Best Practice for storing PDF docs

My client has a number of PDF documents for handouts that go
with his consulting business. He wants logged in users to be able
to download the PDF docs for handouts at training. The question is,
what is the 'Best Practice' for storing/accessing these PDF files?
I'm using CF/MySQL to put everything else together and my
thought was to store the PDF files in the db. Except! there seems
to be a great deal of talk about BLOBs and storing files this way
being inefficient.
How do I make it so my client can use the admin tool to
upload the information about the files and the files themselves,
not store them in the db but still be able to find them when the
user want's to download them?

Storing documents outside the web root and using
<cfcontent> to push their contents to the users is the most
secure method.
Putting the documents in a subdirectory of the web root and
securing that directory with an Application.cfm will only protect
.cfm and .cfc files (as that's the only time that CF is involved in
the request). That is, unless you configure CF to handle every
request.
The virtual directory is no safer than putting the documents
in a subdirectory. The links to your documents are still going to
look like:
http://www.mysite.com/virtualdirectory/myfile.pdf
Users won't need to log in to access these documents.
<cfcontent> or configuring CF to handle every request
is the only way to ensure users have to log in before accessing
non-CF files. Unless you want to use web-server
authentication.

Best Practice for storing a logon to website in a desktop java app

Hoping someone well versed in java related security best practices can point me in the right direction.
I have a small java PC application that uses the Soap API to send various data to a 3rd party.
Currently I am storing the logon credentials for this 3rd party in a local database used by the application.
The username / password to connect to this database is encrypted and never accessed in clear text in the code.
(Although, since the application is stand alone, everything needed to decrypt the database credentials is packaged
with the application. It would not be easy to get the clear text credentials, but possible)
The caveat in my case is that the user of the application is not even aware (nor should be) that the application is interacting with
the 3rd party API at all. All the end user knows is that an entity (that they already have a relationship with) has asked them to
install this application in order to provide the entity with certain data from the user.
Is there a more secure way to do this will maintaining the requirement that the user not need know the logon credentials to the 3rd party?

Moderator advice: Don't double post the same question. I've removed the other thread you started in the Other Security APIs, Tools, and Issues forum.

Best practices for storing logon/password info

I'm curious what are the best practices and/or what other organizations are using to store the logon/password information that needs to be shared by several users. This could be, for example, RFC logon that is used in several interfaces; FTP logon, etc. Such information may need to be accessible to all the developers yet should be stored safely.
In my previous assignments this was usually managed by a Basis admin, but we don't have a designated admin here so it needs to be handled by developers. A suggestion has been made to store it in a Z table in SAP, but we're trying to explore other options.
Thank you.

The SecureStore is a protected area only accessible via the SAP kernel functions. It is SAP standard (used by transactions such as SM59, etc) and is accessed by the system at runtime.
But if you only want these connections to be temporarily available (so, without stored logon data) then there is a guru solution you might want to consider for those access in ABAP systems.
For general password management of generic users or large numbers of them you can alternately also consider a [password-vault|http://www.google.com/#hl=de&source=hp&biw=1276&bih=599&q=password+vault&rlz=1R2ADSA_deCH392&aq=f&aqi=g3&aql=&oq=&gs_rfai=&fp=ec103d87630c3cc0] . These can however typically not be accessed at runtime.
Shall I move this to the security forum, ABAP general, NW Admin or is someone still going to get themselves Guestified here?

Best practice for end user menu pages

Hi
here is my goal :
i want to add a link on the end user menu offering the user the ability to reset some LDAP fields (for example reset default values for mail settings after the user made a wrong customization).
I saw all links on the end user menu are pointing to jsp pages. must i do the same or can i achieve my goal with only workflows and forms in the BPE ?
is there somewhere a good example or a best practice desciption of such a customization ?
thanks a lot

thanks a lotDo you mean adding additional tabs to the accounts information (default being identity, assignments, security, and attributes). So, you want an additional tab such as 'LDAP attributes' after attributes, once you have assigned LDAP resournce to that user, right?

On best practices for minimizing user impact for db/dw migrations

Hi Everybody!
Our department will be undertaking the migration of our ODS and Datawarehouse to Oracle 10g in the coming months and I wanted to query this group in anticipation for any good tips, DOs and DON'Ts and best practices that you might want to share with the group on how to minimize user impact, especially when some of the queries that different departments use have no known author and would need to be migrated to a different database dialect. Our organization is a large one and therefore efficacy in communicating the benefits of our project and handling a large number of user questions will be key items in our conversion plan.
Thanks a lot to all those who can contribute to this thread, hopefully it will become a good way to record the expertise of this group's members on this very specific project category.
-Ignacio

BTW it is not clear from WHAT you want to migrate? Other DB or simply other Oracle version?
OK anyway speaking about Data migration strategy there is at least one valueable article
http://www.dulcian.com/papers/The%20Complete%20Data%20Migration%20Methodology.html
Speking about technical execution you can look at my article Data migration from old to new application: an experience at http://www.gplivna.eu/papers/legacy_app_migration.htm
None of them focuse on datawarehouse though.

