This article will explain in detail how to conduct a comparative analysis of Access and SQLite. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

SQLite and Access, both of which are commonly used lightweight relational database systems. In the database ranking of DB-Engines, both of them are relatively high, and the ranking is also very close, indicating that there are still many people using the two databases, and it is difficult for many friends to choose between the two.

SQLite: I am small but sharp and tenacious!

SQLite, a lightweight, ACID-compliant relational database management system, is included in a relatively small C library. Mainly designed for embedded applications, widely used in many embedded products, she occupies very low resources, only a few hundred kilograms of memory is enough.

The author used Access for many years in his early years, mainly for local data storage, and understood the character and disadvantages of Access. Later, it was resolutely replaced with SQLite and has been used ever since. As a lightweight database, SQLite is as light as a feather but sharp and tenacious.

The SQLite database is a file. Because SQLite itself is written in C, and it is very small and efficient, it is often integrated into a variety of applications. At present, both Android and iOS use SQLite as a built-in database.

SQLite supports a variety of 32-bit and 64-bit hardware platforms, and can also run in Windows, Linux, BSD, Android and other software platforms. At the same time, SQLite supports most of the standards in ANSI SQL92, and provides support for subquery, view, trigger and other mechanisms.

The following figure shows the performance test comparison between SQLite and SQL Server and Acess:

As can be seen from the above table, it is easy for SQLite to crush Access.

Access: with Microsoft's blessing, even if the chicken ribs are gathered!

Access is a lightweight relational database management system released by Microsoft. It combines the characteristics of MicrosoftJet Database Engine and graphical user interface and is one of the optional suites of Microsoft Office office system.

Access is an Office suite and integrates well with Excel and Word. At the same time, Access supports Visual Basic macro language, and you can even develop simple systems directly in Access, which is a big advantage of Access over SQLite.

Of course, since Access is an Office suite, you need to pay for it if you want to use the Access environment to manage and maintain Access. However, if you call the Access database in the system you are developing, you can configure the calling environment, and you do not necessarily need to purchase Office.

Comprehensive comparison of advantages and disadvantages of SQLite and Access

The following inventory of the advantages and disadvantages of the two, you will suddenly be enlightened!

Advantages and disadvantages of SQLite:

Advantages:

1. Support Limit statements and automatic paging of data

2. Support Insert to return the ID that automatically increments the primary key

3. High query performance and efficiency

4. Support compression commands

5. Open source code, which can be embedded in dll for easy release.

6. Cross-platform, database has strong compatibility

7. Support the function of establishing database dynamically

8. Transaction processing

Disadvantages:

1. Lack of strong free query analyzer GUI. Charge has used SQLiteStudio, not bad!

Advantages and disadvantages of Access

Advantages:

1. Intuitive query analyzer GUI, which is easy to maintain.

2. The performance is average, but more mature and stable.

Disadvantages:

1. Limit command is not supported, so paging is difficult to do.

2. Insert is not supported to return incremental ID.

3. The concurrency performance is poor. The maximum number of concurrency is 50. Only one connection can modify the data.

4. Compression database command is not supported

5. Dynamic establishment of database is not supported

6. Cross-platform is not supported, which is a hard wound.

By comparison, we can draw the following conclusion:

SQLite performance crushes Access, but Access has Microsoft's blessing, although it is a chicken rib, it seems how important the support of the giant is!

This is the end of the comparative analysis of Access and SQLite. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
