Not sure if you can do this easily on SQLite (with MySQL and PostgreSQL I have to create a new database connection. To jump from a particular client database to a shared common database I just say “USE DATABASE EmailSettings” and I’m there on the same connection. SQLite can’t do this.ĬubeSQL can hold an unlimited number of databases, each as a separate file. SQLite can’t do this.ĬubeSQL can communicate with the database over encrypted AES256 connections (without pesky certificates), so no one can sniff the network traffic to see what I’m sending. My desktop and web apps that access CubeSQL can be on entirely different servers essential to balance the load. If someone finds out my client password, they can read most tables, but not destroy anything. The client account cannot DROP or DELETE from most tables, even if you try. With SQLite I tend to open it when I open the app and leave it open for the duration of the app, so I’m not sure how this affects performance.ĬubeSQL gives me privileges, so I have two users defined: an admin and a client account. Unlike others, I use a different and new CubeSQL database connection every time I need one in a method, so when I need the server I really tax it, but when I’m not accessing the server, there are zero connections. Any large reads (pictures) I cache locally to a local SQLite file for faster access (wiping it on startup and shutdown) to speed up the server.
My database usage is 95% reads, which CubeSQL can do in parallel and supports multiple CPUs (which Xojo cannot) and lots of RAM. Yes, if your database needs are predominantly writes, then cubeSQL might not be for you as the writes are journaled one at a time.
I don’t see how potential corruption can be an issue that cubeSQLServer solves here, as SQLite itself won’t allow more than one writer at any moment in time. Is this just a performance issue that cubeSQLServer solves, in a high concurrency rate situation? That’s all that seems to be at issue here. I just don’t see why SQLite in WAL Mode couldn’t do this itself. So this would be a multiuser environment now, that supposedly cubeSQLServer makes okay. But I’m now considering having a particular SQLite file (hosted by cubeSQLServer) being written to by two different CGI apps. Until now, each SQLite file of mine has been accessed by a single CGI app, so I guess that really hasn’t been a multiuser environment.

Because this operation can insert or update an entity, it is also known as an upsert operation. The Insert Or Replace Entity operation replaces an existing entity or inserts a new entity if it does not exist in the table. So what does cubeSQLServer bring to the multiuser environment here that SQLite running in WAL Mode does not do alone? Insert Or Replace Entity (REST API) - Azure Storage. When a SQLite file is hosted by cubeSQLServer, that file is still only going to allow one writer at any moment in time.

So when working with your projects in the future, please do remember to index the fields that will be used for searching.I’ve been using cubeSQLServer now for a few years with Xojo Web apps, mainly because its Admin console is a very convenient manager of backup schedules of my various Xojo Web apps’ SQLite files, and it comes free with unlimited connections with ServerWarp. While it does take up more hard disk space, but it will also speed up the searches. It is the same here with the database, and indexing is creating a “catalog” for that selected field. But just imagine that the library is just a big random mess of books… You will literally have to look through each and every book to find what you want. Now, it will be easy to find if the library keeps a good catalog of the books they have. To explain that, I will give an analogy of someone searching for a book in a library. Some of you beginners will be wondering about what this does. Take note that both the name and email fields in the above examples are indexed – ADD UNIQUE KEY `email` (`email`) and ADD KEY `name` (`name`). The modeler uses IBM Cognos Cube Designer to create a basic dynamic cube. Also on the list, good to read up on CSRF and SQL injection. The Administration Console is used to deploy and manage the cube data. For example, check if an administrator is signed in before processing a search for sensitive data. A good system should have more security checks and stuff. That’s all for the search example, and here are a few extra bits that may be useful to you.Ī gentle reminder – This guide has only walked through the basics of a search system.
