The databases are uploaded from Workbench to Azure quickly, without asking to what tier you want to put them. The first punch in the eye is the price: $ 49.60 for a MySQL Server (against the $0 for SQL Server.) change the Pricing tier and scale up or down CPU, RAM and throughputĪ server contain databases… all good here… Let’s try to do the same with….see fancy metrics about DTU consumption.In this example I have created a server called jeejamigrationtest to which I have migrated 3 databases:Īnd this is what I have on Azure after migration, a server that contains 3 databases. Creating a SQL Server in Azure id free and or each database I’m paying $7.50 per month, the lower price. You still have to create a SQL Server and that server contains the databases. Well, if you are migrating SQL Server databases to Azure there is no problem. zip and extract the content you will see how each table is represented as a folder in which you can see the raw data. bacpac and then you rename the extension. (But I hope you have uninstalled Microsoft Access from your computer ages ago…). Is not different to what you see in Excel or in Access. Database tables consist of rows and columns. Table: In relational database terms, a table is responsible for storing data in the database.In DBMS you cannot relate data from different branches of your tree In RDBMS you have high freedom of relationship In the other hand in RDBMS there is no Hierarchy and you can create much complex relation between objects. That is the reason why in Hierarchical database the schema has a tree model: that’s because there is a Hierarchy. Schema: The schema of a database is a virtual representation of the relationship between the data within a database.The Oracle Office has a design that recalls the cylinder database shape SSMS is asking you to attach a device… c’mon chunk it in! In the middle of the ’90, when the OS didn’t needed a dedicated file system any more “C:\” was the next letter available and they used that to keep backward compatibility for A and B. Today a backup is a simple file on a file system but before you physically had to connect the hardware database.įun fact: do you know why in Windows the hard drive is called “C:\” ?īecause “A:\” was the slot you used for the OS (yes, you had to insert the OS every time) “B:\” was the slot you used to copy file in case you had to copy or extract files from the “A:\” drive. That’s why, still today, when you want to restore a backup in SSMS the GUI will prompt you with the “Device”. And they were the very first hard drives too. Database: The cylinder shaped icon comes from the fact that they were magnetic disc storage one upon each other.The first WWW server located at CERN with its original sticker that says: “This machine is a server. The first iteration of Google production servers was built with inexpensive hardware and was designed to be very fault-tolerant. We will eventually dedicate a room to them later on… and because the carpet is full of dust let’s squeeze them all into a closet. Also because probably someone was visiting the website from another time zone. And people wanted to read their mails at night and visualize websites at any time. At the very beginning they were mere computer towers, positioned below a desk, warming the developer’s feet with their fan during working hours.īut then internet came along bringing Mail servers and Web servers.
