What is the best database alternative?

I am collecting data (alarm & counter) from several serial devices which have memory and RTC. Therefore I have to take into account that the collected data will not be chronological and I may need to sum newly collected data to existing records and then overwrite the record. It is possible to reach about 50,000 records/month. In addition, I need to add the data together and graph hourly, daily, weekly, monthly, etc. So read speed is very important for user interaction.
Can someone recommend the best file type or data management practice for this? I am using LV 8.5, so would like to use TDMS but cannot overwrite records in this version. Currently I've settled on MGI Read/Write Anything, but is this the best solution? I'd like to avoid DB Connectivity Toolkit and don't think I'd get any speed advantage anyway. I just need the best way to pull out an individual record, overwrite it, and scan quickly through the entire file.
Are there any other tools in later LV versions other than overwriting TDMS records?
Clint
Solved!
Go to Solution.

Consider SQLite, a very fast "database in a file". The LabVIEW wrapper I use is here; no DB Connectivity Toolkit needed. All the stuff you describe is easy in SQL. Write speed is greater than 100k timestamped readings per second, and read speed is higher. You'd need to upgrade your 8.5 LabVIEW, though.

What is the best iBook alternative

I was so looking forward to being able to read my books on my Mac but after experiencing the debacle that is the iBook app I've already moved my collection back to iTunes and deleted iBooks.
So my question is, what is the best alternative to iBooks? Assuming there is an alternative - I'm sure all the books I've purchased from the iBook Store are overflowing with DRM.
I'd prefer not to have multiple libraries - I like the way iTunes manages my collection. In a perfect world I'd like to be able to double click on a book in iTunes and have it simply open up on my Mac for reading, highlighting, notating, etc...(which is kind of how I expected the iBooks app to work)
Is there anything out there that comes close to that?
Cheers,
David

Here is how to delete iBooks and get book management functionality back to iTunes:
1. Open Activity Monitor and kill the bookstoreagent service.
2. Delete the file for that service:/System/Library/PrivateFrameworks/CommerceKit.framework/Versions/A/Resources/boo kstoreagent
3. Use AppCleaner to remove iBooks app completely.
4. Restart iTunes and Books menu will appear again there.
5. Copy our ebook files from our backup back to internal storage. This is mainly for ebook files that we didn’t purchase from iBookstore. Don’t worry about books that we purchased from iBookstore, we can re-download them again.
6. Delete the ebook files from~/Library/Containers/com.apple.BKAgentService/Data/Documents/iBooks/Books so iTunes library will detect them as missing. Right click for each book, choose “Get Info” and it will ask the location of the file. Point the location to the ebook file that we have restored. Yes it’s probably a long and tiring process especially if we have plenty of books.
7. An alternative way of step 6 is to delete all the books from iTunes library and re-import them from the files. All the metadata we created before should remain unchanged.
8. Re-download books that we purchased from iBookstore. Or alternatively if we have those books in our iPhone or iPad, we can just sync them with iTunes and choose to transfer those books.

What is the best limewire alternative for 10.4

What is the best alternative ti Limewire for Mac OS X 10.4.11.

None... Don't use it. Most that is available via Limewire is illegal, not to mention can open yourself up to hacked versions of software being sent your way. Get the genuine article from http://www.macupdate.com/ or C!Net's replacement for http://www.versiontracker.com/ Do not use MacKeeper either, as that is malware.

What is the best database freeware for Tiger?

Hello,
I try to learn to create database on my G4 running Tiger.
Anyone can tell me what is the best freeware to begin with?
Do I need to install a database server as well?
Thank you
Benny Lee

Got it.
So you can scratch AppleWorks and possibly LibreOffice off your list.
If you want to make a web form, then you will need to resort to your Dreamweaver connected to any database (again, you Mac OS X already has MySQL installed, it is jsut not turned on by default.
An important question is:
Where will you host this site?
If you are hosting it locally on your machine, you'll need to take into account the webserver (OS X uses Apache by default) and most certainly will need to deal with lousy upload network speeds, firewall, port forwarding on your router etc... I'd strongly recommend you install MAMP becuase it has some great maintenance and setup tools bundled in.
If you'd be publishing this form via some web hosting service (FatCow, GoDaddy, etc....) you'd need to make sure your service provides MySQL access on their servers and set it up.
If you really want to do this fast and already know some SQL basics and want to use rapid development tools, Oracle's ApEx is IMHO the easiest way to do that.
You can register for free @ apex.oracle.com and get 25MB of free space - all would be done via web browser, creating tables, queries, users, etc... Form would be created using their application builder tools. It would at least give you an idea what what it is capable of and if you'd like it, you could install Oracle 11g XE for free. It has a limit of using only 1 CPU, can have only 1 instance running and has a limit of some 11GB in size I think, but other than that, it is a mighty powerhouse which bundles database, webserver and front end website building tools all in one package, with no price tag.