Best practice for storing/loading medium to large amounts of data

I just have a quick question regarding the best medium to store a certain amount of data. Currently in my application I have a Dictionary<char,int> that I've created, that I subsequently populate with hard-coded static values.
There are about 30 items in this Dictionary, so this isn't presented as much of a problem, even though it does make the code slightly more difficult to read, although I will be adding more data structures in the future with a similar number of items.
I'm not sure whether it's best practice to hard-code these values in, so my question is, is there a better way to store this information, retrieve and load it at run-time?

You could use one of the following methods:
Use the application.config file. Upside is that it is easy to maintain. Downside is a user could edit it manually as its just an xml file.
You could use a settings file. You can specify where the setting file is persisted including under the user's profile or the application. You could serialize/deserialize your settings to a section in the settings. See
this MSDN help section
on details abut the settings.
Create a .txt, .json, or .xml file (depending on the format you will be deserializing your data) in your project and have it be copied to the output path with each build. The upside is that you could push out new versions in the future of the file without
having to re-compile your application. Downside is that it could be altered if the user has O/S permissions to that directory.
If you really do not want anyone to access it and are thinking of pushing out a new application version every time something changes you could create a .txt, .json, .xml file (depending on the format you will be deserializing your data) just like the previous
step but this time mark it as an embedded resource in your project (you can do this in the properties of the file in visual studio). It will essentially get compiled in your application. Content retrieval is outlined in
this how to from Microsoft and then you just deserialize the retrieved content the same as the previous step.
As far as formats of your data. I recommend you use either XML or JSON or a text file if its just a flat list of items (ie. list of strings). Personally I find JSON much easier to read compared to XML and change and there are plenty of supported serializers
out there. XML is great too if you need to be strict as to what the schema is.

Best Practice for Storing Sharepoint Documents

Hi,
Is there a best practice where to store the documents of a Sharepoint? I heard some people say it is best to store sharepoint documents directly into file system. Ohters said that it is better to store sharepoint documents into a SQL Server.

What you are referring to is the difference between SharePoint's native storage of documents in SQL, and the option/ability to use SQL's filestream functionality for Remote BLOB Storage (also known as RBS). Typically you are much better off sticking with
SQL storage for BLOBs, except in a very few scenarios.
This page will help you decide if RBS is right for your scenario:

Best practices for multiple users on a network?

We have a centralized server storing all of our media, and a Final Share system allowing about 10 clients to connect. The details of the system aren't important, it mounts just like a local drive on each client and bandwidth is higher than FW800.
My question is what is the best way to handle cache files, sidecar files, autosave, etc. when passing edits between editors? What should be stored locally, what can be placed on the server? Of course all media has to be placed on the server, but can everything else sit alongside the footage?
The reason I ask is we started by pointing everything at the server, but now are having the good old Serious Error whenever two editors (in different project files) are referencing the same media. We'd love to resolve this... assistant editors can't log footage if doing so causes the editor's project file to lock up.
Thanks!
P.S. first tried called adobe phone support about this... not making that mistake again. The most apathetic customer service rep I think I've ever spoken with told me they wouldn't provide support because our Serious Error was the result of network issues and not their fault. And then that we should be storing our media files locally. I didn't see it necessary to mention that local storage on 10 machines isn't that viable with almost 50TB of data.

Hi Klonaton.
Are you using two Premiere projects or one Prelude project (for logging) and one Premiere project (for editing) ? I'll have to check tomorrow to be absolutely sure but we do sometimes have simultaneous logging and editing with -respectively- Prelude and Premiere through our small network, with no issues.
Changes to metadata and comment markers created into Prelude instantly appears and update into Premiere. Subclip don't and have to be sent from Prelude to Premiere on the same computer (or the media has to be imported again inside Premiere). I think it's normal considering how subclips work a bit differently in Prelude and Premiere.
Every files are on a thunderbolt raid drive shared on the network through an iMac. The Media Cache and Media Cache DB are on the network shared drive too, and common to every users and computers.
Also I don't get if crashes happen when your two projects are running simultaneously or not (in the latter case, that's a huge problem).

Best Practice for Storing Program Config Data on Vista?

Hi Everyone,
I'm looking for recommendations as to where (and how) to best store program configuration data for a LV executable running under Vista. I need to store a number of things like window location, values of controls, etc. Under XP I just stored it right in the VIs own execution path. But under Vista, certain directories (such as C:\Program Files) are now restricted without administrator rights, so if my program is running from there, I dont think it'll be able to write its config file.
Also right now I'm just using the Write to Spreadsheet File block to store my variables. Does this sound alright or are these better suggestions?
Thanks!
Solved!

Application settings that need to be
changed at run time should be stored in one of the following
locations:
 CSIDL_APPDATA
 CSIDL_LOCAL_APPDATA
 CSIDL_COMMON_APPDATA
Documents saved by the user should be
stored in the CSIDL_MYDOCUMENTS folder.

