About split databases
All Access database objects can either appear in one database file, or they can be retained in two database files (comprising a front-end database and a back-end database). This is known as splitting the database and its purpose is to simplify sharing in a network environment. The back-end database file must only include tables and relationships. The front-end file must only consist of all remaining objects, such as forms, reports, queries, macros, VBA modules, and related tables to the back-end database.
The process of migrating to an Access database is comparable to a split database by which that SQL Server is substituting as an emerged back-end for the data that is now based on a server.
Subsequently, you can still keep the front-end Access database with associated tables to the SQL Server tables. Consequently, you can earn the advantages of swift application development offered by an Access database, as well as the volume of SQL Server.
SQL Server Advantages
|More concurrent users||SQL Server can cope with substantially more concurrent users than Access. It also minimises memory requirements when additional users are added.|
|Increased availability||Using SQL Server allows you greater flexibility with backing up the database, either partial or complete. This has the benefit of not dictating users to leave the database for backing up data.|
|High performance and scalability||The SQL Server database typically has stronger operating capabilities than an Access database. This is particularly the case with a huge, terabyte-sized database. |
Additionally, SQL Server administers queries at a quicker and proficient rate by processing queries together. This is done by applying numerous native threads within one process to manage user requests.
|Improved security||With a reliable connection, SQL Server combines with Windows system security to supply an-all access route to both the network and database, utilising the superior aspects of both security systems. This minimises the difficulty of delivering complex security schemes. |
SQL Server is the convenient storage for sensitive details like Social Security numbers, credit card data, and confidential addresses.
|Immediate recoverability||If the operating system crashes or the power goes out, SQL Server can automatically recover the database to a consistent state in a matter of minutes and with no database administrator intervention.|
|Usage of VPN||Access and Virtual Private Networks (VPN) are usually mismatched. However, SQL Server enables remote users to still interact with the desktop-based Access front-end and the SQL Server back-end found before the VPN firewall.|
|Azure SQL Server||Further to SQL Server’s benefits, Azure provides adaptable volume with no lagging, intelligent optimisation, global expansion and accessibility, removal of hardware costs, and lesser administration.|
Choose the best Azure SQL Server option
Before migrating to Azure SQL Server, it is important that you consider three different options, each with their own unique benefits:
|Single database/elastic pools||This selection has its independent range of resources handled through a SQL Database Server. A single database is similar to a contained database in SQL Server. An elastic pool can also be inserted, which refers to a collection of databases with a shared selection of resources stored via the SQL Database Server. |
The high-demand SQL Server features are pre-populated with default backups, patching, and recovery. It is worth noting that there is no definitive maintenance timescale and migration from SQL Server might be challenging.
|Managed instance||This choice is a group of system and user databases with a shared collection of resources. A managed instance is comparable to the SQL Server Database which is operationally suitable with SQL Server. |
Unlike a single database and elastic pools, a managed instance is simple to migrate from SQL Server, although there are a few SQL Server functions that are absent and no confirmed maintenance duration.
|Azure Virtual Machine||This option facilitates running SQL Server inside a virtual machine in the Azure cloud. This gives you complete control over the SQL Server engine and a basic migration path. However, you must handle your backups, patches, and recovery.|