What is the best Database Administrator Tool

In my one of my earlier organizations DB administration jobs were done with TOAD. In my next organization my Project manager told that TOAD is actually meant for developers. There the tool was DBArtisan. Now in my present company I would have to take the decision to purchase some DB Administration tool. What should I select ? Any of the two ? Or any third one ? If any suggestion comes it will be a great help for me.
I am using Oracle 8x,9x10g
and the OSs are Unix AIX, Windows etc

It really depends on what you mean by 'Administer the database', 'Database Administrator Tool' and so on. In other words, it depends on what you really want to accomplish.
Many people want a tool to put up pretty pictures and respond to mouse clicks to 'do things'. There are a fair number of tools that accomplish this very well.
TOAD was originally for developers (hence the name Tool for Oracle Application Developer), but it has expanded dramatically to include a number of DBA capabilities. Quest, BMC, Computer Associates and others have excellent tools that are heavily into the 'draw a picture and lead the budding DBA in complacency'.
Even Oracle Enterprise Manager is great from that perspective AND it's free!!! Well, except that you license and pay for the add-on packs that make it truly useful.
To paraphrase Nicolas - the best DBA tool is an intelligent DBA using SQLPlus. All other tools will lead down the path that the tool developer has decided to use. Which may be right for some of the time, but is rarely right all the time, and rarely completely right for the latest and greatest releases of Oracle.

What is the best iTunes alternative for a 4th Generation iPod Touch?

iTunes is the worst music application I have ever used and would love to be able to use a different application to sync music with. I have a really nice computer, but it is taking 10 times longer to sync music than Windows Media Player. I'm beginning to understand all the hate people have for Apple, besides how over-priced all their products are.

Found one.
Are you sure? That doesn't look (to me) as though it's suitable for managing an iPod.
I'm guessing, since you mention Windows Media Player, that you have been using it for a while and have just bought yourself an iPod. In that case, you simply need to get used to iTunes, in the same way as a car driver needs to get used to a new vehicle or a new employee has to get used to the demands of his or her new job.
I find iTunes much better for managing the device it has been designed to work with (Apple products) than anything that other MP3 players or Portable Media Players use. Often the software used to manage other MP3 players isn't specifially designed for the device at all and it can be like forcing a round object into a square hole.
Try understanding how you can get can get the best out of iTunes instead of trying to make it do what Windows Media Player does.

What is the best Mac alternative to Tag & Rename

Hi
On my PC I near-daily used a programme called Tag&Rename to manually manage my MP3s.
I found itunes never tagged correctly and often screwed them up with wrong imagery etc.
Details of Tag&R here: http://www.softpointer.com/tr.htm
Tag & Rename was ideal - I could change literally every tag in the MP3 - both singularly or as an album or compilation. It even allowed me to highlight a selection of MP3s and auto tag them according to Amazon - including adding file and folder images.
I've now replaced my PC with a Macbook Pro and sadly Tag&Rename is not available
Can someone advise me on the best alternative please - either as a software download or from the Mac App Store.
I'm happy to pay for it as I have a lot of MP3s and it something I used daily
Thanks in advance

Fatboyslick,
I have not found a program for the MAC as good as Tag&Rename. Music Tag Editor is as close as I can come to Tag&Rename. I have asked the developer of Tag&Rename if a MAC version would ever be possible for a MAC version and he indicated that he was currently working on one. I have no idea where he is at on the development.
The best thing about Tag&Rename was that I could tell it where to save the file by automatically telling it the drive\directory\artist name\album name\title.mp3
Music Tag Editor lets you rename the file and do a SaveAs but it is way to many steps and I have to change the directories for every artist. You can't create a driectory within the program....
So in short. There is nothing in the MAC world that is as good as Tag&Rename.

What's the best database app for the ipad2

looking for a database for my ipad2 - i want to put my books on it so i don't buy the same ones over and over again

Yes a simple spreadsheet will do the trick. If you want a more sophisticated database just for books then search in the app store for 'My Library' and 'iBookshelf'
I personally use 'Delicious Library' on my mac with a companion app on iphone that syncs with the mac app. No Ipad app is out yet for this.
If you want a general Database for various uses then Bento would be the way to go.

What is the best database management system for keynote slide library

I am trying to save slides from keynote so I can use them again in different presentations is there an easy to use database management system out there or a way to compare the ones that are available?

The simplect is to save individual Keynote files then use spolight to search for metadata placed in the file: Inspector > Document >Spotlight

What is the best methodology to handle database schema changes after an application has been deployed?

Hi,
VS2013, SQL Server 2012 Express LocalDB, EF 6.0, VB, desktop application with an end user database
What is a reliable method to follow when there is a schema change for an end user database used by a deployed application? In other words, each end user has their own private data, but the database needs to be expanded for additional features, etc.
I list here the steps it seems I must consider. If I've missed any, please also inform:
(1) From the first time the application is installed, it should have already moved all downloaded database files to a separate known location, most likely some sub-folder in <user>\App Data.
(2) When there's a schema change, the new database file(s) must also be moved into the location in item (1) above.
(3) The application must check to see if the new database file(s) have been loaded, and if not, transfer the data from the old database file(s) to the new database file(s).
(4) Then the application can operate using the new schema.
This may seem basic, but for those of us who haven't done it, it seems pretty complicated. Item (3) seems to be the operative issue for database schema changes. Existing user data needs to be preserved, but using the new schema. I'd like
to understand the various ways it can be done, if there are specific tools created to handle this process, and which method is considered best practice.
(1) Should we handle the transfer in a 'one-time use' application method, i.e. do it in application code.
(2) Should we handle the transfer using some type of 'one-time use' SQL query. If this is the best way, can you provide some guidance if there are different alternatives for how to perform this in SQL, and where to learn/see examples?
(3) Some other method?
Thanks.
Best Regards,
Alan

