I've been hired to assist write a credit card applicatoin that handles certain information for that consumer. It is supposed to run a couple of mb of knowledge, but additionally manage scanned images entirely resolution. If this should project make use of a database, and why or why don't you?

Any question "Must I make use of a certain tool?" comes lower to asking precisely what for you to do. You need to request yourself - "Do I wish to write my very own storage with this data?"

Most internet based programs are written against a database since most databases support many "free" features - you could have multiple webservers. You should use standard tools to edit, verify and backup your computer data. You'll have a robust storage solution with transactions.

The database will not assist you to much in working with the look data itself, but something that handles a lot of images will have meta-data concerning the images that you will be coping with. With respect to the meta-data and what you would like related to it, a database can be very useful indeed with this.

And merely since the database does not assist you to much using the image data, that does not mean you cannot keep images within the database. You'd store these questions BLOB column of the SQL database.

If the quantity of information is small, or placed on many client machines, you will possibly not want the overhead of the database.

Could it be supposed to have been placed on many customers machines? Adding the overhead of making certain you are able to run whatever database engine you select on the client installed application isn't optimal. Since the quantity of information is small, I believe XML could be sufficient here. You can Base64 scribe the pictures and store them as CDATA.

Will the applying be operate on a server? For those who have concurrent customers, then databases have concepts to handle these situations (transactions), which could be useful. And also the scanned image data could be right for a BLOB.

You should not store images within the database, out of the box the overall consensus here.

The file product is just far better at storing images than your database is.

You need to use a database to keep meta details about individuals images, like a title, description, etc, and merely store a URL or road to the pictures.

If this involves storing images inside a database I avoid it. Inside your situation from things i can gather of the question there's a possibilty for any subsantial quantity of fairly large images, and so i would most likely strong oppose it.

If this sounds like an internet application I'd make use of a database for convenient searching and indexing of images using key phrases along with other parameters. Then possess a column pointing to the position of the image inside a filesystem if at all possible with a few type of folder structure to assist further reduce the image load time.

If you want greater security because of your directory being offered (network share) and also the application is local then you definitely should most likely bite the bullet and keep images within the database.

My stomach reaction is "why don't you?Inch A database will give a framework for storing information, with all the input/output/optimisation functions provided inside a recorded format. You are able to opt for a server-side solution, or perhaps a local database for example SQLite or even the local version of SQL Server. In either case you've got a robust, recorded data management framework.

This post should provide you with the majority of the opinions you'll need about storing images within the database. Would you also mean 'should I personally use a database for that additional information?A or are you currently just asking concerning the images?

Our Content management systems stores all the check images we process. It utilizes a database for metadata and allows the file system handle the scanned images.

An easy database like SQLite sounds appropriate - it enables you to store file metadata inside a consistent, transactional way. Then store the road to each image within the database and allow the file system do what it really does best - manage files.

SQL Server 2008 includes a new data type designed for in-database files, before that BLOB was the best way to store files within the database. On the small-scale that will work too.
