequently. We engaged Microsoft
Support to find out the root cause but all they could point at is a general network issue that pertains to authentication. After digging deeper, we found out that the network issue was caused by a saturated network connectivity to the domain controller that
impacts a site collection when the database is making an authentication call. Keep this solution as more of a quick fix but be sure to conduct a deeper investigation of the real root cause

Lost Adobe Create Suite 4 Design Premium for Windows disk #2

Hi, I have the Adobe Create Suite 4 Design Premium for Windows and have lost the Application disk #2 and cannot reinstall this on my new laptop. I have the licenses and the rest of the disks. I have called Adobe and they no longer support CS4. They suggested I try to find someone who has the software and get a copy of disk 2. Can some please help, I don't want to upgrade to CS5

>suggested I try to find someone who has the software and get a copy of disk 2
I am surprised by that... my understanding (albeit poor) of copyright is that you are allowed to make a copy of a disc for your own personal backup storage
That does not include making a copy to give to anyone else

Welcome to the forum...
Can you be a little more specific in what you're asking? Creating a database is something a DBA normally does, this has nothing to do with how a page in .Net might look...
You are probably looking for ways to create tables within the database to support that page.
Create Tables is very easy, but this is dictated by the Functional and Technical Design of your application. Simply showing a page from the application is not enough information. You would need to look at the Functional and Technical Design to know which tables (and what kind of tables) to create.
There is no "do this" answer with the information you supply.
Good Luck!

Excellent product. Pretty impressive. Gorgeous diagrams and sophisticated reports. Loved the myriad of navigation ways and non-obtrusive modeless dialogs. Very easy to use!
Keep the good work up.

Creating a Database in Apex

Hello,
I'm new to the forum and new to Apex, but it's been requested of me to create a database using Application Express.
I already designed a database in Access 2007, but am having a lot of difficulty in migrating that schema to Application Express.
I'm looking for solid resources that can take me step by step through the process of creating a database, but all the videos I've seen online aren't specifically for database creation.
Can anyone assist?
Thanks,
Derek

Database design for share market

Hi One and All,
I have a query regarding, design of New database....
Right now I joined as a Database administrator as a fresher, my superior has given me one assignment i.e. I have to create a sample database on Share market. As per his requirement the tables should be Issuer table, Security table, Broker table, INvestor table, Account table, Order table, Tradeing table. He said that I have to prepare the fiellds for this tables and relation ships and whole database structure.... I can prepare relations ships and database structure but the problem is, I don't know how the stock market is really works. If any body help me in this issue I am very thank full to him.
I need just the table feilds, if I get this rest of job i wil do by studying the subject of share market.
Thank You

Hi,
As per Hemant this forum is not appropriate for this question. However you have to analyze the system by meetings with stock broker at stock Exchange or to the client for which you are designing the system. Ask your superior to arrange meeting with client and then ask question to him so that you can made database design for them.

Database Design/Application architecture question

I'm working on a Java web app that includes creating a database from scratch. The UI needs to model a mostly static set of choices that led to other choices that lead to other choices..... I'm trying to figure out how to model this in a table or set of tables and how to design the UI and servlet interaction. Here's an example, in Petstore lingo:
Do you need a dog house?
For a small dog?
Red?
Blue?
How many?
For a big dog?
Brown?
Yellow?
How many?
Side windows?
Do you need a bird cage?
How many water dispensers?
For big bird?
This sort of multiple dependent options seems hard to model in a database. I'm trying to do this at the database level so that I can have a dynamic front end, in which I get the collection of options and then use JSTL to populate the UI with the chocies for whatever level or step I'm at. Any suggestions? I haven't had to solve a design problem precisely like this where some choices may have dependent choices, but others do not, and some have dependent choices which have very specific dependent choices that have very specific dependent choices. Thanks.

I'm working on a Java web app that includes creating
a database from scratch. You mean the UI drives creating the database?
Why?
That is often driven by developer rather than business requirements and is often a bad idea. It is often done solely so the developer doesn't have to type as much. And not typing very much is solved by code generation while using meta data solutions for it is usually a bad maintainance idea.
But if you need to then you create meta data.
Table TheValues
- Field: Value Id.
- Field: Value Name
- Field: Value Value
Table: Collection
- Field: Collection Id
- Field: Collection Name
Table: Link table
- Field: Collection Id
- Field: Id type
- Field: Id (Collection or Value)
Display values can be kept in another table or used directly.
Notice that a collection can contain another connection.
You can combine the first two tables as well.

Database Design for Multiple function site

Hi
I am working on one project which involve multiple function
site, such as
Company Product Catelog, Customer Support Forum, Document
Exchange Engine and
etc...
Normally we will combine ALL TABLEs into one DATABASE.
My question are:
1) Is my break them to individual DATABASE, will it perform
better?
Means Product Catelog and Forum will have different
DATABASE, but they
will using the same DOMAIN NAME.
2) I am worried about the break down and corruption of
DATABASE, so I have the
idea to separate them out. Are my idea correct or wrong?
3) I am seeking for better DATABASE DESIGN, because I know
the database will
become huge in future. I request for your idea and opinion.
Thank you very much.

Creating views: not an option I think. It would involve a lot of programming with 'instead of' triggers etc.
Seperate databases: a good way if the locations are completely independant and do not share information. This involves more DBA work.
Separate schema's in one database: this would make public synonyms impossible, and is probably not a good option.
Adding a location id to tables: the best way I think, and flexible. You can easily add another location, and locations can easily share information.

Database Designer App

Hi,
I need to make a database designer type application.
Where there are floating list boxes that can be moved around. Each of the list boxes will represent a tables and you can drag relationships between the list boxes which will create a line mapping the rows of the list boxes.
kinda like sql server or any type of RDB mapping tool.
Not really sure even how to start with the movable list boxes. Any suggestions?
Thanks,
-J

Nevermind, i found flexMDI which seems to work.
But not sure how to draw the lines and also be able to select the lines between the windows.

Suggestion: Create a Database Design Forum