Hi Uri,
Thank you kindly for your response. Also thanks to Kalman Toth for showing the right forum for such questions.
To clarify the scenario, I did not mean to imply the end user 'owns' the schema. I was trying to communicate that in my scenario, an end user will have loaded their own private data into the database file originally delivered with the application.
If the schema needs to be updated for new application features, the end user's data will of course need to be preserved during the application upgrade if that upgrade includes a database schema change.
Although I listed step 3 as transferring the data, I should have made more clear I was trying to express my limited understanding of how this process "might work", since at the present time I am not an expert with this. I suspected my thinking
is limited and someone would correct me.
This is basically the reason for my post; I am hoping an expert can point me to what I need to learn about to handle database schema changes when application upgrades are deployed. For example, if an SQL script needs to be created and deployed
then I need to learn how to do that. What's the best practice, or most reliable/efficient way to make sure the end user's database is changed to the new schema after the upgraded application is deployed? Correct me if I'm wrong on this,
but updating the end user database will have to be handled totally within the deployment tool or the upgraded application when it first starts up.
If it makes a difference, I'll be deploying application upgrades initially using Click Once from Visual Studio, and eventually I may also use Windows Installer or Wix.
Again, thanks for your help.
Best Regards,
Alan

What is the best form to control a open of database?

Hi,
what is the best form to open a database?
I´m understood that Environment is unique for all aplication, and I think that it is good to put on Singleton Pattern, but I don´t know the best form to do it with the databases.
I think two forms, the first is create a singleton open database, with this form I don´t will close the database and all application will use it. So, the second form is open a data base at the moment that I will use it, for example, into a DAO when I will do inserts, deletes, etc, and at the final of the operation I close the database.
So, I don´t know what form is the best, and if those forms are corrects, if exist another form to do it I would like to know.

Hugo,
An application can choose to use one or more Environment and Database instances in a single process. In other words, it is the application's choice whether it wants to instantiate a single Environment or Database and share it among multiple threads, or whether it wants to instantiate multiple instances.
Choosing one pattern or another is a function of your application's design, and performance considerations. As you say, you could instantiate a single Database instance and pass it around, or you could open and close the Database every time you get a data record. A third choice is to open a Database instance per thread, and reuse that for the life of the application.
The second choice of opening and closing the Database per data record access is pretty heavyweight from a performance point of view. There is a fair bit of overhead to the initial open of a database, and to the final close. Follow-on opens are not as heavyweight, but do have some cost. For example:
// expensive
thread 1 calls Environment.openDatabase() or new EntityStore()
// less expensive, database is already open, thread 2 is really just getting a handle
// onto the database, but still more expensive than a read or write of a data record
thread 2 calls Environment.openDatabase() or new EntityStore()
The first choice of using a single Database instance in your process will perform much better. If your application has a high level of concurrency, there can be some contention on the Database instance, described in this FAQ - http://www.oracle.com/technology/products/berkeley-db/faq/je_faq.html#32 and you may prefer to try the third option of using a Database instance per thread.
Regards,
Linda

Hi Shane. Not much in the way of thoughts - - but fwiw:
How is the drive attached?
Can you open large files on the drive with other programs?
Are you running any drive compression or acceleration programs (some drives arrive with these installed)?
Can you reformat the drive and try again?
Hi Kirby,
I attached the UltraMax Plus with a USB cable. The UltraMax powers the cable so power is not an issue. I can open other files. Also, there is 500GB of files on the drive so I cannot re-format it. Although, I noted I could import the entire Aperture Library. However, I do not want to create a duplicate on my machine because that would be defeating the purpose of the external drive.

Database Log File becomes very big, What's the best practice to handle it?

The log of my production Database is getting very big, and the harddisk is almost full, I am pretty new to SAP, but familiar with SQL Server, if anybody can give me advice on what's the best practice to handle this issue.
Should I Shrink the Database?
I know increase hard disk is need for long term .
Thanks in advance.

Hi Finke,
Usually the log file fills up and grow huge, due to not having regular transaction log backups. If you database is in FULL recovery mode, every transaction is logged in Transaction file, and it gets cleared when you take a log backup. If it is a production system and if you don't have regular transaction log backups, the problem is just sitting there to explode, when you need a point in time restore. Please check you backup/restore strategy.
Follow these steps to get transactional file back in normal shape:
1.) Take a transactional backup.
2.) shrink log file. ( DBCC shrinkfile('logfilename',10240)
The above command will shrink the file to 10 GB.(recommended size for high transactional systems)

"NEVER SHRINK DATA FILES", shrink only log file
3.) Schedule log backups every 15 minutes.
Thanks
