If there are no used or less used indexes, it is better to drop those indexes in order to retain the disk space. Therefore, you need to manage indexes optimally. However, indexes will consume disk space. Indexes are implemented to improve the database performance of queries. Similarly, you should not use Unicode data types such as nvarchar, nchar unnecessary. For example, if you can use tinyint instead of int, you will be saving 3 bytes per row. You need to choose data types very carefully so that you can limit disk usage. Therefore, in the Express databases, you need to focus on design as well as for the archiving process of data. When data is in another database, the restoring process is much complex. However, in the SQL Server Express edition, it is essential to archive the data into a different database. In the standard or enterprise edition, you can simply archive the data into the same database. Whatever the option that you follow, it must be taken at an earlier stage of the system design in order to design and develop the relevant application.Īpart from the design strategies, you need to look at the data archiving strategies. Similarly, you can design your database so that data is kept for only a specific time period preferably for a year. Since the upper limit for the number of databases in a SQL Server Express edition is more than 32,000, you can create multiple databases in an express instance. For example, if you are running an Accounting system, you can create different databases for Accounts Payable, Accounts Receivable, Inventory and General Ledger domains, etc. You can distribute your data from a functional perspective. You need to look at database distribution strategies to maintain the 10 GB limit. Since you have a limitation of 10 GB for data, at the design stage itself, you need to look at what type of data that you are storing in your database. Since log file size will not count towards the database size, you can leave the database recovery model as Full orīulk-logged without impacting important recovery features as shown in the below figure. These configurations leave databases in a risk state. With this configuration, you are dropping the options of transactional log backup and importantly you will not have the option of point in time recovery. Most of the users configure the recovery model of the database in Express edition as Simple to reduce the transaction log file size. Since there is no limitation for the Express database transaction log file, you can leave the express database recovery model in either full or bulk logged. You will see that database is 24 GB which is clearly over the 10 GB limitation. This means log files can be in any size.įollowing is the Disk Usage report of the Express database which describes the limitations on the data and log files. However, it is important to note that this limitation is on the data file and the log file is excluded from this limitation. The major limitation in the SQL Express database is that the storage limit which is 10 GB. This edition will provide you with a basic storage option and this article is to examine what maintenance tasks you need to perform to manage SQL Express effectively. If you are not able to spend money on your small databases, SQL Server Express edition is the solution for you.