Best practice for storing price of an item in database ?

In the UK we call sales tax, VAT, which is currently 17.5%
I store the ex-VAT price in the database
I store the current VAT rate for the UK as an application variable (VAT rate is set to change here in the UK in January)
Whenever the website display the price of an item (which includes VAT), it takes the ex-VAT price and adds the VAT dynamically.
I have a section in the website called 'Personal Shopper' which will happily search for goods in a fixed priced range eg. one link is under £20, another is £20-£50
This means my search query has to perform the VAT calculation for each item. Is this practice normal, or is it better to have a database column that stores the price including VAT ?

I'm also based in the UK, and this is what we do:
In our Products table, we store a Product Price excluding VAT and a VAT rate ID, which is joined off to a VAT Rates table. Therefore in order to calculate selling price yes, this is done at the SQL level when querying back data. To store the net, vat and gross amounts would be to effectively duplicate data, hence is evil. It also means that come January we only have to update that one row in one table, and the whole site is fixed.
However.
When someone places an order, we store the product id, net amount, vat code id, vat amount and vat percentage. That way there's never any issue with changing VAT codes in your VAT codes table, as that'll only affect live prices being shown on your website. For ever more whenever pulling back old order data you have the net amount, vat amount and vat percentage all hard-coded in your orders line to avoid any confusion.
I've even seen TAS Books get confused after a VAT change where in some places on an order it recalculates from live data and in others displays stored data, and there have been discrepancies.
I've seen many people have issues with tax changes before, and as database space is so cheap I'd always just store it against an order as a point-in-time snapshot.

PC Convert - Configuring Mail & Best Practices for Multiple Users

I finally came to the light side last night. I bought an iMac and now I'm trying to figure out how to best set it up for use by me and my wife. Our PC is set up with a single login account and I've created multiple Outlook (not Express) profiles, one for her and one for me.
Can I do the same thing on the iMac? Am I better off creating multiple login accounts and just keeping everything separate? Being new, I would rather set things up the right way the first time and not have to undo things due to my lack of experience with iMac.
Thanks!

Hello,
Welcome to the Discussions, and welcome to Macs!
If you each wish not to see the email messages of the other, then your only real choice is to set up separate User Accounts (what you are calling login accounts). Of course using a single User Account, you can set both email accounts up in Mail, and if you keep the Inbox and Sent mailboxes expanded to show the separate Inbox (and Sent) for each account, then that works pretty well. It will not distinguish New Mail without looking in the the Inbox -- the red dot in the Dock will not separate for whom new mail has arrived. But the Address Book will be the same and shared.
The advantage of multiple User Accounts is that the entire Dock can be customized for the applications each of you like to use, if they are different.
The disadvantage will be in not sharing will include not sharing the Address Book, music and photo libraries, etc.

Best Practice for Storing Spatial Data in Multiple Projections?

From what I've been able to determine MS SQL can't do reprojections is that correct? Assuming it is, the state of Washington requires that our GIS data be managed in Washington Stat Plane South
but for our web mapping sites need the data in Web Mercator. Is it OK then to have two geometry columns in a spatial enabled table, say a county table, one in WSPS and the other in WM?
I’m coming at this from a 30 year background in GIS using ESRI software.
Usually we would store the shape / geometry in one projection and project it to other on the fly when needed.
That way there is only one definitive source. I don’t see a way to do this in MS SQL.

Hi Scott.
Storing two columns of spatial data is fine in SQL Server. And you are correct that there is no built-in reprojection in SQL Server, most folks do that as part of data loading. There was talk of porting parts of ogr2ogr to SQLCLR, but I don't think anyone
did that.
Cheers, Bob

Best Practice for General User File Server HA/Failover

Hi All,
Looking for some general advice or documentation on recommend approaches to file storage. If you were in our position how would you approach adding more rubustness into our setup?
We currently run a single 2012 R2 VM with around 6TB of user files and data. We deduplicate the volume and use quota's.
We need a solution that provides better redundancy that a single VM. If that VM goes offline how do we maintain user access to the files.
We use DFS to publish file shares to users and machines.
Solutions I have researched with potential draw backs:
Create a guest VM cluster and use a Continuosly Available File Share (not SOFS)
- This would leave us without support for de-duplication. (we get around 50% savings atm and space is tight)
Create a second VM and add it as secondary DFS folder targets, configure replication between the two servers
- Is this the prefered enterprise approach to share avialability? How will hosting user shares (documents etc...) cope in a replication environment.
Note: we have run a physical clustered file server in the past with great results except for the ~5 mins downtime when failover occurs.
Any thoughts on where I should be focusing my efforts?
Thanks

If you care about performance and real failover transparency then guest VM cluster is a way to go (compared to DFS of course). I don't get your point about "no deduplication". You can still use dedupe inside your VM just will have sure you "shrink" the VHDX
from time to time to give away space to host file system. See:
