I'm working on this project that requires my team and I to do a state of the art of existing Bluetooth modules and their characteristics. I thought it would be easier for us if we could just find a way to store everything we'll find in a programming interface, that is, we would just have to input the new data to a form and it would automatically update the underlying storage structure.
We need to be able to easily extract the created content and export it to .txt or .tex. The method used need to be easy to use, this is only a small part of the project and we don't have time to learn complex tools.
I know Javascript and a bit of C++. At first, I thought of creating an HTML form and use Js to take the input and add it to a JSON file that would then be transformed into an HTML table. This approach seems broken to me though, we wouldn't be able filter anything without writing lines of code and getting data from an HTML file with C++ must be a pain in the a**. Also, the JSON data would be in the browser local storage which is really not a good idea.
I also used SQLite a bit some years ago, and I remember that it is easy to filter the data. Does it sound like a good option to you ? Is it easy to add/retrieve data into/from an SQLite database ?
Thanks for the help !

I have this web application that gets and displays data from SAP, but i need a way (maybe a JSON file?) to share some data between different users, with the possibility to modify these same data for each user (even at the same time), without a database. There will be really small data and few users, and what i would write is simple data that tells me who is online in that moment. How can i do? I'd like to know if exist an easy solution to share these really small and simple data. I'm using React with no back, because i'm taking all the data i need from SAP. Clearly, i'm a beginner. All advice is welcome.
If you talking about some prototype like MVPs, I think JSON files would be best.
However, consider to work also that you can work with Local Storage.
You could use LocalStorage, SessionStorage or IndexedDB, but the last option is an in-browser database. Maybe LocalStorage is your solution.
I’m webGL engine developer (ThreeJS) in small company. We have some events in few weeks and my boss just told me that i have to make registration form as soon as possible, also one page should show names, lastnames and company of all registered members. Problem is that i’m very bad in databases and i have really small amount of time to re-learn it. How can i store registration data on Server without Database? I looked up on web and most instructions are unclear(because i’ve not worked on database before) and others are using localstorage (as far as i know its used for cacheing data)
What you're looking for is a flat file database system, try taffyDB it basically use Json to store its data or Papa parse that uses CSV files, you can easily edit with excel for example.
If you're really good with javascript you can consider using a real database after all,mongodb is a bit advance but still not as complicated as mysql or even sqlite.
I have an iOS app in which I use parse.com as backend service. Now, I hired someone to do a website interface using HTML and CSS. I want to share the same data between iOS app and website, I know parse.com offers me a few ways to do this, including creating a javaScriptapplication. The problem is, my programmer doesn't have any experience in JavaScript, nor do I.
My question is: Is it possible to use what I have (objective-c, xcode) as far as retrieving data from parse.com and showing on website? Even if I need to code something new, is it possible to use objective-c together with HTML and CSS?
Thanks.
Parse has several APIs, one of which is REST. Your web developer should use the REST API to get data from Parse

If there is will there is way, but you'll be making something really specific to your use and will be non standard and will be immediately hard to maintain, I recommend that you hire another developer and do things properly using the technologies given to you by parse !. if the cost will be high now I can promise you it'll be much higher if you went the path you're going to now.
So my answer is:
Yes, everything is possible and no, don't do it ! :)
Edit: Added an example to a possible way to do it to actually answer OP's question.
Example case:
1-Create a simple Mac Application in Xcode that fetches data exactly like you do it on iOS, and store the needed data into a database of your choice on your server
2-You now have access to the data you needed from parse, but on a local mirror. you will need some tool to fetch that data though, I recommend a simple PHP script.
Note that this will require an OSX server to always be running to fetch that data, you'll also need of find a way to fetch data on demand when a user needs it Vs. polling at specified intervals, this will hardly scale and will be costly as I said.
I'm planning to write a web app using either Backbone or Angular. We want to push "widgets" from the server to the client (i.e. semi-complicated, dynamic but largely autonomous UI elements... something maybe like the popular TodoMVC app). So we'll need to send over a template, some javascript (controllers etc.), probably CSS, and JSON data (models).
We're debating how to send over all the information. How much can be, and what should be encapsulated in the JSON?
Is it possible to create files out of data passed over? i.e. could we pull out CSS and apply the rules to our document? I believe it would be easier to run javascript passed over this way.
I'm under the impression that being able to cache the template is important... does that require loading it as a (separate) resource rather than as part of some huge JSON object?
As for CSS, it needs to be loaded before inserting into the DOM (so we don't want just a promise). Would it make sense - or even be possible - to pass our CSS rules in the JSON and extract them somehow?
EDIT: to more fully describe what I'm working with, I'm focusing only on the front-end. The back-end can be customized to send over resources however we want - they'll optimize that depending on what the front-end needs. Our backend stack includes MongoDB, Tapestry, ActiveMQ.
The payload that needs to get sent over will be all the resources necessary to push something like a Mac Dashboard Widget or Windows Gadget into the browser. So HTML, CSS, Javascript, data will all get sent over. We want things to be snappy and minimize server requests as much as possible, as some of these payloads may get to be somewhat large.
Your questions are rather vague and the answers can change by coding on a different build platform. Your chosen application design can also impact the best practices to follow for implementing X type of application to X device(s). There's more than one way to skin a cat ya know.
What information are you sending over? Is it a lot of raw data arrays? Is it more document based where XML could be more beneficial? You'll need to work with your DBA if the data is stored in a repository and you'll be querying it. Will you need to write code to format your data or will the DBMS output it in the format you need?
What do you mean the CSS needs to be loaded before being inserted? Everything loads in the order you specify so making sure your CSS loads at the proper time shouldn't be an issue. If you're using ASP.NET, you can also use a SSM (style-sheet manager) to serve your CSS and only load whats required. SSM's are great if you have a lot of style-sheets to serve.
A lot of the questions you asked will be answered as you get further into the design phase. In order to get some solid answers and not just speculation on what is the best method, you will need to publish a lot more details than this. Any answers at this point shouldn't carry much weight in your decisions. They certainly wouldn't mine.
I've created a list using XML and have embedded an XSL stylesheet in it. Now I want to know, because this is a list of movies that constantly grows, is there a way to create a form that will add child and grandchild nodes to the list.
I'm thinking there might be some javascript involved, but I have no idea what I'm doing when it comes to scripting.
If the intension is to write new entries into this xml file you need to look at some form of serverside scripting. Javascript can not write to files.
PHP is probably the easiest to understand, start by buying a book that explains the basics with a few examples, it's not that hard to grasp, and a form and a simple function for writing to files shouldn't take you to long to figure out.
If you have no interest in that sort of thing, hire someone to do the job for you, it will probably only take a few hours for someone who knows what they are doing to get a complete system up and running for you, and unless you really would like to learn a serverside language that is probably the best option.
If you really want to do it all on the client side, you can try HTML5 client-side storage. This means the data will be persistent only for the user that enters the data (and only for the browser used to enter it, and only on the computer that was used).
If you want the movies to be accessible to multiple people, or from multiple computers, you need to use server-side storage.
FYI, HTML5 storage is not yet very well standardized across browsers.
